Coaxial Cable Recommendations
Caution: Careful selection of proper cable is essential to obtain the best performance from this
equipment. Vicon assumes no responsibility for poor performance when cables other than those
recommended, or equivalent, are installed. In all cases, coaxial cable impedance should be 75 ohms.
Materials
Use only a pure copper center conductor. Do not use a copper-plated steel or aluminum center conductor,
as they will result in poor quality video. Solid-core bare copper conductor is the best type, where flexing and
bending will be minimal. If severe bending and flexing is required for installation, use a stranded center
conductor. Never exceed the manufacturer's minimum bend radius specification. Use cellular (foam)
polyethylene dielectric except where heavy moisture exists. For moisture conditions, use solid polyethylene
dielectric cable with a heavy exterior insulation. The shield must be copper braid providing 95% or better
coverage.
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
distance 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.
