What does the acronym "CCTV" stand for in security?

CCTV stands for Closed-Circuit Television, which is a widely used technology in the field of security and surveillance. This system transfers video signals from cameras to a set of monitors or recording devices that are kept privately, rather than being broadcast publicly. Closed-circuit television is essential for observing and monitoring specific areas, which enhances security by deterring criminal activity and providing real-time viewing and recording capabilities.

The focus on "closed-circuit" indicates that the video feed is sent to a limited number of screens instead of broadcasting it over the airwaves, which offers a higher level of privacy and security. This distinguishes CCTV from public broadcasting systems, making it a preferred choice for businesses, public places, and residential properties to maintain safety and ensure accountability.

Other options, while they might sound plausible, do not accurately reflect known industry terminology and practices associated with security and surveillance systems. They don’t capture the nature or function of CCTV as effectively as the correct answer does.
