We are providing CLOSED-CIRCUIT TELEVISION(CCTV) service, CCTV camera is used as 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 openly transmitted, though CCTV services may be employed as point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit in 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. Video telephony is seldom called “CCTV” but the use of video in distance education, where it is an important tool, is often so called.
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for the places where 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.
