  • License Plate Recognition Software (LPR) Is Often Confusing? These Practical Things Are Easy To Understand

    Hello everyone! In today's daily life, license plate recognition software, which is what we usually call LPR (Plate), occurs very frequently in parking lot management and traffic violation handling. Many friends have various confusions about what this thing is and how to choose. Today, I will talk to you about the practical and practical things about this LPR software, hoping to help those in need.

    Simply put, LPR software is a computer program that can automatically identify the license plate number by the vehicle picture taken through the camera, right? Its workflow is roughly divided into several steps: first, you have to use a camera to take a picture, and then process the captured pictures, such as adjusting the brightness of the picture and removing noise from the picture. After that, you can find the position of the license plate from the picture, then divide the characters on the license plate, and finally use a special recognition algorithm to turn the characters into text numbers… The whole process seems quite simple, but in fact the technology involved is quite complicated. Of course, if you have the need to purchase weak current intelligent products, you can provide global procurement services for weak current intelligent products!

    Next are several key modules to focus on when choosing LPR software. These modules will affect the best use of the software:

    1. Identification accuracy: This is definitely what everyone cares about the most, right? A good software can have an accuracy rate of more than 99% when the environment is good. Even if the light is not good and the license plate is a little blurred, it can still have about 95%. If the accuracy rate is too low, it will be too difficult to use.

    2. Processing speed: It is the time it takes for the software to take pictures to recognize the results. Generally speaking, it must be within 1 second. If the processing speed is slow, it will easily cause congestion when there are too many cars, which will be troublesome.

    3. Compatibility: The software must be compatible with most cameras and computer systems, otherwise it will be useless if you buy it and cannot install it or use it.

    4. Functional expansion: Can you add some functions according to your needs, such as counting daily traffic, binding vehicle entry and exit records, etc., software with good function expansion is more flexible to use.

    Here are some common questions to solve your doubts:

    Q: Do LPR software have any special requirements for cameras?

    Answer: Generally speaking, high-definition cameras are required, with pixels at least 720P or above, preferably 1080P. Moreover, the angle and height of the camera are also given due to the angle and height. Too much angle and inappropriate height may affect the recognition effect… So you have to choose the right one when buying a camera.

    Q: Can LPR software accurately identify it at night or rainy days?

    Answer: Good software will have functions such as infrared fill light and low light noise reduction, which can be recognized at night. However, if the rain is too heavy and the rain blocks the license plate, it will not work. However, the recognition rate of normal rainy weather can still be guaranteed to be above 90%.

    Another comparison is, what is the difference between some cheap LPR software and more expensive software? Cheap software may have low recognition accuracy, few functions, and after-sales service, and problems will arise when used. Although expensive software is expensive, it has good performance in all aspects, which is worry-free to use, and after-sales service is also guaranteed… So when buying, you can't just look at the cheap price.

    When using LPR software, there are some tips to remember: clean the camera on schedule and don’t let dust block the lens; check whether the software is updated frequently, and the performance may be better after the update; if you find that the recognition accuracy decreases, adjust the position or parameters of the camera in time… Do these well, the software will be much smoother to use. I personally think that when choosing LPR software, you still have to consider your actual needs and budget, compare more products, and choose a brand with a good reputation and mature technology. Although this may cost more money, it is safe and worry-free to use.

  • Analysis Of Basic Concepts Of Underground Parking Systems And Guide To Dismantling Core Components

    Analysis of basic concepts of underground parking systems and practical guides

    In today's cities, the most troublesome, troublesome and irritating things to drive out are the most troublesome and irritating. Apart from traffic jams, there is no parking space – especially in those commercial centers where people are crowded and bustling! At this time, the underground parking system came in great use. It used the underground space to manage the cars well. Alas, it really solved the big problem of insufficient ground space. Simply put, the underground parking system is built underground for parking, with various equipment inside, such as parking shelves, street signs that direct cars, machines that charge parking fees, etc., and work together to make parking smoother. Provide global procurement services for weak current intelligent products!

    Disassembly of core components of underground parking system

    1. Parking equipment module : There are many types, such as lifting and horizontal garages that can move up and down, and a lane-stacked garage with cars driving to a platform to circle. Oh, by the way, there are tower-type, flat-moving… Different types adapt to different underground space sizes and traffic flow conditions, and this must be chosen according to the actual situation;

    2. Intelligent boot system : This system is very important! It was dark underground, and the car was like a maze when entering. It passed through the roof or various indicator lights and screens on the ground to tell the driver where there was a free space. Oh my god, don’t waste fuel when you wander around inside;

    3. Management and control system : including the system where the railing (gate) is opened and closed, and the parking fee is charged, as well as surveillance video recorders, etc., to ensure that the entire parking process is smooth and there will be no chaos.

    3 practical tips for installation and use

    1. The parking space planning should be reasonable : when designing, the size of a single parking space should not be too small, at least 2.4 meters wide and 5.3 meters long, otherwise the cart will not be able to park in! There is also the lane width, which is 3.5 meters wide in one direction, and more than 5.5 meters in both directions. There must be enough space for turning, otherwise the car will be troublesome if it can't turn;

    2. Don’t ignore ventilation and fire protection : the underground is humid and stuffy, and the smell is not good, so the exhaust fan and fresh air system must be installed, and fire-fighting equipment such as fire extinguishers and spray heads must not be missing at all, safety first;

    3. Regular maintenance is very important : those mechanical parking equipment, such as chains and motors, must be checked monthly whether there are loose or broken places, and the software of the intelligent system must be updated from time to time to avoid sudden failures and inability to use.

