Systems and methods of device-free motion detection and presence detection

摘要

Systems and methods are provided for device-free motion detection and presence detection within an area of interest. A plurality of nodes, configured to be arranged around the area of interest, form a wireless network. The plurality of nodes transmit wireless signals as radio waves and receive transmitted wireless signals. The received signal strength (RSS) of the transmitted wireless signals between the plurality of nodes are measured and a value is reported. A computing device receives the reported values for the measured RSS and tracks the reported values over time. The computing device processes the reported values using an aggregate disturbance calculation to detect motion and presence within the area of interest. The computing device may notify notification device of a detected disturbance within the area of interest.
