Car Alarms: truck alarm, tool boxes, motion sensor

Question
We need something for the bed of my husbands work truck. He has an alarm on the tool boxes but someone got into the bed of the truck and stole some stuff. What would you recommend?

Answer
It would depend on the alarm installed.
You can add a microwave motion sensor, or
pin switches at key points, to the exsisting
alarm triggers, to cover the bed area.

But as I said, depends on the system you have now.

Hard to advise past this without particulars.
