Camwarn
License plate readers, briefly
An automatic license plate reader photographs plates and turns them into text. That is a different device from a speed-enforcement camera, even when they share a pole.
On this map, a Flock pin means the public map record names Flock Safety. Other manufacturers, and records with no manufacturer at all, use the other-ALPR layer. The split follows the source text. It is not a judgment about who operates the device.
OpenStreetMap locations are contributed by people who can see a device from a public place. They can be wrong, incomplete, or out of date. Camwarn does not operate readers, does not collect plate numbers, and does not show where a vehicle has been.
FlockHopper and DeFlock draw camera pins from OpenStreetMap and from community reports. Camwarn queries OpenStreetMap itself and does not copy their tiles. FlockHopper's terms also disallow automated collection from their servers. A community report stays in the review queue. Approving it does not add a pin.
Agencies, not pins
The Electronic Frontier Foundation Atlas of Surveillance lists agencies that have used a technology. The extract retrieved 2026-10-24 has 4,094 automated license plate reader records. 2,624 of those name Flock Safety. 1,134 do not name a vendor. These records have no camera coordinates, so they are not on the map. A missing agency is not a claim that the agency has no readers. The written summaries in the atlas were not copied.