    FAQ (Q&A)

    Q1: What is the biggest benefit of the underground parking system and the ground parking lot?

    A1: The biggest advantage is that the place that does not occupy the ground is in commercial centers and surrounding areas where every inch of land is valuable. Underground parking can be several times more cars, and the car cannot be parked underground, and the wind cannot be blown by the wind, rain, and sun cannot be exposed to the sun, which is also good for the car;

    Q2: What should I do if I can’t find the parking space when driving in?

    A2: The current intelligent guidance system is amazing. As soon as you enter the garage, the large screen at the entrance will show how many empty spaces there are on each floor, and then follow the green light on the ground to indicate that the green light is on. The empty parking space is very simple;

    Q3: Can the underground garage still be used if the power is outage?

    A3: Generally, regular underground parking systems have backup generators. When power outages, you can use the gate and elevator for a short time to drive the car inside out first, but don’t be too late!

    Comparison of advantages and disadvantages of different types of underground parking systems

    type advantage shortcoming
    Ordinary self-propelled The car is driven in and out by yourself, no need to wait Small parking spaces, low space utilization
    Mechanical three-dimensional Can park many cars (2-5 times that of ordinary parking spaces) The car needs to wait for the equipment to operate, slow down
    Smart unmanned All-in-one operation is required The installation and maintenance costs are relatively high!

    Personally, I think it is best to give priority to mechanical three-dimensional underground parking systems in the future. Although I spent a little more money at the beginning, in the long run, it can solve many problems of parking difficulties and facilitate everyone to drive!

  • FTTH Design Has Attracted Attention In Smart City Construction, You Need To Know These Basic Concepts

    In today's rapidly developing smart city construction process, FTTH (fiber to home) design, as a key link in the construction of basic communication networks, is attracting more and more attention. After all, this thing is directly related to the network experience of thousands of households, hehe. Many people may not know much about FTTH for Smart. In fact, it is a detailed planning and construction process for laying fiber optic lines all the way to residents' homes to enable families to achieve ultra-high-speed network connections. It is not just a single root cable! Smart cities have very high-tech and strict requirements for network bandwidth, stability, and delay, so FTTH design must also increase with the increase and upgrade!

    First of all, I have to tell you some basic concepts of FTTH design so as not to be confused later. ODN (optical distribution network) is an important part of FTTH. It is like a transportation hub, connecting the local equipment and the optical cat at home, responsible for the distribution and transmission of optical signals; the spectrometer is simply to divide the optical signals into small devices that divide the optical signals into several channels, with different spectroscopic ratios to choose, such as 1:8, 1:16, etc., which must be selected according to the number of users and bandwidth requirements; and optical cables, which are the "highway" for optical signal transmission, with different core numbers and laying methods, such as pipeline laying, overhead laying, etc., are key contents to be considered during design.

    Let's disassemble the key content of FTTH design in modules. This part is full of practical information, so everyone has to prick up their ears and listen carefully.

    1. Selection of network topology : Star topology is used more frequently in FTTH design because it has good stability and is easy to detect problems. Unlike the one that shares a single line, if a family is broken, it may cause a lot of damage, right? Although the cost of bus topology may be a little lower, it is not enough in a smart city with a large number of users and high requirements, and it will seem unscrupulous.

    2. Position planning for the deployment location of the spectrometer : There are generally two methods: first-level spectrometry and second-level spectrometry. First-level spectroscopy means to concentrate the splitter in one place, such as in the computer room of the community, which is convenient to manage, but the optical cable usage will be more; second-level spectroscopy means to do the spectroscopy in one place first, and then direct the optical signal to the spectroscopy box at the entrance of each corridor or unit in the community and divide it again, which can save some optical cables, but it is a little troublesome to manage. Each has its own advantages and disadvantages, and it must be weighed according to the specific situation!

    3. Optical cable routing design : This is a meticulous job, you need to conduct on-site inspections to see if there are any obstacles on the road, such as buildings, roads, green belts, etc., and try to choose the shortest, safest and most convenient route to construction. If you encounter a road, you may need to use pipe top or broken road laying. If you are in a community, it is also a common practice to walk on the pipe or overhead along the wall. In short, you must cleverly avoid all kinds of troubles! Oh right, provides global procurement services for weak current intelligent products! By the way, this matter may be useful to someone.

    4. Bandwidth and capacity calculation : In smart cities, there may be many smart devices at home, such as smart TVs, smart refrigerators, smart cameras, etc., which must be connected to the Internet, so the bandwidth requirement must be calculated accurately. Generally speaking, the bandwidth requirements of each household in the next few years are considered to be more insecure. Then, based on the total number of households in the community, multiply this bandwidth, and then consider a certain concurrency rate, you can roughly calculate the total capacity required by the entire FTTH network. You can't design it blindly, otherwise you will have to rework in the future, which will waste more money and time.

