Closed-circuit television (CCTV) is a system of video cameras used for surveillance and security purposes. It is used to monitor and record the activities of people in a given area. CCTV systems typically consist of cameras, monitors, recording devices, and other related equipment. The cameras are usually connected to a recording device or IP network, and the video feed is then viewed by a security guard or other authorized personnel. CCTV can be used in a variety of settings, including homes, businesses, public places, and government buildings. It is also used to monitor traffic, prevent crime, and provide evidence in criminal investigations.
