Closed-circuit television (CCTV) system consists of video cameras which transmit signals to a specific, limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point-to-point wireless links. CCTV is often used for surveillance in areas which need security such as banks, airports or military installations.
