What does CCTV stand for? CCTV means Closed Circuit Television, which is a visual surveillance technology designed for monitoring a variety of environments and activities. CCTV systems are used in applications such as monitoring public areas for violent actions, vandalism, theft, and unlawful entry, both indoors and out. CCTV recordings are used to obtain and provide evidence for criminal and other investigations, they are sometimes disclosed to the media in the hopes of gaining information about images of a suspect or suspects caught in or near a crime scene.
Another term of CCTV refers to the fact that the system is self-contained, the signals only being accessible by equipment within the system. This is in contrast to ‘broadcast television’, where the signals may be accessed by anyone with the correct receiving equipment.
The term Closed Circuit Television can be misleading, as the word television actually means to see at a distance, which implies broadcast. If public broadcast is not the intent, CCTV is the correct terminology, as it is not a system for broadcast to the public in general. Unlike television that is used for public entertainment, a CCTV system is closed and all its elements are directly connected either by hardwired methods or wireless technologies.
