Topic: Signal Trace

Signal Trace is identified as a commercial signal intelligence system that attaches to Flock Safety license plate reader poles to log Wi-Fi, Bluetooth, and RFID signatures. The technology creates unique digital fingerprints by grouping devices like iPhones, Apple Watches, and hearing aids that travel together, effectively tracking individuals even without facial recognition. Retailers like Walmart utilize these systems to monitor traffic flow and identify potential shoplifters in parking lots.

Flock Safety surveillance cameras are reportedly emitting 2.4 GHz radio signals that interfere with car Bluetooth audio systems. Some users claim their music cuts out specifically when passing these camera installations, which may also be equipped with "Signal Trace" technology to identify mobile devices and fitness trackers. The rapid, ubiquitous rollout of these cameras in residential and commercial areas is identified as a significant expansion of the surveillance state.
