32 Port Active UTP Video Hub 100 Feet To 6,000 Feet

The Nitek 32 port active video hub VH3256 with built-in surge suppression, ground loop isolation, gain and 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.

These active video 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 VH3256 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.


Available Configurations Include:

VH3256/110 Active Video Balun Receiver Hub - 32 Ports - Selectable 100 feet to 6,000 feet  - with 110 punchdown
