Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may 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 from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced as a new form of surveillance.

Closed Circuit Television System (CCTV) provides on-line display of video images on a monitor . Color or black & white cameras with suitable lenses are used to scan specific areas to be Protected or monitored in any premises. Video signals from a camera can be transmitted to a Monitor over cables or in a wireless mode. CCTV systems can be designed to scan an area using a single or multiple cameras. In the latter case images from various cameras can be individually switched on to single monitor. Alternatively multiple camera images can be multiplexed and can be viewed in 4, 8, or 16 frame formats on the same monitor screen
