Digital Audio Balun The Digital Audio Balun allows one Digital Audio signal to be transmitted via one Cat.5/6 twisted pair cable for more cost-efficient cabling.  The CCTV Video Balun allows baseband composite signal to be transmitted via a single unshielded twisted pair (UTP) cable for more versatile cabling. The CCTV Balun is used in pairs to allow you to eliminate more expensive coaxial cable, including coupling signals from remote video cameras to display systems, video retrieve, security and surveillance monitoring applications. The use of existing twisted pair infrastructure such as telephone cable and Cat.5 computer networking cables are also available. All our baluns are 100% test for reliability and durability to guarantee your signal integrity. ‧Specification 1.
