What is CCTV and How Does it Work?

Closed-circuit television (CCTV) is a surveillance system that uses video cameras to transmit video footage to a monitor or set of monitors. The cameras are connected to a recording device, such as a digital video recorder (DVR), which stores the footage for later viewing.

CCTV systems are often used in both commercial and residential settings to increase security and monitor activity. They can be used to monitor entrances, exits, and other areas where security is a concern. Some CCTV systems even come with features like motion detection and night vision, making them suitable for 24/7 surveillance.

CCTV cameras can be mounted in a fixed position or attached to a pan-tilt-zoom (PTZ) mount that allows for remote control of the camera’s position. Footage from CCTV cameras can be viewed in real-time or saved for later viewing.
