Container surveillance system and related method
First Claim
1. Mobile communication device for surveillance of at least one transported unit being carried by a transporting unit, comprising:
- a short range data communication unit adapted to a short range wireless data exchange with at least one tag attached to the transported unit;
a long range data communication unit adapted to a long range wireless data exchange to a transport surveillance system;
characterized in that the mobile communication unit is fixed to operating equipment of the transported unit or to the transporting unit during surveillance of the transported unit and is detachable from the transported unit or the transporting unit when the transported unit must not be surveyed.
