Abstract
Integrating a direct current (DC) voltage motion sensing alarm with an alternating current (AC) voltage light source is presented herein. An apparatus can include a voltage conversion component that generates, within a wall switch box, a DC voltage from an AC voltage that is higher in magnitude than the DC voltage, and a motion sensing component that detects, from the wall switch box using the DC voltage, a motion of an object. The motion sensing component can detect the motion using an infrared and/or ultrasonic based DC sensor. The apparatus can further include a security component that generates, from the wall switch box using the DC voltage, an alarm signal and/or wireless alarm signal based on the motion, and a power component that switches, from the wall switch box using the DC voltage based on the motion, the AC voltage from a first contact to a second contact.
