WG 4C Passive Body Scanner

The WG 4C Passive Body Scanner detects metals, plastics, ceramics, liquids, gels and powders. It can be used as a standalone body screening system or incorporated into wider security architecture. WG 4C

The system uses a passive approach that ensures completely safe and non invasive screening by measuring the natural TeraHertz energy emitted by all individuals and their surrounding environment.

The WG 4C Passive Body Scanner uses aligned CCTV and TeraHertz cameras that provide the system operators with real time images of the individuals being screened.

The WG 4C Passive Body Scanner will screen stationary individuals at a distance of 3.5 metres, making it practical and convenient for security screening applications.

During installation the system is set at an angle 25 ˚, this angle enables full height screening of an individual to be optimally achieved; the floor pole on which the unit is deployed also serves to position the unit at the correct height. In combination, the installation angle and the height of the unit ensure optimal detection, with the focus being centred on the midriff of an individual.

The system is designed for indoor operations within an environmentally controlled facility; the unit is compact and portable, which makes it ideal for simple and rapid redeployment between locations as required.
