Certainly in my area they seem to just wear dark plain hoodies and face masks and don't care much about cameras as at 4am no-one is likely monitoring any alerts that come up and once people see the footage in the morning there isn't anything distinctive to ID them.

I have seen some cases of just using spray paint or even some kind of oil or whatever else to mess up the lens (mainly for doorbells or otherwise where the camera is easy to reach and see) or if it's too far out of reach they just throw rocks or hit it with a long stick or similar until it's out of action.
