描述: CCTV refers to a surveillance system that uses video cameras to transmit a signal to a specific, limited set of monitors. Unlike broadcast television, CCTV signals are not publicly distributed but are used for surveillance purposes, often to monitor the security of homes, businesses, public spaces, or other areas. CCTV systems provide real-time video footage and can also be used to record images for later review.
