Delta R

With the help of light reflection we detect illicit traces. That explains the name, we look at the different (Delta) of the reflection (R ) upon a surface. Our software calculates the difference in wavelength between two images and determines whether the detected substance is illicit or not.

Echo X

The Echo X technology encompasses a Through Barrier Analysis at a specific point by means of X-ray imagery. An ideal technology for HBS, where bags can be scanned more efficiently without interference of man, and by means of intelligent software, resolve alarms.
