IPCS Word of the Day: CCTV

CCTV = Closed Circuit Television. The use of video cameras to 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 that need monitoring such as banks, casinos, airports, military installations and convenience stores. In industrial plants, CCTV equipment may be used to observe parts of a process that are remote from a control room, or where the environment is not comfortable for humans. CCTV systems may operate continuously or only as required to monitor a particular event.
