Monitor frequent lens initialization
From a technical perspective, video monitoring system development is divided into the first generation analog video surveillance system (CCTV), the second generation is based on "PC + multimedia card" (DVR), digital video surveillance system to the third generation completely based on IP network video surveillance system (IPVS).
From the earliest simulation monitoring to the previous years of the red-hot digital surveillance and now the network video monitoring, there has been a dramatic change. As IP technology has been gradually consolidated around the world today, we need to relearn the history of video monitoring systems.
The monitoring system is one of the most widely used systems in the system. Now, the more suitable site monitoring system is the handheld video communication equipment, and video monitoring is the mainstream.
