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 below to determine the length of your wires for a measured
resistance. Also, use the 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.
