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.
