What is the best position to install the rear camera of a dash cam?

The rear camera of a dash cam can be installed either on the rear windshield inside the car or on the license plate light cover. The specific steps for installing it on the rear windshield are as follows: 1. Route the power cable along the gap between the rear seat and the roof, tucking it neatly along the edge; 2. Mount the camera at the center top of the rear windshield. For installation on the license plate light cover: Route the wiring through the trunk, along the edge of the trunk, and then mount it on the license plate light cover, adjusting the angle properly. After installing the dash cam, it can record video and audio of the entire driving process, providing evidence in case of traffic accidents. While driving, it continuously records video, capturing details such as time, speed, and location in the footage.
I think it depends on your car model and personal usage habits. For my own car, mounting it right in the center at the top edge of the rear windshield with 3M adhesive works best. The advantage is the unobstructed view that captures the entire rear scene, and the wipers can help clean the glass during rain without affecting the recording. If you frequently drive long distances hauling cargo, installing a waterproof camera above the license plate holder is also reliable—though wiring is a bit more troublesome, the footage gives a more accurate sense of the actual distance. But never install it on the left or right C-pillar positions—those angles are too skewed to capture vehicles directly behind, as I learned the hard way when I was rear-ended and almost suffered serious consequences. Mounting inside the car is much safer than outside—last time I saw a friend’s camera above the license plate get shattered by flying gravel.
