Hikvision Video Balun DS-1H18
The set of DS-1H18 baluns allows for the transmission of the video signal from one source via a twisted pair cable. Thanks to the small size of the baluns and combination with BNC plugs there are no problems with direct connections to BNC sockets of DVRs, even when they are densely packed.
The balun matches the impedance of unbalanced 75-ohm output/input with 100-ohm impedance of the balanced line, and vice versa. In the case of a UTP/FTP cat. 5 cable, the transmission line can reach 150 meters (signals from HD-TVI, HDCVI, AHD cameras) or 400 meters (signals from CVBS cameras).
The installer should pay attention to connecting the appropriate leads to the correct terminals: (+) to (+) and (-) to (-). The improper connection will cause interference.
Please be aware of running power over CAT5 as voltage drop will occur.
CCTV video baluns, also known as UTP baluns, allow traditional coax cable to be replaced by category 5 and other forms of twisted pair wire in CCTV video camera & surveillance installations. Video baluns allow installers to use more cost-effective structured cabling techniques to wire security cameras. By using video baluns, UTP wire such as cat-5 can be run over long distances easier than coax cable and for less money. Active balun transceivers enable UTP wires for cameras to be run distances up to 5,000 feet. If you are new to the idea of using baluns for video, check out our video balun installation videos.
This page contains baluns for analogue CCTV cameras and HD security cameras (AHD, HD-TVI, HD-CVI).
Please be aware while video signal can be carried over a longer distance, power is limited to 50 meters for cameras amperage up to 250mA and 30 meters at 600 mA.
Do not pair up the cable carrying the video signal but the other pairs will need to be paired for power.
