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. ## Claims ### Claim 1 A wireless security system comprising: a power supply; a security device in selective electrical communication with the power supply, the security device providing a security response when electrically connected with the power supply; a receiver electrically connected between the power supply and the security device, the receiver selectively electrically connecting the security device with the power supply; at least one self-energizing sensor including a wireless transmitter and an energy harvester powering the wireless transmitter in response to a security event, the wireless transmitter emitting a signal to the receiver in response to being powered by the energy harvester, to trigger the security response; and a memory module in communication with the receiver and capable of recording an activity pattern of the security device over a time period, wherein the receiver selectively electrically connects the security device with the power supply over another time period to repeat the activity pattern as the security response. ### Claim 2 (depends on 1) The wireless security system as recited in claim 1, wherein the security device includes a building light, and the activity pattern includes alternating ON and OFF states of the building light. ### Claim 3 (depends on 1) The wireless security system as recited in claim 1, wherein the receiver includes the memory module and a software module identifying the signal with the at least one self-energizing switch. ### Claim 4 (depends on 1) The wireless security system as recited in claim 1, wherein the at least one self-energizing sensor is portable such that the security response can be triggered from different locations relative to the receiver and the security device. ### Claim 5 (depends on 1) The wireless security system as recited in claim 1, further comprising a motion sensor powered by the energy harvester, and wherein the energy harvester is a photovoltaic device. ### Claim 6 (depends on 5) The wireless security system as recited in claim 5, wherein the photovoltaic device powers the motion sensor. ### Claim 7 (depends on 1) The wireless security system as recited in claim 1, wherein the at least one self-energizing sensor is mechanically coupled to a building entryway selected from a window and a door. ### Claim 8 (depends on 1) The wireless security system as recited in claim 1, wherein the energy harvester is coupled with a building entryway such that the energy harvester generates the power in response to movement of the building entryway. ### Claim 9 (depends on 1) The wireless security system as recited in claim 1, wherein the at least one self-energizing sensor is coupled with a lock of a building entryway. ### Claim 10 A method for use with a wireless security system, comprising: recording in a memory module an activity pattern over a first time period for at least one security device; and selectively electrically connecting, with a wireless receiver, the at least one security device with a power supply to repeat the activity pattern of the first time period over a second time period, wherein the receiver is connected between the power supply and the security device. ### Claim 11 (depends on 10) The method as recited in claim 10, wherein the at least one security device includes a building light, and the activity pattern is a lighting pattern to simulate occupancy in a structure. ### Claim 12 (depends on 10) The method as recited in claim 10, further comprising generating the activity pattern by switching a building light between an ON and OFF states. ### Claim 13 (depends on 10) The method as recited in claim 10, including automatically recording the activity pattern over a predetermined rolling time period. ### Claim 14 (depends on 13) The method as recited in claim 13, including manually triggering the second time period to start, using a self-energizing switch.
