Network Cabling for Video Surveillance Guide

Author: Brian Rhodes, Published on Oct 30, 2015

In this 14 page guide, we teach the fundamentals of network cabling for video surveillance networks, how they should be installed, and the differences in testing them for production networks.

Specifically, we examine:

  • Cat 5e vs. Cat 6a vs Cat 7a Basics
  • Why More Than Cat 5e is Often Unnecessary for Video
  • STP vs. UTP Overview
  • When You Should Use STP
  • Solid vs. Stranded vs. CCA
  • Wiremapping
  • Cable Identification
  • Service Detection
  • PoE Detection
  • Cable Labeling
  • Using Cable Trays & Hooks
  • Importance of Cable Jackets
  • Why Drawing Maps Is Vital
  • Avoiding Excessive Service Loops
  • Installation Specifications
  • Crosstalk Defined
  • Propagation Delay
  • Cable Verifiers
  • Cable Qualifiers
  • Cable Certifiers
  • Choosing Between Verifiers, Qualifiers and Certifiers
