GEM Electronics CCTV Balun Power-thru Type Video and Power (Lead Free)
The CCTV Power-thru Balun provides the transmission of video signals and remote power via a single UTP (unshielded twisted pair) cable for more versatile cabling. The CCTV Power-thru Balun is used in pairs that allow you to eliminate more expensive coaxial cable, which include coupling signals from remote video cameras to display systems, video capture, security and surveillance monitoring applications.
The use of existing twisted pair infrastructure (such as telephone cable and cat. 5 computer networking cables) is also available. All of our Baluns are tested 100% for reliability and durability to guarantee your signal integrity.
