Our Take

This is exactly the kind of grassroots tooling that keeps the fight against mass ALPR surveillance alive: a hobbyist outfit building purpose-made hardware so ordinary people can drive around and flag Flock cameras instead of relying on leaks, FOIA requests, or whatever scraps law enforcement agencies choose to disclose. Credit to Valleytech Custom Solutions for turning an ESP32 board into a dedicated wardriving kit — it lowers the technical barrier for anyone who wants to contribute real data to the public record.

Projects like this matter because Flock Safety and similar vendors have built an enormous, largely invisible network of license plate readers with almost no public accounting of where they actually are. Crowdsourced hardware turns that opacity into something trackable, and every camera logged is one more data point that journalists, lawyers, and privacy advocates can use to push back on unchecked deployment.
