Filtering and correlating radio signals based on a field of view of a camera

Abstract

Architectures and techniques are presented that can record video data and wireless communication device data. Signals from sources outside a field of view of a camera recording the video data can be filtered. Such can affect a shielding technique in which a signal shielding apparatus is adjusted in orientation based on an orientation of a camera device. Techniques are further presented to synchronize, according to time, video data and device data. Such synchronization can allow for improved correlation between visual objects (e.g., recorded by the camera) and radio objects (e.g., recorded by a transceiver). For example, visual techniques can be employed to estimate distance/locomotion of a visual object, whereas signal strength metrics can be used to estimate distance/locomotion of a radio object, and the relationship between the two can indicate a strong correlation that a particular device ID is linked to a particular visual object and vice versa.
