In the current security field, IP surveillance systems are gradually becoming the mainstream choice. Compared with traditional analog systems, it is based on the network, achieves digital collection of video data, completes digital transmission of video data, and performs video data storage and management. This not only means higher image clarity and a more flexible deployment form, it also represents a comprehensive solution that integrates intelligent analysis capabilities, remote access capabilities, and system integration capabilities. Knowing its core components, advantages, and key points in the actual deployment phase is very important for any individual or enterprise thinking about upgrading or building a new security system.
What is the working principle of IP surveillance system
The key to the IP surveillance system is to convert video signals directly into digital data. After the image sensor in the camera captures the image, the chip performs compression encoding, and then uses a network protocol (such as TCP/IP) to transmit the data packet through the LAN or the Internet. Users can use computers, mobile phones or video management software to view or play back recordings in real time from anywhere in the world with authorization.
The entire system infrastructure is built using standard network equipment, such as switches, routers and network cables, which shows that it can be seamlessly integrated with existing IT facilities, thus simplifying the wiring project. Video data is often stored in network hard disk recorders or dedicated storage servers. It supports efficient and fast retrieval and backup based on time, events, etc., which brings great convenience to subsequent verification.
What is better about IP monitoring than analog monitoring?
The most prominent among the significant advantages is image quality. IP cameras widely support 720P, 1080P and even 4K resolutions, which can provide clear and delicate details, which is particularly important for identifying more critical information such as faces and license plates. Analog cameras are limited by old standards, so their clarity is often difficult to meet the refined management needs of modern security.
The second focus is on functionality and scalability. The IP system can support wide dynamic range and strong light suppression, as well as intelligent analysis, advanced functions such as area intrusion and people counting. The system is very convenient to expand. It only requires connecting new cameras to the network and configuring IP addresses. There is no need to replace core equipment. This flexibility lays the foundation for the continuous evolution of the security system.
How to choose the right IP surveillance camera
When selecting a camera, you must first clearly monitor the scene. For indoor fixed locations, you can choose a dome camera, which has a more concealed appearance. Outdoors or in areas that require zoom tracking, you must choose a barrel camera or ball camera with infrared fill light and proper rectification. As for key locations such as entrances and exits, you should consider a dedicated model with a face capture function.
The surveillance field of view and distance are determined by the focal length of the lens. A 2.8mm lens is suitable for large-scale surveillance situations such as a hall, while a telephoto focal length of 6mm and above is suitable for viewing details such as a cashier. In addition, the camera's encoding format such as H.265 can greatly save storage space, the waterproof and dustproof level requires IP67 or above for outdoor use, and whether it supports PoE power supply to simplify wiring. These aspects need to be paid attention to.
What should you pay attention to when installing an IP surveillance system?
The stability of the video stream needs to be guaranteed, especially when multiple high-definition videos are transmitted simultaneously. The surveillance network must have enough bandwidth to carry it. For this reason, network planning has become a top priority. It is recommended to use a Gigabit switch and divide it into independent VLANs to avoid interference with the office network.
Power supply is critical, as is installation stability. Using PoE, a network cable power supply method, can reduce power wiring, but it is necessary to calculate whether the total power supply of the switch can meet the needs of all cameras. The installation position should prevent the lens from facing strong light, and ensure that the bracket is firm to prevent the screen from shaking due to wind and losing its monitoring significance. Professional installation is the guarantee for reliable operation of the system. Provide global procurement services for weak current intelligent products!
How to choose the storage solution for IP surveillance system
To accurately calculate storage capacity, it must be determined based on the number of cameras, resolution, frame rate, and expected storage days. Generally speaking, if a 1080P camera records all day long, its daily capacity will be in the range of 20GB to 40GB. Using H.265 encoding can save approximately 50% of storage space compared to the old standard.
There are two mainstream storage architecture options, one is distributed storage, that is, each NVR implements storage locally, and the other is centralized storage, which is connected to a central storage server for storage. For small and medium-sized systems, NVR solutions are simple and economical; for large-scale networking projects, centralized storage is more convenient in terms of management and maintenance. In addition, consider using a RAID disk array or cloud backup strategy to avoid data loss due to hard drive damage.
What is the development trend of IP surveillance technology in the future?
The clear direction is the deep integration of artificial intelligence. The future system will not only record, but also actively understand the content of the screen, and implement advanced functions such as behavioral analysis, abnormal event warning, and image search. It will transform security from post-retrospective to pre-emptive prevention, greatly improving active defense capabilities.
The system will become more open and integrated. With the help of standard protocols such as ONVIF, the IP surveillance system can be more conveniently linked with subsystems such as access control, alarm, and fire protection, thereby building a unified intelligent security management platform. At the same time, network security will be raised to unprecedented heights, and related capabilities such as equipment authentication, data encryption, and anti-intrusion will become basic requirements for products.
When you start planning your own IP surveillance system, will the most priority factor you consider focus on cost control, clarity of image presentation, ease of use of the system, or focus on future intelligent expansion potential?