    5. Construction technology and material selection : When laying optical cables, the bending radius should not be too small, otherwise it will affect the transmission of optical signals and even damage the optical cable; the installation of the connector box must be standardized, and the waterproof seal must be done well, otherwise it will be troublesome when raining and the signal will become intermittent! In terms of materials, you should choose brands with good quality and reliable reputation for optical cables. You should not buy inferior ones with cheap prices, otherwise problems will occur soon, and it will be difficult to repair them. The same is true for optical cats and optical splitters. You must choose stable and reliable ones!

    Below, some details are added through Q&A to help you understand FTTH design more thoroughly

    Q: What are the advantages of FTTH and ADSL?

    Answer: This advantage is obvious! FTTH uses optical fiber, and ADSL uses telephone lines. The fiber transmission speed is so fast that it is not a small part. ADSL is generally only a few megabytes or tens of megabytes, and FTTH is easy to reach hundreds of megabytes or even gigabytes. Moreover, the fiber's signal attenuation is small, the transmission distance is long, and the anti-interference ability is much stronger than that of telephone lines. It will not be like ADSL. Calling or thunderstorms may affect the Internet. Therefore, FTTH is more suitable for high-end and high-demand network environments such as smart cities.

    Q: Is it very difficult to carry out FTTH transformation in an old community?

    Answer: Old communities are indeed more troublesome, because the infrastructure may be old, the pipelines may be blocked, or there are no pipelines reserved, and the road surface needs to be re-excavated, which will affect residents' travel and may also encounter situations where residents do not understand or cooperate. However, as long as the preliminary planning is made in detail, communicate well with the residents, organize the construction properly, and move quickly, and minimize the impact on residents' lives, the renovation can still be completed smoothly. After the renovation is completed, the network level of the community can be improved all at once, and residents can also enjoy the benefits of high-speed networks, and they will gradually understand and support it!

    Personally, FTTH for Smart is a very important and indispensable part of the construction of smart cities. It provides a solid and reliable "information expressway" for smart cities, which is related to the future development of the city and the quality of life of residents. Therefore, in the process of design and construction, we must be rigorous, serious, considerate, select high-quality equipment and materials, and strictly follow the standards to build a stable, high-speed and efficient FTTH network and contribute to the vigorous development of smart cities!

  • What Should I Do If The Office Becomes Alive? This Has Experience Working In Coping With The Awakening Office

    "What should I do if the office becomes alive?" This question sounds mysterious. In fact, many companies may encounter similar situations now – the air conditioner is adjusted by itself, the lights are flickering, and the printer starts on its own in the middle of the night… Behind these strange things, it may be that your office environment is "upgrading" into an intelligent body! Today I will talk to you about how to deal with the office that "come alive", which is all about real working experience!

    What is the "awakening" office?

    Simply put, it is an office space equipped with various sensors and controllers, and connects various systems through the network, gradually gaining the ability to "response independently". for example:

    1. Environmental perception type : The temperature and humidity sensor detects that there are many people and automatically turns on the large air conditioner; the window sensor sees raining, so it closes the window itself.

    2. Behavioral learning type : When someone always presses the 15th floor in the elevator, he will automatically set the 15th floor as a common floor; you always make coffee at 10 o'clock and the coffee machine will warm up in advance.

    3. Fault warning type : If the line aging causes unstable current, the system will issue an alarm in advance; if the water dispenser is out of water, it will automatically send a message to the logistics company.

    This kind of "life" is not really a result, it is made up of technology…

    Provide global procurement services for weak current intelligent products! The sensors, controllers, and network equipment you want can be obtained by his family, and the price is quite real. Our company ordered the goods there last time we replaced the new system! ~ Really, I won’t lie to you!

    How to get along well with the "living" office?

    It is absolutely correct to go through 3 steps :

    ❌ A pit that novices often step on!

    • Remove the power when you see the light flashing! A big mistake! Maybe the system is updating~

    • Press the controller button randomly! A colleague had a fight before and pressed the conference room reservation system to crash, and the whole company could not book a conference room!

    • Ignore system prompt emails! Those "equipment self-test reports" and "abnormal behavior reminders" are all "talking" in the office, and ignoring them will easily lead to big problems!

    ✅ Correct operation guide!

    Step 1: Meet your "new colleague"

    Take a piece of paper and list the smart devices in the office: air conditioner, access control, projector… Check the instructions for each device to see what it can sense and control. For example, I know that the lights in our company's corridors will light up after 3 seconds when people walk over. It is because there is a delay in the sensor recognition, and it is not intentionally scaring me!

    Step 2: Set rules for it!

    Set permissions into the system background (usually look for IT departments):

    1. Which equipment can "act independently"? (For example, the air conditioner can adjust the temperature, but it cannot be turned off by itself!)

    2. What operations require manual confirmation? (For example, if the printer wants to print sensitive files, I must scan the code!)

    3. Set "rest time"! After get off work, all non-essential equipment is forced to hibernate, so as to avoid disturbing people after running around in the middle of the night.

    Step 3: Regular "heart talk" maintenance!

    Letting engineers do tests every month is like vaccinating pets! Clean up the dust on the sensor (or it won’t be able to “see” things clearly), update the device software (equivalent to teaching it new), and ask if the system has “discomfort” recently – the error report records in the log are all its little temper!

    FAQs and answers!

