What is the primary purpose of closed circuit television (CCTV)?

The primary purpose of closed circuit television (CCTV) is to monitor and record activities in a specific area for security and surveillance. CCTV systems are widely used in various settings, such as commercial buildings, public spaces, and residential areas, to enhance security measures and deter criminal activity. They allow for real-time monitoring and can record footage that can be reviewed later if needed. This capability to provide surveillance helps in protecting property, ensuring safety, and gathering evidence in the event of criminal activity or incidents.

While providing entertainment in public areas, improving traffic flow in cities, and facilitating communication between remote locations are important functions in other contexts, they do not align with the primary security-focused function of CCTV. The effectiveness of CCTV systems in reducing crime and improving safety makes their primary purpose distinctly centered on surveillance rather than the other listed options.
