Traffic Cameras Now Track Your Phone

Our Take

Credit to TekSnax for flagging this one early. If Leonardo US Cyber and Security Solutions is really bolting phone-signal detection onto existing ALPR camera networks, that's a meaningful escalation. The entire pitch for license plate readers has always been "we're just reading what's already public, a plate on a public road." Tying that same roadside hardware to device identifiers moves the technology from tracking cars to tracking people directly, phone in pocket, whether or not they're even driving.

This matters because ALPR infrastructure was sold to city councils as a narrow tool for stolen cars and AMBER alerts, not as a backbone for phone-level location tracking. Once a camera pole can log a MAC address or IMSI alongside a plate and timestamp, you've built a far more precise surveillance net, one that follows pedestrians, passengers, and anyone who walks or bikes past the sensor, not just drivers. History with this industry suggests capability creep is the default: features built for one justification get repurposed, bundled into data-sharing agreements, and handed to agencies with little public debate before anyone notices the upgrade happened.

We don't have independent confirmation of SignalTrace's technical specifics yet, so treat early claims with appropriate skepticism until more documentation surfaces. But the direction of travel is clear, and it's worth checking whether this kind of hardware is already near you.
