A radio system tracking can automate the tracking of an electronic tag device (ETD) by identifying the ETD's signal identifier and then perform a tracking function to determine a general position of the ETD. Over time, as the ETD moves and a computer vision system monitors and tracks the device location, the radio position tracking of the ETD and the computer vision position tracking of the ETDs will eventually converge and the computer vision can then determine that the ETD in the camera view is the same ETD communicating with the radio tracking system.
