Securing transport vehicles against theft of their contents enables unauthorised unloading to be detected and countermeasures taken or information stored

摘要

The method involves signalling the opening of a loading container door, lowering of a loading board (6) or similar, or an attempt to open the vehicle to a control circuit (2) for verification by correlation with at least one independent signal (4,11). If appropriate the access is locked (9) or re-closed, vehicle functions are blocked, an alarm is triggered and recordings are made (3).
