Abstract
A facility may include antennas directed to a known location and cameras with a field-of-view that encompasses the known location. The antennas acquire a device identifier and device data from a mobile device carried by a user at the known location. Antenna data is then generated to describe the data acquired by the antennas. Image data is also generated from the cameras to include images of a person at the known location. The antenna data and image data are then processed to determine estimated motion values and a comparison of such values is performed to check if such motion values are within a threshold of one another. If the motion values are within a threshold of each other, data indicative of presence of the mobile device at the known location is generated.