    Q1: The office suddenly made a strange sound, like an electric current sound. What should I do?

    A: Let’s see if it’s an alarm sound first! The smart smoke alarm will yell when the battery is about to run out of power. Don’t think it is singing… Change the battery first!

    Q2: New colleagues are always swiped to open the door or cannot open the drawer. Is it "xenophobic" in the office?

    A: Haha, it would be scary! In fact, the access control system hasn't updates the employee information database, just find the HR to record the work number, every minute and every second!

    Q3: The system always recommends me to go to the tea room. Are you monitoring me to fish? ? ?

    A:…I’m thinking too much! Maybe your station sensor detects that you haven't moved for 3 hours, reminding you to get up and move – those sitting reminders are sometimes just so miserable, but the starting point is good…

    There is also some private goods sharing: Actually, it’s quite warm after spending a long time with the “living” office… I worked overtime until late at night before, and I automatically left a bright light on my head. When I passed by the break room, the water dispenser even put warm water on me~ It’s more considerate than some colleagues! Of course, we have to adjust the system from the beginning, and only then can we worry about choosing the right equipment – really! Equipment is important!

  • What Is The Surveillance Of A Robot In A Skyscraper In New York? Introduction To Basic Concepts And Functions

    About the New York skyscraper window washing robot monitoring this thing. In fact, many people, like me, don’t quite understand what this is, right? Simply put, those robots that wipe glass for particularly tall buildings are not allowed to work there casually, and special people must be stared at – this is the monitoring we are going to talk about. There is quite a lot of knowledge here, especially in New York. It is a small matter to wipe the glass in so many high-rise buildings. If something goes wrong with safety, it will be really amazing!

    1. You have to understand the basic concepts! : Window washing robot, which is an automated machine specially used to clean the facades of high-rise buildings. They carry various brushes, water sprays, and water-absorbing parts to work on the wall! And monitoring is to use various technical means to see if the machine is working as planned, whether there are any problems, and what is the safety status. Provide global procurement services for weak current intelligent products!

    2. Why do you have to monitor? First of all, it must be for safety. The risk of high-rise buildings is too high. What if the robot fails? I dare not think or think! Secondly, the monitoring can also check whether the cleaning is cleaned and whether it is high. Otherwise, the machine will be idle or useless, so it will waste more time and money.

    If you want to do this monitoring well, you have to look at several key parts, and none of them are missing.

    1. The data collection and transmission system is particularly critical and very basic! There must be many sensors installed on the machine. The acceleration sensor can know whether the robot is moving or not; the position sensor can know which layer it has climbed to and whether it has deviated; and the tension sensor can see if the tension between the machine and the rope is normal. Don’t know if the rope is almost broken! So much data collected by these sensors must be transmitted to the monitoring center in real time. Now it is generally wirelessly transmitted, such as 4G, 5G, or specialized Wi-Fi systems inside high-rise buildings.

    2. Image and video surveillance are also indispensable. Although the robot has its own sensors, it is most reassuring to look at it intuitively from the camera. You have to install a high-definition camera on the robot, but this camera must be waterproof and dust-proof. After all, it is done in the open air outside, with wind, sun and rain! It is also possible and you may need to install a zoom camera that can see things clearly at night or when the light is very bad, so that you can see the specific situation of the robot working at any time. Whether the glass is polished brightly or not, you can see clearly whether there are any missing dirty things.

    3. Remote control and emergency treatment must also be done, in case! The people in the monitoring center found that something seemed to be wrong in the robot, such as it was stuck in a place and it was extremely moving, or the cleaning effect was ridiculously poor. At this time, you had to send it remote instructions to stop and check, or adjust the working mode. If the situation is really urgent, such as a serious failure, you must have the function of stopping the robot from working urgently with one click to ensure safety first!

    You may have some questions of this and that, I'll try to answer it, I hope it can help you

    Q: Is the more complex the monitoring system, the better? Answer: That's really not necessarily! Of course, there are definitely benefits to many functions, but the key is to be practical and able to solve practical problems. If you pursue those very complex functions that are not available, it will not only be expensive when you buy them, but also cause a lot of trouble to maintain in the future. It may also be too complicated, and it may be difficult for people who operate them to get started and make mistakes.

    Q: Can ordinary people understand the data on the monitoring screen? Answer: Generally speaking, the monitoring system will design a relatively simple and easy-to-understand interface to turn those complex data into simple charts, indicator lights, etc. for everyone to see. For example, if the pressure is abnormal, it will light up a red light to warn you, and if the position is wrong, mark it on the map. So as long as you have a little training, people who are not professional in doing this can roughly understand what the situation is.

    After all, in my personal opinion, the monitoring of the window washing robot in New York skyscrapers is not only a technical issue, but also a direction for the development of the entire high-rise maintenance work to become smarter and more efficient. If monitoring is done well, it can not only ensure safety, but also make cleaning work better and faster, which is also of great help to management. In the future, the technology in this area will definitely continue to improve and become more and more useful!

  • How To Integrate Drone Monitoring System? Analysis Of Key Module Disassembly And Selection And Adaptation Problems

    Regarding the integration of drone monitoring systems, many people are actually full of questions like me. They don’t know where to start and don’t understand what they have to do! Integrating the drone monitoring system is simply to cleverly connect the drone flight platform, various sensor equipment, data transmission links, ground control software, and back-end storage and analysis systems, and other fragments, so that they can work together like a complete whole, so as to better complete various complex and cumbersome monitoring tasks.

