Most people don't know that their truck has a camera. The camera is located on the dash and is used to record footage of the road ahead. If you want to block your truck camera, there are a few things you can do.
The first thing you can do is put a piece of tape over the lens. This will prevent the camera from recording anything. You can also disconnect the power supply to the camera. This will disable the camera completely.
If you're worried about someone accessing your truck's camera, you can always remove it entirely. However, this should only be done by a qualified mechanic.
