What is "closed-circuit television"?
Closed-circuit television (CCTV) is a system of video cameras used to monitor and record specific areas for security and surveillance purposes. Unlike broadcast television, CCTV transmits video signals to a limited set of monitors, usually within the same building or network, allowing only authorized viewers to see the footage. CCTV is commonly used in places like businesses, public spaces, and homes to deter crime, monitor activities, and enhance safety by providing real-time observation and recording of events.
