Abstract
Integrating a direct current (DC) voltage motion sensing alarm with an alternating current (AC) voltage light source is presented herein. A wall switch box can comprise a voltage conversion component that generates a DC voltage from an AC voltage that is higher in magnitude than the DC voltage, a motion sensing component detects a motion of an object using the DC voltage, and a security component that generates, based on the motion using the DC voltage, an alarm signal that has been encoded according to an encryption strength of a communication protocol corresponding to a transmission of the alarm signal from the wall switch box. In one aspect, a communication expansion component can wirelessly transmit, using the DC voltage based on control information specifying the communication protocol, the alarm signal according to the encryption strength. In another aspect, the encryption strength can correspond to at least 2128 combinations.
