CCTV (Closed-Circuit Television) surveillance is a system that uses video cameras to monitor and record activity in a specific area or location. CCTV surveillance is commonly used for security and surveillance purposes in public places, such as banks, schools, airports, and retail stores, as well as in private residences.

The system typically includes one or more cameras, a video recorder, and a monitoring system that allows security personnel or property owners to view live or recorded footage. CCTV surveillance can help deter crime, monitor suspicious activity, and provide evidence in the event of an incident or crime. It can also provide a sense of security and peace of mind for property owners, employees, and customers.
