Anti-Theft Measures?

[BOZO]

When I worked on the road servicing rolling stock at Home Depot stores, I kept a driveway monitor in the trailer and kept the receiver beside the bed in my motel room. Any time you even opened the door of the trailer the receiver would let you know. These things are fairly cheap (25.00 range), and battery powered so they are very portable and easy to set up. The unit is basically a motion sensor. Another thing is, it does not see through glass, so setting one in the floorboard of your truck will not pick up someone just wqlking by your truck. The reason I know this is because I keep this monitor in my glass cased gun cabinet at home. When the door is closed, you can stand in front of the door and make all the movement you want, but open the door and it lets you know real fast.
