What is a Complete CCTV System Made Up Of?

Many people assume that just CCTV is just cameras but there are other elements that make up a complete system. We take a look at what comprises a complete CCTV system.

 

Cameras

 

The most obvious part of any CCTV system, the cameras capture images and also provide an effective visual deterrent to potential burglars and intruders. There are a wide range of cameras all suitable for different circumstances including:

 

• IPTV cameras
• Dome cameras
• Bullet cameras
• Infra red cameras

 

Cables

 

The cables that run from the cameras to the DVR (digital video recorder) have two functions. Firstly they supply them with power. No power to the CCTV cameras, no images. Secondly, they transfer the live images back to the DVR.

 

DVR (Digital Video Recorder)

The very heart of the CCTV system, the DVR takes all of the camera inputs and puts them onto the viewing screen and also stores the images and footage for later viewing. Late models support remote access over the internet which means you can access your CCTV from anywhere in the world.
