Homeland Security Conference

Latest in security technology on display at gathering for homeland security experts

A big homeland security conference and trade fair is going on in Washington today, bringing together federal, state and local security experts -- and the vendors who hope to supply them. In the market for inflatable isolation chambers or personal climate control suits just in case of a chemical attack? They're on display. How about "smart" id cards that store reams of information authenticating your employees? They're being offered too. Also on display at the Washington DC convention center -- a new field screening test for anthrax and ricin, a jammer for radio-controlled bomb devices, and a machine that can sniff a suitcase for chemcials and explosives while x-raying it at the same time. The conference and the trade show conclude tonight.
