Systems and methods for wireless surveillance

A system comprising:

• input/output circuitry configured to:
• initiate a wireless link between the first wireless device and the second wireless device;
• processing circuitry configured to:
• evaluate CSI of the wireless link to determine relative locations of the first wireless device and the second wireless device, wherein the processing circuitry configured to evaluate the CSI of the wireless link is further configured to:
• evaluate a first direction of the wireless link between the first wireless device and the second wireless devices via first time rate-of-change data for the first direction;
• and
• evaluate a second direction of the wireless link between the first wireless device and the second wireless device via second time rate-of-change data for the second direction;
• based at least in part on the evaluating the CSI of the wireless link, select the first wireless device, the second wireless device, and the wireless link to perform a monitoring routine;
• control the first wireless device and the second wireless device to perform the monitoring routine to determine a relative position and a movement of an object, wherein performing the monitoring routine comprises evaluating third time rate-of-change data of the wireless link;
• and
• generate, for output, an indication of the movement and relative position of the object.
