A CCTV (closed-circuit television) system is a surveillance technology consisting of cameras, monitors, and recording devices used to monitor activities in a specific area. CCTV systems are commonly used for security and surveillance purposes in various settings such as homes, businesses, and public spaces. The cameras in a CCTV system capture video footage which is then transmitted to monitors for real-time viewing or recorded for future playback. CCTV systems can help deter crime, provide evidence in criminal investigations, and enhance overall safety and security in a given location.
