Cable Types
The cable types listed below are the most common 75-ohm types used. They vary in size (diameter),
dielectric type and net DC resistance. The larger cable results in a lower DC resistance and better video
quality, with increased difficulty in handling and installation. Let the required picture quality and cable
distances provide a guide in choosing the best cable type. For cables other than the approved Vicon types
below, contact the manufacturers listed below. Note that “BC” refers to bare copper and “TC” refers to tinned
copper.

** For longer cable runs, use a Vicon Video Amplifier to obtain a suitable picture.
Video Amplification
If you are using a video signal amplifier between the camera and Kollector, verify good picture quality from
video source to destination. Remember that amplifying a noisy signal does not only amplify the signal but the
noise as well. A noisy video signal will affect the Kollector unit’s recording and performance, causing poor
video quality and high storage consumption.
