Network Cable Testing Guide

Author: Ethan Ace, Published on Jan 22, 2015

Proper cable installation is key to trouble-free surveillance systems.

However, testing is often an afterthought, with problems only discovered when cameras have problems, resulting in increased troubleshooting, or even worse, reinstallation. Simple, inexpensive testers are available, which can easily prevent these issues without adding substantial install time.

In this guide, we examine:

  • Wiremapping
  • Cable Identification
  • Service Detection
  • PoE Detection
  • Crosstalk
  • Propagation Delay
  • Cable Verifiers
  • Cable Qualifiers
  • Cable Certifiers
  • Choosing Between Verifiers, Qualifiers and Certifiers
