Bob Eldridge of Summertronics has invented an innovative product called the Scanthief 200 to help in the fight against caravan crime. It basically consists of a tiny transmitter you hide in the caravan.

There is a case station that you leave at home or work and in the instance of somebody tampering with the van the station will give off an alarm to alert you.

The device is just four-and-a-half inches by two-and-a-half inches and detects movement in any direction.
