Dash cameras have become a common sight on our highways as they offer additional protection in the event of an accident or incident. With the rise of 2 channel dash cams, drivers now have the ability to capture footage of both the front and rear of their vehicle simultaneously. However, there are times when just one of the cameras on the 2 channel dash cam may not be working properly. In this article, we will provide you with some troubleshooting tips to help you troubleshoot the issue when just one of your cameras work on your 2 channel dash cam.

Troubleshooting Tips for When One Camera Works in a 2 Channel Dash Cam

Here are some common troubleshooting tips for when you are experiencing difficulty with the rear camera of your 2 channel dash cam:

Check the Cable and Ports between the Front and Rear Cameras

Most 2 channel dash cams come with two separate cameras. If one of the cameras isn’t working, the first thing you should check is the cable that is connecting the two cameras. Make sure that the cable is properly connected and that all ports are free of debris. Ensure the wire is not damaged or cut anywhere along its length. If you find that there is indeed damage, you will likely need to replace the cable.

Check for Issues with the Cable Running Through the Vehicle

Sometimes, the issue might not be with the cable or ports, but rather with the route taken through the car. Dahs cameras usually have the rear camera installed through the rear window of the vehicle. Make sure there are no sharp bends or kinks in the cable and that it isn’t getting caught or compressed in your trunk or hatch. Depending on the cable length provided, you might need to route around other areas inside the vehicle too.

Check if a Coaxial Cable Works

If the cable and ports are not the problem, then try swapping the rear camera cable with a standard coaxial cable. This can help determine if it’s the camera or the cable that’s causing the issue, and also identify the loss of signal in between the two cables. Using a standard coaxial cable might not provide as clear a picture as the camera’s dedicated cable, but it can be helpful in troubleshooting.

Check the Camera Settings and Update Firmware

Sometimes the issue might be software-related, you can go into your dash cam’s settings, verify if the rear camera is indeed enabled and check for any configurations that might be off. Also, check if there is the latest firmware is installed. Regular firmware updates tend to be provided by the dash camera manufacturer for the best performance, so it is useful to follow their prompts.
