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.
