Make a Flock Camera Detector in 60 Seconds
The short version: A hobbyist builds a $20 ESP32 gadget to sniff out Flock Safety cameras, showing just how cheap it's becoming to fight back against unchecked ALPR surveillance.
Our Take
Credit to littlehakr for turning a weekend curiosity into a 60-second build log: a wireless detector cobbled together from an ESP32 and a handful of cheap Amazon modules, aimed squarely at sniffing out Flock Safety's camera network. It's the kind of scrappy, open hardware project that matters precisely because it's replicable — you don't need a surveillance budget or a government contract to start pushing back, just a soldering iron and some curiosity.
What's notable isn't just the gadget itself, but what it represents. Flock's pitch has always leaned on the idea that these cameras are invisible infrastructure, quietly logging plates block by block with no real public accounting. When private citizens can build a tool in an afternoon to detect that infrastructure, it punctures the illusion that this surveillance is either untouchable or fully hidden. DIY detection won't solve the policy problem, but it shifts the power dynamic a little, and it adds to a growing toolkit of community-driven countermeasures.
If you want the bigger picture instead of a single camera ping, check our camera map to see how dense Flock's footprint already is in your area, and visit take action for ways to push your local council or school board to actually disclose and limit this data collection.
