UTPLinks HEAD-END DISTRIBUTION
In a head-end system all equipment is located together. There is no backbone copper and all of the horizontal
runs are limited to 100 meters (TIA/EIA standards), so passive receivers can be used.
Starting at the camera end, there are several UTPLinks transmitter units available, only one is shown here. This
unit allows the video, power and data to be separated out and fed into standard CCTV cameras.
From the transmitter there is a standard 4 pair Category cable running back to a patch panel up to 100 meters
away (TIA/EIA standards). Using 24awg patch cables, connections for each camera are sent to the Crossover unit. The
Crossover unit provides a central point for the combining of the power, data and video signals. Each camera port is fused
and lights on each of the front panel RJ45 jacks show the status of both power and data.
Power for the system is provided by a Power Supply unit mounted under the Crossover unit. It connects to the
Crossover unit via snap in jumper cables that can be installed in seconds.
Data for the CX452 is routed through the 2 pin jack on the rear of the CX452 unit. In this system CHM22 cards
feed video out the front BNC jacks for connection into standard CCTV equipment. In this example, a DVR is viewed on a
monitor. It could have been a matrix, multiplexer or any other equipment needed for your application.
