Closed-circuit TV, or simply CCTV, is the application of digital cameras to transmit an image to an exterior location, via a limited number of monitors, for security purposes. The term closed-circuit TV originated from the need for multiple monitors for the security needs of the military, police, and fire departments, which required more space for monitoring the cameras and controlling the transmission.
Closed-circuit video is the same concept of security cameras, but with fewer cameras. In closed-circuit video, an image from a digital camera, normally a camcorder that records in high definition, is transmitted to an external source (TV, computer monitor, DVD player or similar device). This type of security camera can be a stationary system or can be moved. The type of closed-circuit TV used for surveillance purposes will depend upon the needs and requirements of the security officials.
Video surveillance cameras can be used by the police and military as well. These types of closed-circuit video systems are commonly used in the detection of criminal activities, for the protection of employees, in the detection of suspicious behavior, or for other reasons. There are various uses for closed-circuit TV in industries such as the manufacturing industry, where the detection of fires, explosions, or the reduction of employee injury and property damage are important.

Another form of closed-circ video is used in the retail industry. Retail surveillance cameras can be used in retail stores to monitor security in storerooms, to provide assistance in customer service, and to provide for security during sales.
