8 & 16 Port UTP Video Hub

The VH839, VH839M, VH1639 and VH1639M Video Balun Hubs are

multi-channel video transmission devices that provide a low cost means of
sending quality live video over category 2, 3, 4 or 5 twisted pair cable. The
system works equally well over existing communication and computer network
spare pairs, or new cable installations.

The units can send video up to 1,000 feet when used with other

products in the VB37 or VB39 family. When used with model TR515 or TR560
active receivers, distances of 1,500 feet and 3,000 feet respectively can be
obtained. The units are designed to provide superior immunity from noise and
interference even when run near power lines. Additionally, the unit has built-in
surge suppression to protect video equipment from harmful power lines and
lightning related type surges.

It can be rack mounted using the supplied mounting ears or used as

a desktop unit without the mounting ears.
