Hello. I have a M0024-2 camera, and am considering mounting the camera to my hardware by bonding the metallic square surface opposite the lens to my hardware. However, there are 4 small holes present on this face which I don't see in the smaller M0014 camera I also have. What is the purpose of these holes? I want to make sure I wouldn't be doing something detrimental by covering that face in epoxy (e.g. if they are for air venting or something like that).
