Abstract:
1. A system for motion detection and presence detection within an area of interest, comprising: a plurality of nodes configured to be arranged around the area of interest and automatically form a wireless network, wherein each node of the plurality of nodes transmits wireless signals as radio waves to other nodes of the plurality of nodes, receives the transmitted wireless signals from other nodes of the plurality of nodes, and measures received signal strength (“RSS”) of the transmitted wireless signals received from the other nodes of the plurality of nodes, wherein each node of the plurality of nodes reports values for the measured RSS of transmitted wireless signals received from the other nodes of the plurality of nodes; and a computing device in communication with the plurality of nodes to receive reported values for the measured RSS of the transmitted wireless signals between the plurality of nodes and track the reported values over time, wherein the computing device processes the reported values using an aggregate disturbance calculation to detect motion and presence within the area of interest, the aggregate disturbance calculation based on a plurality of values for the measured RSS over a period of time.
