Tail Cable Repair Guide for Techage POE Camera

When repairing the tail cable of a Techage POE camera, many customers may wonder how to properly connect the severed wires. This guide provides step-by-step instructions to help you successfully repair the camera’s tail cable and addresses common questions.

Tools Needed:

• Wire cutters
• Wire strippers
• Electrical tape
• Heat shrink tubing (optional, for reinforcing the connections)
• Multimeter (optional, to test the wiring)

How to repair tail cable for PoE Cameras？

Step 1: Inspect the Tail Cable

First, disconnect the POE camera from the power source. Check the tail cable for any damage or broken wires. If any wires are damaged or cut, trim the damaged section and make sure you have enough cable length left to complete the repair.

Step 2: Strip the Cable Insulation

Use wire strippers to carefully remove the outer insulation from both the tail cable and the new network cable, revealing the eight internal wires. Be cautious to avoid cutting or damaging the internal wires.

Step 3: Wire Color and Sequence Matching

To correctly reconnect the severed tail cable to a new network cable, follow the color sequence as outlined below:

1. Tail cable white-blue connects to network cable white-orange (Sequence 1)
2. Tail cable blue connects to network cable orange (Sequence 2)
3. Tail cable white-green connects to network cable white-green (Sequence 3)
4. Tail cable green connects to network cable green (Sequence 6)

The remaining wires should be left disconnected:

• Sequences 4, 5, 7, and 8 are not used in this particular camera model and do not need to be connected.

Step 4: Reconnect the Wires

1.Match the wires from the tail cable to the new network cable according to the sequence described in Step 3. You can use one of the following methods to reconnect them:

• Twist method: Twist the copper wires of each matching pair together.
• Soldering method: If possible, use solder to make the connections stronger and more reliable.

2.Wrap each connected wire pair with electrical tape or use heat shrink tubing to ensure a secure, insulated connection, protecting it from moisture and external factors.

Step 5: Test the Connection

After reconnecting the wires, you can use a multimeter to check if the current flows correctly through the wires, or you can simply reconnect the camera to the POE switch to test if it’s receiving power and transmitting data properly.

Step 6: Waterproofing

Once the repair is complete, use waterproof tape or heat shrink tubing to reinforce the connection points. This is especially important if the camera is used outdoors, as it will protect the tail cable from moisture and prevent further damage.

Common Customer Questions

Many customers wonder why certain wires and sequences are not connected. Here’s the explanation:

• Purple and black wires: These wires power the camera’s indicator light. If the indicator is no longer working, it’s because these wires have been cut, so there’s no need to reconnect them. This won’t affect the camera’s core functionality, as the light is only an auxiliary feature.
• Sequences 4, 5, 7, and 8: These sequences are not used in Techage POE cameras by default, so they do not need to be connected.

However, if you are using a separate POE power supply, you may need to connect these wires:

• Sequences 4 and 5: Connect to the yellow wire.
• Sequences 7 and 8: Connect to the gray wire.

This configuration is for specific POE setups. For most standard POE switches, you only need to connect the primary wires and can leave sequences 4, 5, 7, and 8 disconnect

By following these steps, you can successfully repair the Techage POE camera’s tail cable and ensure it operates as expected. If you have any further questions during the repair, refer back to this guide for assistance.
