Theft Detection Device and Method for Controlling Same

A theft detection device configured to be coupled to a product, comprising:

• a light sensor;
• a motion sensor;
• an emitter configured to emit a signal;
• and
• a controller coupled to the light sensor, the motion sensor, and the emitter;
• wherein the controller is configured to determine a light level sensed by the light sensor;
• wherein the controller is configured to determine, via the motion sensor, whether the theft detection device is in motion;
• wherein the controller is configured to operate the emitter based on the sensed motion of the theft detection device and the light level sensed by the light sensor;
• and
• wherein the controller is configured to enter the theft detection device into a sleep mode when no motion is detected for a predetermined period of time.

• and
• wherein the controller is configured to wait for a predetermined period before causing the emitter to emit a signal if the light level sensed by the light sensor is below a threshold level, or if motion is detected by the motions sensor.
