Prying eyes: Crime-fighting camera sees through clothes to spot weapons

What's billed as the first camera able to see concealed weapons is now on the market.

Its developer, Brijot Imaging Systems Inc., Orlando, Fla, uses passive millimeter-wave-sensor technology from Lockheed Martin to detect guns, knives, and bombs, whether metal, plastic, or composite, concealed beneath a person's clothing.

The Brijot system uses a millimeter-wave camera combined with a video camera. The system images millimeter-wave signatures and compares them via software to its database of weapons. It can interface with other security devices such as door-entry systems and video-surveillance systems. The outputs are real-time video that lets operators see the suspicious items, and an electronic alarm that signals up to 50 threats simultaneously. Maximum range is 45 ft.
