16 Port Active UTP Video Hub Up To 3,000 Feet With Passive Baluns
The Nitek 16 port active video hubs VH 1656M 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 VH 1656M 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 power.
