CCTV (Closed Circuit Television) systems consist of cameras, monitors, and recording devices that work together to capture and display video footage of a specific area in real-time. The basic functionality of a CCTV system involves the following components:

• 1. Cameras: CCTV cameras are the primary component of the system. These cameras capture video footage of the monitored area and transmit the footage to a recording device or monitor. There are various types of CCTV cameras, such as dome cameras, bullet cameras, and PTZ (Pan-Tilt-Zoom) cameras, each with specific features suited for different surveillance needs.

• 2. Cables: CCTV cameras are connected to the monitoring and recording devices through cables, which transmit the video and power signals. The cables are typically run through walls, ceilings, or conduits to maintain a neat and secure installation.

• 3. Recording Device: The video footage captured by the CCTV cameras is stored on a recording device, such as a DVR (Digital Video Recorder) or NVR (Network Video Recorder). These devices have multiple channels to connect and record footage from multiple cameras simultaneously. The recorded footage can be accessed and reviewed later for security purposes.

• 4. Monitors: CCTV systems include monitors that display the live feed from the cameras in real-time. The monitors are typically placed in a control room or security station where operators can monitor the footage and respond to any security incidents as they occur.

• 5. Control Room: In larger CCTV systems, there may be a dedicated control room where security personnel monitor the live video feed from multiple cameras. Operators in the control room can pan, tilt, zoom, and adjust the cameras remotely to focus on specific areas of interest.

Overall, the CCTV system works by capturing video footage using cameras, transmitting the footage to a recording device for storage, and displaying the live feed on monitors for real-time monitoring. This allows for the continuous surveillance and protection of the monitored area against security threats. 4.

There are several advantages of using a CCTV system for surveillance:

• 1. Deterrence: The presence of CCTV cameras acts as a deterrent to potential criminals, as they are less likely to commit a crime when they know they are being monitored.
