CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV is designed to help prevent and detect crime. It can reassure the public about community safety. It is located in public places to: provide evidence to relevant enforcement agencies.Cameras record images twenty four hours every day. CCTV operators watch lives images at strategic times in a local monitoring suite. If they notice criminal activity on camera, they can direct police response to the incident.These images (and often audio too) are transmitted to the recorder or tape, either wirelessly or by cable. Recorders may use analytical software and other smart technologies to scan the data and send automated alerts to either humans, or other systems and devices. This Video Management Software (VMS) records, stores and analyzes video feeds. The software is often self-learning, using machine learning (ML) algorithms that utilize functionality like motion detection, face recognition, people counting, etc.
