I've rig'd up an alarm in our job boxes.. those 12V car alarms.. takes alittle room in the box, but i've found that a cars battery will last most of the nite .. someone opens the box it just gives them a nice ear blast of noise.. and if its not too rural.. it generally gets someones attention.. I've also gone as far as finding a spot where i put a camcorder (color) over our job box area.. police like that one.. saved my comp a few thousand..
