The monitoring system is one of the most widely used security systems, and the most suitable construction site monitoring system on the market is handheld video communication equipment. Video monitoring is now the mainstream. From the earliest analog surveillance to the popular digital surveillance in previous years, and now the rise of online video surveillance, there has been a tremendous change. Today, as IP technology gradually unifies the world, it is necessary for us to have a new understanding of the development history of video surveillance systems. From a technical perspective, the development of video surveillance systems can be divided into the first generation of analog video surveillance systems (CCTV), the second generation of "PC+multimedia card" based digital video surveillance systems (DVR), and the third generation of fully IP network based video surveillance systems (IPVS)
