What is the difference between closed-circuit monitoring and network monitoring?
Network video monitoring system of information flows and the full digital and independent of each other, the design concept of hardware and software using modular and the scale of the system, the equipment configuration has the versatility, openness, flexible system configuration, control function is perfect, convenient data processing, convenient use and installation system and the advantages of simple debugging and maintenance. At the same time, IP, digital products will lead to large-scale cost advantages.
Network video monitoring system used for flexible (mainly by IP broadband network), multiple users can share a set of center control platform, user input, easy to use, users can browse and remote control, any Internet where principle can browse and control. It also introduces many new technologies (such as digital image recognition technology), to make up for the lack of traditional video surveillance system, provides the value-added service ability, expands the function and scope, improving the performance and intelligent system.
The traditional closed-circuit monitoring system (including regional monitoring system based on DVR) using video cable or fiber optic transmission of analog video signal, is very sensitive to the distance, and cross regional long distance transmission is not convenience (compared to the network video monitoring system and network video surveillance), general local area centralized monitoring, remote transmission generally uses point-to-point way to network cabling project, the whole system of large, complex structure, high power consumption, high cost, need more people on duty; the whole system of open type and low intelligence.
