Hang em high!!!!! We built a cage with Razor wire on the roof of one building to store the equipment. It has a door so we can get in without injury. The fire escape/maintenence ladder is also locked, and you practically need a fire truck with hook and ladders to get up there. You can also get some molding/panduit to wrap the building which requires a special tool to open. We also placed CCTV camera's for the building owner, that are tamper resistant and sit way up under the eve, but can not be reached without big ladders. The funny thing is, the building owner paid for all of this, because he was sick of seeing black wire and splitters strung up all over. That'll teach em!!!!
