Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a central console for scrutiny via a set of monitors.
CCTV is often used for in areas that need security guards to continuously monitor the movement of people or for potential intrusion. CCTV is commonly used in banks, supermarkets, office blocks, airports, embassies, go downs, military installations and casinos.
In industrial plants, CCTV equipment may be used to observe production processes from a central control room if the production environment is not suitable for humans.
