The latest surveillance, defence and security equipment is presented by the 60 exhibitors at MS&D 2009, the international conference and exhibition on Maritime Security & Defence (MS&D), to be held at the Hamburg Fair site from 30 September to 2 October 2009. The exhibits include sophisticated optical and acoustic sensors, which have substantially improved the automated monitoring and control technology of security and defence equipment and systems. Thus the exhibiting companies, most of them from the exclusive circle of defence system manufacturers, are contributing to the protection of international shipping. A trend at MS&D 2009 is unmanned aerial vehicles (UAVs) which fly in fully automated mode and can be used for surveillance. The exhibits by Diehl BGT Defence GmbH & Co.
