Nitek VH851M Video Balun Transceiver HUB (RJ45 Jacks) -8 Ports- Selectable 100 to 1500 Feet

8 or 16 port active video hubs with dual outputs, built-in surge suppression, ground loop isolation, gain/loss control, and video detection. Systems operate with other Nitek UTP video equipment including, video transceiver hubs, standard video balun transceivers, active transmitters, or any twisted pair equipped camera. Multi-channel video receiver hubs provide excellent video quality through two video outputs per channel. Twisted pair installations are made with a choice of the standard screw terminal connections, or the modular jack connections featured on the ‘M’ series. The VH851 can receive video up to 1,500 feet (457 meters) when used with passive transmitters. These hubs provide superior immunity from noise and interference, even when run in common raceways with AC power.