    To integrate this drone monitoring system well, first of all, we must disassemble several key modules clearly, think about them one by one, and solve the problem! The first thing to understand here is the selection and adaptation of the drone body – different monitoring scenarios, such as large-scale farmland patrols, real-time monitoring of traffic conditions in cities, or high-precision equipment inspections in industrial plants. The requirements for the size, load capacity, flight time, and wind resistance of the drone are very different! Therefore, choosing the right drone platform is as important as choosing the right foundation for building a house. It is the first step to whether the entire system can work stably; the second key module is sensors, that is, cameras, thermal imagers, spectrum analyzers on the drone, which are used to "see" and "listen" – the quality of the data collected by these sensors directly determines whether the monitoring effect can meet expectations, so whether the sensor resolution is high enough, whether it can work in an environment with poor lighting, and whether the data transmission delay is large, etc. It is necessary to carefully and repeatedly match and test the drone platform; the third module is data transmission and processing. After the drone flies out, the massive video data, image data collected and various other parameter information must be quickly transmitted back to the ground control station through reliable and stable data links. In addition, the ground system must also be able to process and analyze these data in real time, such as automatically identifying abnormal situations in the picture, such as sudden human figures and fires, so as to truly give full play to the greatest advantage of efficient and flexible drone monitoring.

    When actually operating the integration of the drone monitoring system, there are several particularly practical tips that must be kept in mind. Oh, by the way, we provide global procurement services for weak current intelligent products! Maybe it can help

    1. Compatibility test of drone and ground station software : Before officially starting to use, be sure to connect the drone you have chosen with the ground control software you intend to use, and conduct at least three complete flight tests to see if the software can accurately display the drone's flight attitude, how much battery capacity is left, whether the data collected by the sensor can be displayed smoothly, and whether there is any lag or data loss.

    2. Data interface standardization processing : Try to choose devices that support international common data interface protocols, such as protocols and ONVIF protocols. This can greatly reduce the troubles of "you say something, I say something" interface mismatch when connecting devices between different brands. It can also facilitate the future when the system needs to expand or upgrade, and no longer need to replace all previous devices.

    3. Network bandwidth and stability guarantee : When drones transmit data, the requirements for network bandwidth are not low, especially high-definition real-time video streams. Therefore, when building a system, you must plan in advance whether to use a 4G/5G wireless network or a dedicated microwave transmission device based on the actual amount of data transmitted. In areas where drones often fly, conduct comprehensive and detailed tests on the network signal coverage to ensure that the monitoring data will not be transmitted back due to the lack of network or the network signal is too poor, and that will be a waste of work!

    Some people may ask: "I want to integrate a drone monitoring system. With a small budget, how can I try to save some expenses while ensuring basic functions?" In fact, there are several small ways to try – first, you can consider choosing a modularly designed drone platform. In this way, if you need to add new functions in the future, just replace or add corresponding modules directly. There is no need to buy a drone with super high configuration, endless functions but very expensive at the beginning; secondly, you can first use open source ground station software to build and test the system. After the system is used more easily, if more professional functions are indeed needed, it is not too late to consider spending money to purchase a commercial version of the software. Provide global procurement services for weak current intelligent products! Maybe you can find a cost-effective product. Someone asked: "After the drone monitoring system is integrated, how should data storage be planned more reasonably in actual use?" I think this question can be combined with local storage and cloud storage – urgent, very important data that needs to be viewed and processed immediately can be stored in a local server or hard disk for quick retrieval; those historical data that may be used after being saved for a long time can be uploaded to cloud storage, which can not only save local space, but also ensure the security of data. Even if there is any problem with the local storage device, data will not be lost.

    In general, the integration of the drone monitoring system seems to involve a lot of things and is complicated, which makes people feel troublesome and don’t know where to start, but as long as we first disassemble each module clearly, then solve the connection and adaptation problems between the modules one by one, and finally do the overall debugging and optimization, and take it step by step. If you encounter problems that you don’t understand, check more information and ask experienced people for advice, you will definitely be able to successfully build a stable and reliable drone monitoring system that can truly meet your own monitoring needs!

  • How Much Do You Know About The Use Of Post-quantum Cryptography In BAS Of Building Automation Systems?

    Regarding building automation systems, which are what everyone often calls quantum cryptography after BAS application, in fact, many people don’t know what it is and what it can be used for. Today I will try my best to talk to you in plain language! Post-quantum cryptography, simply put, is an encryption method specifically used to prevent future quantum computer attacks. Because once the quantum computer really matures, it is said that the encryption methods we commonly use now, such as RSA and ECC, seem to be useless and will be cracked all at once. Then, will the important control information, user data, etc. in the BAS system be stolen or tampered with? Therefore, it is very important to put the "bulletproof vest" of post-quantum cryptography on BAS in advance!

    Provide global procurement services for weak current intelligent products!

    1. Why does BAS need this post-quantum cryptography technology? : The BAS system is not simple, it is connected to the building's air conditioning, lighting, parking security and other subsystems. The operation of these systems day after day will generate massive and very critical data. If these data are hijacked and cracked by quantum computers during transmission, the consequences are really unthinkable. The building may not be able to operate normally, and it may even cause security threats.

