CCTV Surveillance: The use of video cameras (Closed-Circuit Television) to transmit a signal to a specific, limited set of monitors for security and monitoring purposes. It’s commonly employed in public areas, businesses, and private properties to deter crime, monitor traffic, ensure public safety, and gather evidence for legal purposes. Advanced systems may include features like motion detection, night vision, and remote access. The widespread use of CCTV has implications for privacy and civil liberties, which are addressed by various regulations and laws.
