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.
Systems and methods for operating an Electronic Article Surveillance ("EAS") system. The methods comprise: detecting movement of a plurality of security tags in a facility using Radio Frequency Identification ("RFID"); identifying which security tags of the plurality of security tags are moving towards an exit of the facility or are in a surveillance zone; determining a number of the identified security tags that are coupled to unsold objects; comparing the number to a threshold value; and causing the EAS system to issue an alarm when the number is greater than or equal to the threshold value.
Systems and methods for operating a tag detacher. The methods comprise: receiving a tag body of a security device in a nest of the tag detacher; actuating a detachment mechanism of the tag detacher so as to cause a release of a tack assembly from a securement mechanism located within the tag body of the security device; allowing the tag body to travel out of a nest by at least rotating a portion of the nest so that the nest transitions between a home position and a pivoted position; and returning the nest to the home position when the tag body no longer resides in the nest.
Systems and methods for operating a security tag. The methods comprise: causing a plunger of the security tag to engage a latch of the security tag; preventing, by an anti-defeat structure of the security tag, a disengagement between the plunger and the latch when an impact force is applied to the security tag; and allowing, by the anti-defeat structure, the plunger to disengage the latch when a magnetic field is applied to the security tag.
A system includes a plurality of first building components, a private local blockchain, a second building component, and a client device. The private local blockchain includes a device ledger indicating each first building component, a transaction ledger maintaining a plurality of blocks corresponding to a transaction between at least two first building components and including at least one first unique identifier of the corresponding first building component and a timestamp of the transaction, a transaction processor that generates at least one block by executing a predetermined hash function using a previous block, and a local rule engine defining rules to evaluate a transaction. The second building component has at least one second unique identifier. The client device provides the at least one second unique identifier to the private local blockchain. The private local blockchain determines whether to add the second building component to the device ledger.