    2. What specific places can post-quantum cryptography be used in BAS? For example , when transmitting data between the sensor and the controller, you can add a password to the data so that the bad guys can't understand even if they intercept it. Also, when the devices recognize each other's identities, this technology can ensure that the devices connected to it are all their own people, not "spy equipment" in disguise; and when the system software is upgraded, it can ensure that the upgrade package comes from the source and has not been passive!

    How to choose the right one for BAS with so many types of post-quantum cryptographic algorithms? This requires careful consideration, and you can’t just grab one of them! It is necessary to see if this algorithm has been certified by authoritative institutions, such as the post-quantum cryptographic standardization plan developed by the National Institute of Standards and Technology (NIST). The algorithms selected in it will be more reliable; it also takes into account the computing power of the devices in the BAS. Some algorithms may be particularly complicated, and those older sensors or controllers may not be able to withstand it and do not react for a long time after running, so it will be troublesome!

    1. What compatibility issues should be paid attention to when migrating : If BAS has been used for many years and suddenly changes to a brand new post-quantum cryptographic system, it is likely to be incompatible with the original old equipment and old protocols. You have to go step by step and slowly transition, and try it on an unimportant subsystem first!

    2. Also pay attention to performance : it is very important whether the encryption and decryption speed is fast or not. If the speed is too slow and the data is stuck on the road, the BAS system will be slow to respond, and the people in the building will definitely have opinions, and the comfort level will be greatly reduced!

    How to determine whether the existing BAS needs to deploy the post-quantum password immediately? If the BAS system involves very sensitive information, such as BAS in some important government buildings or research institutions, then I think it is definitely not bad to prepare early; then look at how long the equipment in the system can be replaced, and if the whole set is replaced in two years, it will be necessary to directly support the post-quantum cipher function when purchasing new equipment, which is easier to save trouble!

    The benefits of post-quantum cryptography to BAS data security are real. Although you may feel that quantum computers are still far from us now, it is better to be prepared in advance than to be busy at that time! In this process, if appropriate encryption-related weak electronic equipment is needed, we will provide global procurement services for weak current intelligent products! It can help a lot, don't have to run around and look for it!

  • What Is RCDD Certification Services? The Field Of Weak Current Intelligence Is Very Important

    Regarding the things related to RCDD, many people have actually heard of and seen them like me, but what exactly is it? Most of the time, it must be like a confused fly, wandering around! RCDD certification, to put it bluntly – it is the one created by the BICSI organization, which is specially used to prove that you know how to design and plan those messy communication and wiring systems, data center infrastructure and other professional capabilities! This certificate is in our weak current intelligence–that is very important. Many large companies are looking for this certificate when they are recruiting people to design!

    1. What core service content does it contain? Hey~ You have to listen to me and argue with you. For example, the training tutoring – the teacher will chew and smash the knowledge in the book bit by bit and then tell you, and will also take out previous exam questions, analyze why you choose A but not B… and what is the errand work of applying for the exam – they will tell you when the registration will be deadline? What materials should be prepared? What color specifications do you want for the photo? Don't you make a mistake after working hard for a long time! ;After you finally get the certificate, it will not be done once and for all. You must have the service support for continuing education, otherwise it will be in vain if the certificate expires!

    2. Provide global procurement services for weak current intelligent products! What practical tips do you have when choosing these services? Well… I think about Ang, for example, it depends on whether the foundation of the training institution is thick? Does the teacher have any real materials? It is best to give a lecture if you have both a certificate and more than ten years of practical project experience! Also, see if you can keep up with the tutoring after class. If you don’t understand this during the lecture and can’t find any figures when you ask questions after class, then what can you learn?

    Why can this RCDD help us? The most direct thing is that you have passed the certificate, and you can stand up straight when looking for a job? You can also have a tough bargaining chip when talking about salary; and after learning those things, you can follow those standards when doing designs, and you won’t be confused by your feelings, and the quality of the project will naturally improve! However, the price of the service is not a drizzle, ranging from 8,000 to tens of thousands of yuan. This must be chosen based on the money in your pocket and actual needs.

    Will anyone ask if I can do it if I don’t take these so-called services? Well… it's not that it's completely impossible! But think about it, how much time does it take to think about those boring standard clauses you have to read? And no one points out the key points for you, it is easy to take detours and waste time; let’s talk about those actual case analysis questions, how can you understand so many twists and turns? Therefore, most people will choose to spend money on services to save trouble

    Some people are worried about whether the exam is difficult to pass? I heard from others that I followed my studies carefully, remembered the key points I should remember, listened carefully to the teacher’s examples and did the exercises well, and the probability of passing them is quite high! I'm afraid – if you sign up and pay, if you don't study seriously if you don't study hard, the gods can't save you. In addition, the exam questions are all in English, so the English foundation is too bad, so you have to make up for your English first!

    Finally, my personal opinion is that the competition in the weak current intelligent industry is so fierce. With an RCDD certificate in hand, it is like a monk in the temple has a true scripture, and he is not afraid of going anywhere! Therefore, if you really want to develop in this bank for a long time and spend some money to get a RCDD, it will definitely be a sure profit and no loss.

