Chapter 10 – Network Cable
Recommendations
Caution: Careful selection of proper cable is essential to obtain the best performance. Vicon assumes no responsibility for poor
performance when cables other than the recommended types, or equivalent, are used.
Materials
Use pure copper stranded conductors to obtain a low DC resistance. The preferred insulation and cable jacket is Polyvinyl
chloride (PVC). It has better electrical characteristics than Polyethylene and resists flames, sunlight and most solvents,
but is more vulnerable to moisture.
Cable Types
The most commonly used cable types are CAT5, CAT5e and CAT6. These category cables are best suited for Ethernet
network applications.
Choose a Belden cable type by referring to the characteristics listed below. The Table below should be used as a
guideline when cables other than Belden are used. Materials and construction must follow the guidelines above.

*For any cable in the system exceeding 300 ft (75 m), it is recommended to use Cat5e or higher to maintain good signal integrity.
