This CCTV Diagram depicts a video surveillance system. The CCTV diagram shows a strategy for placing video cameras. CCTV diagrams should include a plan for strategically placing video cameras that capture and transmit video to a private network of monitors for real-time viewing. CCTV is widely used for surveillance and security. Closed-circuit television (CCTV) is video surveillance that employs cameras and monitors. Unlike broadcast television, this system only receives local signals. Although it is a feature of almost every video camera, CCTV is primarily a system for visual control of specific areas such as banks, airports, supermarkets, and other places for security purposes.
