Surveillance Startup SignalTrace Expands License Plate Readers to Track Phones and Wearables

SignalTrace, a new surveillance product, correlates Bluetooth signals from smartphones, AirPods, and smartwatches with license plate reader data to link specific devices and individuals to vehicles. The technology aggregates multiple data streams—license plates, Bluetooth signatures, and nearby personal devices—to create comprehensive tracking profiles of people and their movements.

Why it matters: Privacy advocates and security professionals need to understand how surveillance infrastructure is expanding beyond traditional cameras and license plate readers into personal device ecosystems, raising significant concerns about consent and data collection practices.
