Concealed Object Detection

SNC's Remote Frisk™ system technology detects objects concealed on a person at a distance of 40 feet or more. The Remote Frisk operates out of a van or truck, covertly screening a crowd at a sports event. It can also be installed indoors to screen passengers in a terminal, at the entrance to a building, a shopping center, an office complex or visitors to a facility.

SNC’s Remote Frisk technology combines the best of active and passive detection approaches, eliminating the speckle problem and allowing  very low MMW radiating power to be used.
