The VH456 is a four port active video mini-hub with gain and loss control, built-in surge suppression, ground loop isolation 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.
These active video mini-hubs are multi-channel video receiver devices that provide a low cost means of receiving quality live video over category UTP cabling. The systems can also adapt to existing communication and computer network spare pairs or new cable installations. The VH456 can be used on video runs up to 3,000 feet (900 meters) when used with passive transmitters or distances of up to 6,000 feet (1,800 meters) with the Nitek TT560 active transmitter. These hubs provide superior immunity from noise and interference, even when run in common raceways with AC.