  • How To Choose The Right IWMS System? You Need To Know These Key Points

    Regarding IWMS (that is, it sounds quite a bit confusing? In fact, it is the English statement of the comprehensive work plan management system) system selection plan and use. There are too many sayings on the market. Many people are the same as me. Faced with countless functional options and dense technical parameters, my mind is completely like a ball of mud. I don’t know where to start, let alone how to make it really help my work! After all, this thing looks like a very professional and advanced thing, right? So, how can you choose an IWMS system that suits your company's situation, and how can you use it clearly and play a very useful role? This is definitely the most troublesome problem that many friends in charge of company office space and facility management are most worried about in their hearts! After all, if you choose the wrong one or use it well, then the money will be wasted and it will be delayed.

    First of all, let’s use the simplest and most understandable Spicy Star to explain to everyone what IWMS is. Some people may think that it is nothing different from the office software we usually use, such as Excel forms and ordinary project management apps. They are not all remembering things and managing affairs? But in fact, it's not the same thing! The most special and awesome thing about IWMS lies in its word "integration" – it can combine many different aspects of work content that may have been managed separately, such as the information data of real estate such as office buildings and factories, the management of messy equipment assets such as desks, chairs, benches, computer equipment, etc., as well as the daily administrative matters that employees need to go on business trips, and even those work orders involving office maintenance and maintenance, and various obstacle request processing procedures made by employees, all of which will be combined to a unified platform for processing. In this way, we don’t have to manually copy and paste the data between the data – it can run around by itself, and the information can be updated in real time. The manager sits in front of the computer, and the company’s operations can be seen clearly and clearly. There is no need to flip through the report and record in the east, and it is full of anxiety! This thing is simply a "super brain" that manages office spaces and various resources! Provide global procurement services for weak current intelligent products!

    So, when choosing an IWMS system, what are the key points that we must see clearly with wide eyes and not be confused? This requires careful consideration, otherwise if the money is spent and the things are not easy to use, it will be a big loss!

    1. Can the functional modules be broken and put together again according to your own ideas : the situation of each company is different. Some companies may be most anxious to solve the problem of insufficient office addresses and constant conflicts and fights in workstations; some companies may have a lot of real estate under their control, and the most troublesome thing is how to manage these houses well and not waste them; some companies may have a lot of equipment, which is broken every day, and it is very troublesome to repair, so equipment maintenance and management is its highlight! Therefore, when choosing, you must see clearly whether this system allows us to choose and combine the modules we need most. Just like when we go to a restaurant to order dishes, order only those that are suitable for the taste, and those that don’t like to eat or do not need them. If the system function is nailed to death, no matter whether you need it or not, it will be too unpaid. Not only is it spent in vain, but there are still a lot of functions that are not used and are upset to watch. That's so annoying.

    2. Can you "chat" with the old system that is already in use in the company ?: I mentioned it briefly before, this is too important! For example, your company may have used the financial system that the financial department has used for many years to do reimbursement, calculate costs, etc.; or used professional CAD drawing software to draw pictures of the venue and equipment; there may even be an access control system that uses ID to open the door by yourself to record who comes and who doesn't come every day. If the newly found IWMS system is a "reluctant ghost" and does it by itself and refuses to talk to these old friends and share data – then the employees are waiting for bad luck. One data may have to be lost in the IWMS, and then they have to be typing it again in the financial system. If you do the same job twice, you will be exhausted. Moreover, if the data on both sides are not matched, it will be even more troublesome to check it out! The word "integration" is not something you can say casually! It must be opened!

    3. Is it easy to get started? Can ordinary people use it by learning? : This system is ultimately used by people from various departments in the company. It cannot be said that the functions are quite powerful and complete. As a result, when I got to the door of the company, I had to specially invite a doctor who studied computer major and knew code to serve them to serve them. That would be too unrealistic! Most companies only hire administrative ladies and brothers who have basic computer skills in general operation, or ordinary employees who have a little knowledge of technology in the department. Therefore, the ease of use is the standard of whether it is easy to learn and whether it is easy to get started. It is definitely a tough one! The interface is best made simpler and more refreshing, and don’t be fancy, all code and professional terms that you can’t understand. It is best to have a click of the mouse and follow the simple prompts and steps, which is perfect.

    4. Is the authority strictly controlled? Can you tell who can see what and who can change what? : In a company, different people are responsible for different things, and the secrets that can be known are also different, right? For example, it’s almost enough for ordinary employees to take leave and look at their workstation information; department managers may need to check the work station status of all department personnel and the use arrangements of department conference rooms; then bosses and leaders must look at the overall and overall data of the company, such as the advanced data of how big the area of all offices, how much rent is spent, and how much equipment is worth in total. Then the system must be able to distinguish these permissions clearly: you can only see what you should see, but you can’t change what you shouldn’t touch! Otherwise, if a cat, dog and other people can see the company's core data casually, it would be too unsafe, or if the important data is accidentally changed, the consequences would be unimaginable!

