CCTV
This term is an abbreviation for Closed-Circuit Television. It refers specifically to a private monitoring system rather than a broadcast system, meaning the signal is not transmitted publicly. In common usage, it is often used metonymically to refer to the cameras themselves or the recorded footage produced by the system.
While the term is used globally, it is particularly prevalent in British English. In North American English, terms like surveillance cameras or security cameras are more frequently employed in casual conversation, though CCTV remains the standard technical term in security and legal contexts.
