(As we all know, building monitoring has always been a major monitoring topic in the security office. Since the commercialization of security products, it has been widely used in building monitoring and community security protection. However, the traditional video surveillance system is limited by the development of technology. It can only perform local on-site supervision, simple alarm information transmission, and cannot transmit video signals over long distances. It is difficult to understand the detailed conditions of the front end and confirm the office.)
