The full form of CCTV is Closed Circuit Television. As the name suggests, CTTV operates on a closed circuit, unlike regular TVs that broadcast signals to the public. In this way, signals from the cameras are transmitted only to a specific set of monitors and recording devices thus, forming a private network. This restricted access makes CCTV an ideal choice for surveillance and constant monitoring. They are generally used in banks, offices, shops, casinos, corporate houses, airports, and many other places.
