Abstract :
Semiconductor detectors have been used in counter surveillance for many years. The principle should now be used for the detection of semiconductors (in electronic devices like mobile phones, transmitters, or tape recorders) carried by persons into or out of security areas. Therefore known system elements and components are to be integrated into walkthrough sluices. First outcomes and a prototype are described in this paper.
