What is the difference between a network video surveillance system and a traditional video surveillance system?

There are two mainstream network video surveillance products, network video server (DVS) and network camera (IPCAM).

Traditional closed-circuit surveillance systems (including DVR-based area surveillance systems) use video cables or optical fibers to transmit analog video signals, are very sensitive to distance, and are not economically convenient for long-distance transmission across regions (compared to network video surveillance systems) -Network video surveillance), generally centralized monitoring in local areas, long-distance transmission generally adopts point-to-point networking, the entire system has large wiring projects, complex structure, high power consumption, high cost, and needs multiple people on duty The entire system management is less open and intelligent.

The network video surveillance system adopts a flexible rental method (mainly using IP broadband network). Multiple users can share a central control platform. User input and use are simple. Users can browse and control remotely. In principle, any place where Internet access is available Can browse and control. It also introduces many new digital technology achievements (such as image recognition technology), which makes up for the deficiencies of traditional video surveillance systems, provides value-added business capabilities, expands functions and scope, and improves system performance and intelligence.
