Abstract
An anti-theft proximity alert system that includes a wearable smart charm with a charm housing having a button for the wearer to manually cancel a triggered sensory alert sequence. The object monitor may include within its housing a motion detector that monitors the state of motion of the object monitor, and at least one operating instruction that adjusts a property of the transmitted proximity signal in response to a change in the object monitor's motion state. A silent alarm of vibration and/or light on the charm housing perceptible to the wearer of the smart charm may be activated prior to the activation of an auditory alarm.
