Why install a CCTV system?
For many people the reason is to use the pictures in evidence or to see what is going on when they are not there. The most effective way to achieve this is to use a multiplexer connected to a video recorder.

A typical CCTV design features a Halon Bank Multiplexer, which when used with the associated video cassette recorder, will provide an historical record of all the cameras connected to the system. At the same time displaying pictures as full screen images. During the day to day running of the CCTV system the Halon Bank
Multiplexer will store full screen pictures from all of the cameras onto the video recorder.

If you only want to see pictures of what happens while you are away from your premises the multiplexer for you is the Halon Bank Simplex Multiplex. This records images from all the cameras and means that on play back each camera can be viewed independently, for maximum detail or in multiscreen format where all of the cameras are displayed at the same time.

After an incident the operator replays the video recorder and watches the Multiscreen display to find the best picture from those available.

Then a particular camera is selected on the Multiplexer. The Multiplexer then displays that picture as a full screen view, for the best possible detail.
