In many security applications, video signal is carried over 75 ohm coaxial cabling and there is a need to convert to balanced transmission using lower cost 100 ohm twisted?pair cables.These Quad Baluns enable 4 video signals to be interfaced using coaxial on one side?to twisted pair cabling on the other using modular RJ45 connectors to achieve quick and reliable connections.Used in conjunction with E10172P or E1072PS will enable a neat professional?installation for up to 16 video paths.
