Walking past the Sandcastle in Clearwater I've always noticed what appear to be motion sensors in some places. Does anyone know anything about these? I'll try and get a picture if I can.

Yes very observant of you my friend.....on all prop......across from checkers then across from the thrift store at the motel...down by the waterfront rest. and the living quarters at hacienda gard. too.......funny to just pass them over and over with your hand as you pass by and watch the guys come out and see whats up over and over hahaha or bend a branch to hang in the way of the beam....that really confuses them for some reason?
