Which components are fundamental to establishing a CCTV system?

The fundamental components necessary for establishing a CCTV system include a video recorder, a camera, and a monitor.

The camera is essential as it captures the video footage that is essential for surveillance. This footage is then sent to a video recorder, which is responsible for storing the images and video footage for later review. Lastly, a monitor is crucial as it allows users to view live feeds or playback recordings from the video recorder, enabling effective surveillance and monitoring of the area being covered.

Each of these components plays a critical role in the functionality of a CCTV system, providing a complete solution for video surveillance. Without one of these elements, the system would be incomplete and unable to serve its primary purpose.
