CAT5e Wiring Guide

CAT5e Wiring Guide for Security Camera Systems

The most popular method for wiring security camera systems is to use CAT5e cable, video baluns and DC Plugs and Sockets as required. This is a simple step-by-step guide on how to send both video and power along a single length of CAT5e cable.

What You’ll Need

Tools Required

  • Wire cutters
  • Small screwdriver
  • Knife (optional)
  • Wire stripper tool (optional)

CAT5e Wiring Guide - What's Needed


  1. Pick a wiring convention and stick to it. Within each length of CAT5e cable are 8 individual wires. These are arranged as pairs. Each pair has a different color. Each pair has one solid color and one striped white + color wire. The convention we recommend here is use the orange pair for video. Use the solid color wires for positive and the striped wires for negative. It doesn’t matter what wiring convention you use – by sticking to it, installation is much easier!
  2. Using the wire cutters (or wire stripping tool if you have one) strip a length of the outer jacket off the cable.

  3. Peel back the weatherproof tape and cut off to keep it out of the way.

  4. Separate out the 4 pairs of wires and then separate out the individual wires.
  5. Strip the individual wires (again using either the wire cutters or the wire stripping tool if you have one)
  6. Now that you have prepared the wires you can start to fit the connectors. Start by fitting one of the video baluns using the push connections. Push the button in as you insert each wire into the hole. Then wire up the DC Plug or Socket with the remaining wires. To do this, unscrew each terminal, insert the wires (twist together to help them stay in place) then tighten each terminal.

Cable run Limits

Don’t forget to stay within the cable run limits – for this method of wiring, the limit is 200ft.

Ensure the CAT5e cable used is pure copper. Do not use CCA cable. All CAT5e cable we sell here at Orange Security is pure copper. Don’t take the chance!
