Abstract
Systems and methods for operating an EAS detection system. The methods comprise: detecting an Active Security Tag (“AST”) in an EAS detection zone; determining whether AST is coupled to an object identified in a list; and performing operations when a determination is made that AST is coupled to a listed object. The operations involve: accessing sensor data generated by at least one sensor device disposed on/near display equipment associated with the listed object; processing the sensor data to determine whether a person was within a defined distance range of AST during a period of time immediately preceding the detecting; concluding that a false alarm scenario exists when the sensor data indicates that a person was not within the defined distance range of AST during the period of time; and suppressing alarm issuance by the EAS detection system in response to the false alarm scenario conclusion.
