Is there any easy way to detect the source of that 905nm radiation like e.g. making IR visible with a camera?
If you have an IR Camera you should be able to find it but there is definitely something there. I do see a camera on the right before you enter the tunnel and also some cameras inside the tunnel but these devices are not used in the US so I cant be sure. Even if not aiming at you there will be reflections that your front sensors will pick up.
