Five major issues to be addressed in the popularization and development of explosion-proof high-definition video surveillance

In the current explosion-proof video surveillance market, explosion-proof high-definition video surveillance has become the mainstream trend, but several major problems faced by explosion-proof high-definition video surveillance also urgently need to be solved. In terms of transmission and storage, system integrators can solve the problem of high cost investment; In terms of display and management, high-definition manufacturers need to invest some effort in improving the underlying software and hardware; The investment in improving night vision is relatively small, and it is also the easiest solution to improve user satisfaction. Compared to standard definition explosion-proof video surveillance, the advantages of high-definition network surveillance are very obvious. However, through market promotion in recent years, the following five major problems will still be encountered in the popularization of explosion-proof high-definition video surveillance. Let's take a look at these five major problems and their solutions together with Shiguo Technology!
1. Transmission issues:
Explosion proof high-definition network cameras usually use 720P or 1080P solutions. To achieve ideal image effects, a network bandwidth of 2-8M is required. If there are hundreds of points in a system, the data flow of the entire network will be quite large, and the video flow is real-time, which will continue to cause continuous pressure on network related switching devices. This requires sufficient work in network planning. Currently, due to the continuous reduction of fiber optic cable costs, local local area networks can fully use fiber optic and high-performance switches to form high-speed networks. With the popularization of broadband networks, the ultimate result of optical access and copper retreat is the low-cost high-speed internet. It no longer takes too long for remote explosion-proof high-definition video image transmission.
2. Storage issues:
Transmission has raised the issue of large data streams. If data is aggregated to the center or various nodes for storage, it poses a significant challenge to the bandwidth pressure and storage capacity at the center entrance. At present, heavy investment can only be made in IPSAN and storage media. It is best to use an embedded architecture for IPSAN, with many fewer boards and high stability. However, the disadvantage is poor compatibility and less flexibility in secondary development. Most NVR products on the market are based on the X86 architecture, which means adding an array card to the server, installing application software, and combining the server and disk array, resulting in better compatibility. If IPSAN is adopted, the storage medium needs to use enterprise level hard drives in order to leverage IPSAN's advantages in data storage speed and security. For some small and medium-sized systems, if the storage time is not required to be too long and the data security requirements are not too high, it is possible to use mainstream servers in the market to complete the storage function.
