These are used at entrances of buildings for the passage control of parcels, luggage, bags and other similar objects to detect any weapons or explosives and to ensure therequired security level for the building. The dimensions of the tunnel may vary between82 cm x 65 cm and 80 cm x 100 cm depending on the intensity of the passage of luggage of the building. Thanks to the two-dimension detection system, all of the objects passing through the tunnel can be checked without any loss of image on the edges. They are able to see through 29-mm-thick steel.
The main property of the X-ray security screening systems is their capability of distinguishing colors and of isolating images by using organic/inorganic doublemonitorsto make the distinction between organic and inorganic matters with four colors to detect organic-based explosives. These detectors give a sound alarm upon detection of a suspicious piece of luggage and record the passages exhibiting a high alarm level in a digital recording device by means of a camera and transmit the data into a database.
