My buddy suggested this as well. He said make sure to hide em good, or they'll probably steal em.
Game/Trail-cams can and are bolted to shit for precisely this reason.
Also use a ladder, chances are your buddies won't think to bring one and makes trying to rip the thing off with brute-force a hilariously precarious affair best observed from a second trail-camera. It doesn't need to be a tall one either, just a foot or two above eye level is often plenty.
I suggest game-cams since they are essentially motion-activated outdoors-rated night-vision capable surveillance-cameras... and are often better resolution than actual security-cameras (which are geared more for wide area coverage rather than being able to ID one wild animal from another of the same species).
The upside of these is that even if they cannot ID the person, they CAN tell the police which fingerprints came from the suspect and
immediately narrows down their investigation. Plus they sometimes can grab a license-plate number, which is helpful.
But yeah, if bolts aren't your thing,
metal banding straps screwed deep into the beam to the point that the head (which is a non-standard torx or square-drive-head) is hidden from view. Bonu points if the straps are further protected with a board nailed over it.
