RJ45 Plug Wiring

How to wire RJ45 plug for an IP CCTV Camera 

RJ45 plug wiring made easy with Videplus. When wiring up an IP camera, or any other IP device for that matter, you must use network cable such as CAT 5e or CAT6 containing 4 pairs of wires. Each pair consists of a solid coloured wire and a strip of the same colour on a white background. The plugs used for connecting network cables are called RJ45 plugs and RJ stands for “Registered Jack”.

There are two standard colour codes for RJ45 Plug Wiring: T-568A and T-568B. Although there are 4 pairs of wires, 10BaseT/100BaseT Ethernet uses only 2 pairs: Orange and Green. The other two colours (blue and brown) may be used for PoE. The two wiring standards are used to create a cross-over cable (T-568A on one end, and T-568B on the other end), or a straight-through cable (T-568B or T-568A on both ends).

You would normally use a standard T-568B wiring for both ends of your cable when connecting equipment. Such as IP Cameras, Printers and Computers etc. to a Router or to an ethernet switch or hub. (you could use both T-568A instead but this is less common and not recommended).

Step-by-Step Guide to wire RJ45 Plug

Materials Needed:

  • Crimping tool
  • RJ45 connectors
  • Cat5e, Cat6, or Cat6a cable
  • Wire stripper/cutter
  1. Prepare the Cable. Strip about 1 inch of the outer jacket from the cable using a wire stripper
  2. Untwist the four pairs and arrange them in the T-568B colour order, as described below:
    • Pin 1: White / Orange
    • Pin2: Orange
    • Pin 3: White / Green
    • Pin 4: Blue
    • Pin 5: White / Blue
    • Pin 6: Green
    • Pin 7: White / Brown
    • Pin 8: Brown
  3. Trim the wires to the same length. Ensure they are flat and even.
  4. Insert the wires into the RJ45 Connector. The flat side of the plug should face upward with the clip facing down.
  5. Crimp the plug using a crimping tool to secure the RJ45 to the cable. Make sure the contacts pierce the wires and the cable jacket is secure.
  6. Test the connection to ensure the wiring is correct and the cable is functional.
