What Flock cameras actually are
Flock cameras are automatic license plate readers (ALPR). They photograph a plate, record the time and location, and match it against databases. Flock Safety reports roughly 120,000 cameras across 49 states — see the state-by-state tracker. They do not measure speed (full answer) and do not record continuous video by default.
The core privacy concern
A license plate is effectively a vehicle's ID. Photographing every plate that passes means tracking everyone, not just people on a watchlist. That produces a searchable location history for each plate — and how long it is kept is usually a local policy choice (how long plate data is kept).
Who sees your data
Access is not limited to your local police. Subscriber agencies share data, and there are reported examples of out-of-state agencies accessing California plate readers. Exactly who can query the network, and how often, is rarely disclosed. See who can access Flock data.
Stalking and abortion-access concerns
Because plate data is a location history, privacy advocates warn it can be misused to track specific people — a concern that maps onto stalking risks and cross-state abortion-access concerns. Google Trends shows searches for these topics surging alongside the Flock controversy.
The backlash is real and growing
As of August 2026, 23 jurisdictions have canceled Flock contracts, an Illinois city ordered cameras removed, and dozens of cameras have been stolen or vandalized. Follow the ban tracker for the latest, or read about the vandalism wave.
