Monitoring system is one of the most widely used security systems. At present, the most suitable field monitoring system on the market is hand-held video communication equipment, and video monitoring is the mainstream now. From the earliest analog monitoring to the fiery digital monitoring in previous years, and then to the emerging network video monitoring, earth-shaking changes have taken place. Today, with the gradual unification of global IP technology, it is necessary for us to re-understand the development history of video surveillance system. From the technical point of view, the development of video surveillance system can be divided into the first generation analog video surveillance system, the second generation digital video surveillance system based on multimedia card and the third generation video surveillance system based on IP network.
