Almost two months after originally intended, security measures at the disposal of the Olympic organising committee, there to ensure the safety of the Games, have been activated. The high-tech system, ordered from an American company at a cost of 255 million euros, was successfully tested at the 2002 Salt Lake City Winter Games. Named C41, the software will integrate a host of surveillance cameras with security organisations, including police, fire services, coastguards and the Ministry of Defence, cutting response times to a minimum. Greece has spent a record 1.2 billion euros on security, and will mobilise 70,000 police and army units, as well as six Patriot–type anti-aircraft missile batteries, stationed at the Tatoi military airport in the North of Athens.
