ViewScan is the most technologically advanced passive walkthrough Concealed Weapons Detection System. Its easy-to-use, PC-based software displays and tracks those who are carrying threat objects. ViewScan’s sensor technology accurately detects the location and number of threat objects such as knives, guns and razor blades, while ignoring personal artifacts like coins, keys and jewelry; it can also detect and locate threat objects which have been covered or masked with materials such as aluminum foil, lead and plastic.

Every person safely passing through the portal is scanned and can be archived with the following data: snapshot image of the person, date and time, threshold settings, sensor readings, graphical display. Archiving can be controlled at the workstation with the flexibility to monitor anyone entering or leaving a building including after hours.

Sensing Technology

ViewScan uses advanced magnetic sensors with on-board digital signal processing. The sensors communicate with patented software that spatially locates threat objects. ViewScan discriminates threat objects from non-threat objects by measuring the differences in total metallic mass and ferromagnetic composition. When a threat object or multiple threat objects are discovered, a yellow dot is superimposed over a real-time snapshot image of the person walking through the portal. A graphical display of the sensor data automatically scales the signal strength of individual sensors and cross-references them to the video image.

ViewScan set up at the Bank of America Annual Shareholder Meeting in Charlotte, NC.

ViewScan’s threshold or sensitivity/selectivity settings are linear as opposed to segments or ranges that screen specific targets. The portal operator has access to specific threshold setting accessible at the control console. Threshold settings can be changed without interrupting traffic flow while effectively detecting threat objects (guns, knives, box cutters, razor blades, etc.). Non-threat objects (keys, coins, jewelry, belt buckles, etc.) are permitted to pass without false alarms.
