  • Why More Than Cat 5e is Often Unnecessary for Video
  • STP vs. UTP Overview
  • When You Should Use STP
  • 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
