What are the components of a CCTV surveillance system?

A typical CCTV surveillance system consists of the following components: Cameras: These are the devices that capture video footage of the monitored area. They can be fixed or PTZ (pan-tilt-zoom) cameras for flexible monitoring. Video Management System (VMS): This is the software or hardware used to manage and control the CCTV system, including camera feeds, recording, and playback. Digital Video Recorder (DVR) or Network Video Recorder (NVR): These devices record and store the video footage captured by the cameras. Monitor :   A display unit that allows live viewing of the camera feeds or recorded footage. Cables and connections: These are necessary for transmitting video signals from the cameras to the recording devices and monitor. Power supply: Cameras and recording devices require a power source to operate.
