What Is CCTV?

CCTV ( Closed-Circuit Television ) is also known as video surveillance. The term “Closed-circuit” refers to the fact that the video footage is shared to a limited number of monitors from strategically placed cameras inside and/or outside a building. A CCTV system, therefore, refers to all components and aspects that make the system complete, such as the camera, monitors, cabling (network infrastructure if using IP), video storage and video management system.

What does CCTV stand for?

CCTV stands for Closed-Circuit Television.

Who invented CCTV?

CCTV history is not 100% clear. Walter Bruch is credited with inventing CCTV in 1942 to observe the launch of rockets in World War 2. However, an earlier mechanical CCTV system was developed in June 1927, by Russian physicist Léon Theremin.

Where is CCTV most commonly used?

Although CCTV has a wide range of uses it is more often used to detect and deter crime and provide evidence of this. CCTV is also used in areas such as traffic management and retail intelligence.
