<p>A security device may include an attachment assembly configured to affix the security device to an object, a locking assembly configured to lockably secure the attachment assembly and configured to transition between at least a locked state and an unlocked state, a transformer configured to drive an alarm assembly to generate an alarm, and processing circuitry. The transformer may be further configured to operate as a wireless receiver to receive a remotely transmitted wireless signal. The processing circuitry may be configured to monitor an output of the transformer to determine whether the wireless signal has been received via the transformer, and selectively activate the transformer to drive the alarm assembly to generate the alarm.</p> |
