Abstract: It is disclosed a theft-detection assembly for detecting the theft of an item, the theft-detection assembly comprising: a wireless power transmitter configured to broadcast electromagnetic waves within a given area; a locator device configured to be associated with the item and comprising a wireless power receiver configured to receive the electromagnetic waves. The locator device further comprises an actuating unit and an alarm unit, wherein: the actuating unit is connected to the wireless power receiver and is configured to, in the absence of the electromagnetic waves, actuate the alarm unit; and the alarm unit comprises a radio module configured to, upon actuation, transmit an alarm message over a wireless communication network.
