These Baluns enable you to send your security camera or other video over an existing copper structured cabling system, CAT5 and other UTP. This set also has the added feature of DC power pass through. This enables you to input a DC power source and receive it at the other end.
Two baluns are included - one for each end. The unit designed to be at the remote end has the video input on a short lead so it can be installed away from the actual security camera.
