Video & Power thru balun , 4 cameras solution

4 cameras solution

The Lemar 4 CH CCTV Video Balun allows 4 base-band composite video signals and Power supply as well Data to be transmitted via unshielded twisted pair (UTP) cable for more versatile cabling.

The 4 CH CCTV Balun can be used with CCTV power & data thru balun or CCTV Power converter for wide applications, and allow you to eliminate more expensive coaxial cables, including coupling signals from remote video cameras to display systems, video capture, security and surveillance monitoring applications.
