What does CCTV Stand for – Full form of CCTV?

Definition and Meaning

The acronym CCTV stands for close-circuit television and also called video surveillance, it is the use of video cameras to transmit images to a particular place rather than broadcasting it over the airwaves. Although CCTV may use point-to-point (P2P) or mesh wireless links, the purpose is to send its signals to a particular single place. CCTV is most often used for video surveillance of properties such as banks, airports, military installations, convenience stores, and the like. There is also CCTV used in distance education where the viewer may be in a pre-determined location.

The first CCTV was created in 1942 by Tashira Arnold, Walter Brunch, and Wayne Cox to observe the launch of their V2 rockets from a safe location. By 1949, CCTV spread to the US where the first commercial system was started by Vericon. Since then, CCTV has spread around the world and is considered a primary part of surveillance technology.

CCTV systems are mostly used in industrial plants and other commercial locations to keep an eye on employees, visitors, and intruders. A series of video cameras are placed around the facility and are tied to a central location where security personnel can watch on monitor screens or record the information that is being sent. Today, many CCTV systems use digital video recorders which may keep the visual information that was sent for years. In addition, such systems are also used with motion detectors, IP cameras, and offer email alerts in case something is detected. Recently, the use of body cameras that utilize very small cameras represents the latest advancement in CCTV technology.
