ABSTRACT:
Alarm systems, remote communication devices, and article security methods are described according to some aspects of the disclosure. In one aspect, an article security method includes associating a remote communication device with an article to be secured; using the remote communication device, generating a plurality of electrical signals responsive to receipt of spurious electromagnetic energy and a plurality of wireless signals of a base communication device associated with the remote communication device to form an alarm system; distinguishing the electrical signals generated responsive to the spurious electromagnetic energy from electrical signals generated responsive to the wireless signals of the base communication device; and responsive to the distinguishing, generating a plurality of human perceptible alarm signals corresponding to respective ones of the electrical signals generated responsive to the wireless signals of the base communication device.
