Closed Circuit Television (CCTV) equipment is a type of electronic surveillance system that uses cameras to capture and transmit video footage to a central monitoring station or device. CCTV systems are commonly used for security, surveillance, and monitoring purposes in a variety of settings, including residential properties, commercial buildings, and public spaces.

CCTV cameras: These are the primary components of a CCTV system. CCTV cameras are electronic devices that capture and transmit video footage to a central monitoring station or device. They can be mounted on walls, ceilings, or poles, and are typically connected to a central control system via a wired or wireless connection. CCTV cameras come in a variety of shapes, sizes, and types, including dome cameras, bullet cameras, and PTZ (pan, tilt, zoom) cameras.

DVR (Digital Video Recorder): This is a device that is used to record and store video footage from CCTV cameras. DVRs are typically connected to CCTV cameras via a wired connection and are used to capture and store video footage for later review. DVRs can be standalone devices or can be integrated into a central control system. They can be used to record video footage continuously or can be set to record only when certain conditions are met (e.g., motion detection).

In summary, CCTV equipment consists of cameras and DVRs that are used to capture and transmit video footage for security, surveillance, and monitoring purposes. These systems can be used in a variety of settings and can be configured to meet the specific needs of the user.
