Channel Vision B-321 - Amplified Balun Kit for Audio, Video & PTZ Control

Channel Vision’s Amplified Balun Kit for Audio, Video ; PTZ Control, provides the necessary impedance transformation to transition from 75 ohm coax to twisted pair cabling. An amplifi ed balun kit is a smart way to deliver video, audio, and data from a Pan Tilt Zoom Security Camera when you only have a single CAT5 cable running to the camera location from great distances. The low cost simple functionality, and availability of CAT5 cable, makes the B-321 a convenient choice for both new construction and retro-fi t applications.
