Anti-theft device with cable attachment

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

• a housing with a first end of an electrically conductive strap attached to the housing, the housing having an opening for a second end of the conductive strap, the conductive strap configured to secure the theft detection device to the merchandise product, wherein the theft detection device is activated when the second end of the conductive strap is inserted into the opening;
• a light sensor disposed within the housing, the light sensor configured to sense an amount of light shining on the theft detection device;
• a motion sensor disposed within the housing, the motion sensor configured to sense movement of the theft detection device;
• an emitter disposed within the housing, the emitter configured to provide audio signals to a user;
• a microcontroller disposed within the housing, and coupled to the light sensor, motion sensor, and emitter, the microcontroller configured to control the emitter to emit an alarm signal based on data from the light and motion sensors, the microcontroller further configured to cause the emitter to emit the alarm signal when the conductive strap is cut or loosened from the merchandise product;
• and
• a decode switch which, when closed, opens an installation switch to deactivate the theft detection device.
