Which of the following describes CCTV?

Closed Circuit Television (CCTV) refers to a system of video cameras used for surveillance and monitoring purposes. The term 'closed circuit' indicates that the video footage is transmitted to a specific set of monitors or recording devices rather than being broadcast publicly. This ensures a more secure and controlled environment for viewing the footage, which is essential in various safety and security applications, such as on ships, in public spaces, and in private properties.

CCTV plays a crucial role in enhancing fire safety, as it allows operators to monitor conditions in real-time, helping to identify potential fire hazards or active incidents rapidly. Additionally, recorded footage can be instrumental in post-incident analysis, aiding in investigations and improving future safety protocols.

In contrast, the other options do not accurately define CCTV. Central Control Tracking Visuals, Community Camera Televisions, and Concealed Closed TV do not reflect the standard terminology or function of closed circuit television, which emphasizes both security and surveillance aspects.