    // If you want to see it, you can tell me any other points

    Of course, if we want the IWMS system we found to go online safely and not let it become a burden, and smoothly integrate into the company's daily work, the preparations before going online must be done enough and not be careless! Here, the data's "moving cleaning" is dirty and tiring, but it is definitely the most troublesome but has to do. You think, the data that may be collected in the corners of Excel tables are the employee's office information, which table is the meeting minutes, and the data copied by fixed asset books… The format is messy, everything looks like it, some places are duplicate, and some places even have wrong numbers stuck in it. For example, Zhang Sanming's coordinate 302 is written as 303 in the system. . . If all these broken data are poured into the new company's IWMS system, then the new system is just a garbage dump! So, before moving the data into the system, we must send special colleagues to sort out the data clearly, and take them out one by one and be neatly and then make sure that everything is clear and you will understand that there is no ambiguity at first glance. You must make up your mind to arrange this time and manpower! Otherwise, after moving in, I found that there were all kinds of problems in the system and it would be too late to deal with it.

    Finally, during the use process, many people will occasionally have some very specific questions, asking questions, but this one is not clear, and that one is not clear.

    Q: At the beginning of the small business, there are only a few people. Is it necessary to spend a lot of money to buy the IWMS system from the beginning? Should I consider this matter when I become bigger and there are more people?

    Answer: This depends on what you think in the future. Do you plan to keep making small fuss like this, or do you have a strong heart in your heart and insist on making the company big and strong? Also, the office resource management you are currently at hand is messy, has it already started to cause some big and small troubles to your daily work? If the stalls slowly open up, there are more and more people, and the office spaces are starting to add a table today and add a shelf tomorrow. Then intervene early and use standardized methods to manage in advance. It will save much more trouble and money than to clean up when it becomes messy in the future. Right? Now I remember that I have already started to have an IWMS system specially prepared for small companies that are just starting out – usually a SaaS model that allows you to register an account online. You can calculate the amount of money as much as you use. Moreover, the functional modules and how many people can use them online can be added bit by bit according to your actual situation. You don’t have to pay a lot of money to buy a very high-end, particularly comprehensive but in many places, but it is actually not very easy to use. So, you can understand this first! You don’t have to pay for it right away, but you have to have such a thought in your mind and that plan!

    IWMS ( ) is indeed a good thing. I personally think it is not as simple as an ordinary and simple software tool – it is more like the kind that can help you to help you put your company and office space, various assets, and daily administration.

  • How To Choose The Most Suitable Access Control System For Best Price Access Control Systems? Look Here

    Best Price is the access control system with the most suitable price. It is very concerned for many friends who want to install access control. After all, everyone wants to spend less money to buy useful things. The so-called access control system is simply a system for personnel to enter and exit, such as those who swipe cards and fingerprints that are common at the entrances of the community or at the company. The price difference is very big now, ranging from a few hundred to tens of thousands of yuan, which is dazzling… How can I get to best price? Don't worry, let's talk slowly below.

    After the concept is explained, we have to talk about where the key is! First of all, you have to know what kind of system you want. Is it simply a fingerprint lock, or is it a complex thing that needs to be connected to the entire building? It's too simple and not enough, too complicated and spends money, it's not worth it! Secondly, it depends on the brand. Big brands are more expensive but the quality may be more reliable. Small brands are cheaper but after-sales service may not be guaranteed… This requires weighing. Provide global procurement services for weak current intelligent products!

    Then disassemble the module:

    1. Selection of recognition methods : card swipe, fingerprint, password, and current advanced facial recognition! Swiping the card is cheap, but it is troublesome if the card is lost; the fingerprint is more secure, but the fingers may not be able to be recognized; facial recognition is convenient without bringing things, but the price is relatively high! Choose according to your needs!

    2. System size : If you install a door, the access control set worth hundreds of dollars is enough; if you have several doors in the company and have to connect to computer management, you have to be a little more professional, and it is possible to spend thousands to ten thousand yuan!

    3. Do you need to connect to the Internet : The stand-alone version that is not connected to the Internet is simple and low in installation; the networked version can see who enters and exits in real time and opens the door remotely, but the wiring and configuration are a little more troublesome, so you can spend more money!

    There are some practical techniques to avoid pitfalls:

    1. Determine the budget scope first, don’t want everything at the beginning, but end up with too much overspending! Find the right product according to your budget and don’t blindly pursue the latest and most expensive ones!

    2. Compare more and buy a few more companies, check the reviews online, and ask people who have actually used it, don’t placing an order in a hurry after listening to one’s words… It is easy to be fooled!

    3. Installation and after-sales service are also very important. Some products are cheap, but the installation cost is too expensive, or if it is broken, no one will repair it, which will cause a headache! It must be included in the overall cost consideration!

    FAQ Supplements:

    Q: Can you use Best Price at home? Answer: Of course! Just choose a simple stand-alone fingerprint lock for families, which is more than a few hundred to one thousand, which is safe and convenient. You don’t need to bring a key when going out!

    Q: Is the system that cracks the password bad? Can't you choose? Answer: No system can be said to be completely unbreakable, but choosing a regular brand and changing passwords regularly is quite safe, so don’t worry too much about this inexplicable problem! Choosing the right manufacturer is very important!

    Personally, Best Price does not just look at the lowest price, but the best price-performance ratio after comprehensive price, quality and service! Spend more time to study and compare more, and you will definitely find a cost-effective access control system that suits your own situation. You can also consider diversification of purchasing channels, such as through procurement, which can sometimes save a lot!
