Abstract
A wireless security system includes a power supply and a security device in selective electrical communication with the power supply. The security device provides a security response when electrically connected with the power supply. A receiver is electrically connected between the power supply and the security device and is operable to selectively electrically connect the security device with the power supply. At least one self-energizing switch of the system includes a wireless transmitter and an energy harvester that is operable to power the wireless transmitter. The wireless transmitter emits a signal to the receiver in response to power from the energy harvester, to trigger the security response.
