METAL DETECTION SYSTEM WITH INTEGRATED DIRECTIONAL PEOPLE COUNTING SYSTEM Russian patent published in 2015 - IPC G08B13/24 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to electronic article surveillance (EAS) systems. The system for detecting electronic article surveillance ("EAS") marker shielding includes an EAS subsystem (10), a metal detection unit (18), a people counting system (20), and a processor (16). The EAS subsystem (10) operates to detect an EAS marker in an interrogation zone. The metal detection unit (18) operates to detect a metal object in the interrogation zone. The people counting system (20) operates to detect one or more people in the interrogation zone. The processor (16) is electrically connected to the EAS subsystem (10), the metal detection unit (18) and the people counting system (20). The processor (16) is programmed to receive information output from the people counting system (20) and information output from the metal detection unit (18) to determine whether to generate an alarm signal based on the presence of EAS marker shielding.

EFFECT: enabling detection of EAS marker metal shielding in an EAS area.
