Abstract
A system for detecting electronic article surveillance marker shielding includes electronic article surveillance (“EAS”), metal detection and video analysis subsystems communicatively coupled to a system controller. The EAS subsystem detects EAS markers within a detection zone. The metal detection subsystem detects metallic objects within the detection zone. The video analysis subsystem captures a video image of the metallic object. The system controller determines a probable classification for the metallic object and calculates a confidence weight for the probable classification. If the metallic object is identified as EAS marker shielding according to the probable classification and the corresponding confidence weight, an alert is generated.
