Introduction
This manual is designed to cover the VH456 receiver
hub. The VH456 receiver can be hooked up to several
different Nitek UTP passive transmitter units depending
on the transmission distance you need to go. The two
main types are, the passive transmitter and the active
transmitter. The passive transmitter requires no power
and can provide video up to 3,000 feet. Active
transmitters can provide video up to 6,000 feet. For
longer distances consult Nitek for other available
systems.
Note: This installation should be made by a
qualified service person and conform with local
codes.

VH456 Common Hookup Diagram
Determining Cable Length
Check the twisted pair for continuity. Do this by
shorting the pair of wires at one end and use an
ohm meter to check the resistance at the other
end. Use the chart to determine the length of
your wires for a measured resistance. Also, use
a multimeter to test the line and make sure there
is no voltage on it. Testing each line and
recording the length for each camera run can
greatly reduce installation time. For distances
greater than 3,000 feet an amplified transmit
source may be needed.
