The NetMedia UTPEYE is a general purpose surveillance camera that utilizes a built-in NetMedia UTP Video Encoder and external UTP Video Decoder to exchange power and video across Unshielded Twisted Pair (UTP) cable, such as CAT5. There is no need to run multiple cables to the camera location! It mounts in round 4 inch electrical fixtures or 2.7 inch diameter holes and is viewed with a security monitor or television. To view the camera on a single standard television, use the TV's composite RCA Video Input jack.
