Nitek CX254 - Manual (Page 3)

UTPLinks INTERMEDIATE POWER DISTRIBUTION
In a system, equipment is often spread out over a large facility and the communications backbone of that facility is
used for the routing of the video and data signals. Power is inserted at the IDF (Telco closet) located closer to the camera
end.
Starting at the camera end, there are several UTPLinks transmitter units available, only one is shown here. These
units allow 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 run back to a patch panel in the IDF, up to 100 me-
ters away for TIA/EIA standards and 750 feet for standard analog fixed cameras. Distances for PTZ cameras are deter-
mined by the power requirements of the camera. From the patch panel each camera is sent to the CX254 unit. The CX254
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 the
CX254.
Video from and data to the cameras is routed through the RJ45 jacks on the rear of the CX254 unit. Signals are
routed over a facilities backbone communication cable to the MDF (main Telcom center). From the MDF they can be re-
routed to the security room.
In the security room these signals are taken back off of the backbone and put into NITEK video receiver units.
Once they are decoded in the receiver units these video signals are fed out BNC jacks for connection into standard CCTV
equipment. In our current example, a DVR is viewed on a monitor. It could have been a matrix, multiplexer or any other
equipment needed for your application.
