ABSTRACT:
A personal article anti-theft system includes a base retained on a surface and a hook connected to the base so that it can hang downward. A detection circuit is located within the base and is connected to the hook so as to detect the presence of an item on the hook. If the item is removed from the hook without authorization, e.g., during a theft, an alarm circuit operatively connected to the detection circuit will sense the removal of an item. If the alarm circuit is in a set condition, the removal will generate an alarm signal. The resulting alarm signal is received at a remote alarm detection circuit located at a distance from the base. Receipt of this signal causes the remote alarm to produce a humanly perceivable indication of the alarm.
