Some images from my recent fog light camera install. These are both Logitech C930es, installed horizontally and held in by screws on either side. The USB cable is routed out the side below the air vent. Soon to be used for Automatic License Plate Recognition (ALPR) when the vehicle is running.
It appears stable, and relatively watertight.
Since they’re installed so low they’re not too noticeable, especially in daylight.
