Trucks, trains, ships and oil rigs are all potential targets for criminal organizations. Organizations that own, use or transport high value assets recognise the need to protect their goods and employees, especially when they are at their most vulnerable - when in remote or isolated situations, at night and when operating alone. By their very nature, trucks, trains, ships and oil rigs are all potential targets for criminal organisations. Furthermore, monitoring systems, early warning and deterrent technology have not been available to address this need at a remotely affordable cost.
