Description
The VH439 video balun hub is a multi-channel video transmission device that provides 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 VH439 can send video up to 1,000 feet when used with other products in the VB37 or VB39 family. When
used with a DVR the VH439 must be limited to 750 feet. When used with Model TR515 or TR560 active receivers,
distances of 1,500 feet and 3,000, respectively, can be obtained. The VH439 is designed to provide superior
immunity from noise and interference even when run near power lines. Additionally, the unit has built-in surge
arresting to protect video equipment from harmful power lines and lightning related type surges.
