Abstract
A method for detecting an event in or around a building. The method includes recording a baseline signal characteristic that characterizes a wireless signal transmitted between devices in or around the building during a baseline time period and recording a second signal characteristic that characterizes the wireless signal during a second time period after the baseline time period. An event in or around the building is detected in response to a determination that the second signal characteristic is abnormal relative to the baseline signal characteristic, the event degrading the wireless signal during the second time period. An alarm is triggered in response to detecting the event.
