Installation 
 
UTP Video Receiver Hubs are designed to receive standard UTP 
video and output standard coax video. 
 
Step 1)

 

 

Check the twisted pair for distance and 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. The chart below will give you the length 
of your wires for a measured loop resistance. Also, use a multimeter to 
test the line to make sure there is no voltage on it. Testing each line 
and recording the length of each camera run can greatly reduce 
installation time. For distances greater than 3,000 feet (900 meters), 
longer range units may be needed. 

 

Step 2) 

 

Connect the twisted pair from each transmitter to the input 

terminals noting the polarity of the connection. If the wires are reversed 
the video will be unviewable on the monitor. Reversing the wires will not 
damage the unit. 
 
 

Step 3) 

 

The receiver hubs are powered from a 12-24 VAC/VDC power 

source. In the case of several units a larger central supply may be 
used.
