The FSC HPD system detects any movement generated by a hidden person or persons that is in contact with the interior or cargo of the vehicle. Even signals such as a person’s heartbeat can be detected. Hidden persons motion and human heartbeat are detected with the use of sensitive sensors attached to the vehicle either in a horizontal or vertical position. From the sensors, data is sent via cable to a computer, where the measured data is subjected to stringent analysis and subsequent evaluation. The measurement time is approx. 30 seconds while the total vehicle check time does not exceed 2 minutes, including application and removal of the sensors.
Fare dodgers, illegal immigrants or terrorists may be transported in lorries or trucks from one country to another without meeting the legal requirements to enter these countries. Trucks are often sealed or loaded in such a way that renders standard visual check of the cargo space impossible. Responsible authorities keep fighting against transport of hidden persons. Not all methods, as e.g. measurement of CO2 concentration or X-raying of cargo spaces of trucks are reliable in all cases and can be sometimes circumvented.
HPD is a simple, non – invasive measurement method. It is passive detection that does not have any side effects for the human organism or equipment in its vicinity. It is the latest generation of a detector of hidden persons that makes it possible to reveal hidden persons with almost 100% reliability in less than 1 minute.
Thanks to three design versions, vehicles can be checked not only in permanent locations such as ports and border crossings and entrance gates of sites, but also in the field where checks may move.
