An auto-calibrated proximity sensor used with a protected item in a retail display security system includes a metalized surface that cooperatively interacts with a printed circuit board to form a capacitive cell. A microcontroller senses changes in the frequency of the capacitive circuit if the orientation of the metalized surface changes with respect to the printed circuit board.

Auto-calibrating proximity sensor for retail display security system

A powered item attachment device includes an onboard power supply and alarm system that sounds in the event a protected device is tampered with or removed from a retail display. The powered item attachment device may also track the location of a protected device if it is removed from the display device.
