uh they just can't..
What I mean by that is, they only open them when they see you walk in them
Make it like hiding under tables so they check them when they hear a noise

I think is should only be if they see you go into that specific closet so it doesn't get too op. Like if they know that you hid in there before, it would make sense for them to see if you did it again.
