130,000 AI Cameras Are Reading Your Licence Plate Right Now
A private company called Flock Safety has blanketed the United States with AI-powered licence-plate readers, mostly for police use. Critics say the network has grown faster than the laws meant to govern it.
Key points
- Flock Safety has deployed approximately 130,000 AI licence-plate reader cameras across the United States.
- The cameras are used primarily by law enforcement agencies to track vehicles in real time.
- The rapid expansion has triggered privacy protests and calls for tighter legal oversight.
- No federal law currently governs how long Flock or its police clients can store the data the cameras collect.
Every time you drive past one of Flock Safety's small, pole-mounted cameras, it photographs your licence plate, runs the image through an AI system (software that can recognise patterns the way a human eye does), and logs where your car was and when. Do that in enough American towns and you have something close to a continuous map of where millions of people go every day.
There are now around 130,000 of these cameras operating across the country, most of them under contracts with local police departments. BBC News first reported the scale of the rollout earlier this year.
How does the system actually work?
Flock's cameras do more than read number plates. Each unit also notes a vehicle's make, colour, and any visible features such as roof racks or bumper stickers, building what the company calls a "vehicle fingerprint." Police can search the database for a plate, a colour, or a partial description and pull up a list of sightings within seconds.
The pitch to police is straightforward: find stolen cars faster, solve crimes with less legwork. Many departments report genuine results. A camera outside a petrol station has no officer costs, no coffee breaks, no sick days.
Should ordinary drivers be worried?
Possibly, yes. The concern is not really about catching car thieves. It is about what happens to the data once it exists.
Privacy advocates point out that Flock's network can, in practice, reconstruct a person's daily routine from nothing more than their number plate. Drive to a hospital, a place of worship, a political rally, or a lawyer's office and that trip may sit in a database for months. Most states have no specific law capping how long the records are kept or who can request them.
Protests have broken out in several cities where residents discovered cameras had been installed without public consultation. Some local councils have since voted to remove them.
| Fact | Detail |
|---|---|
| Cameras deployed | ~130,000 |
| Primary clients | US law enforcement agencies |
| Data captured | Plate, make, colour, distinguishing features, time, location |
| Federal data-retention law | None currently in place |
| State-level rules | Vary widely; most states have no specific cap |
Flock Safety argues its system is used strictly within legal boundaries and that it helps solve serious crimes. The company also says individual agencies set their own data-retention periods.
That last point is part of the problem. Oversight is patchwork. One town might delete records after 30 days; a neighbouring county might keep them indefinitely.
What can residents do?
Check whether your city or county has a Flock contract. Many local governments post procurement records online, and some have held public hearings after residents asked. If your area has an elected council or city board, attending a meeting and asking about data-retention policy is a direct route to an answer.
If you are in a state considering licence-plate reader legislation, contacting your state representative costs nothing and does have an effect: several states have tightened rules after constituent pressure.
The cameras are not going away. The question being fought out right now, town by town and statehouse by statehouse, is whether the rules governing them will catch up before the network grows much larger.
Common questions
Can I find out if I have been tracked by one of these cameras?
In most US states, you can file a public-records request (a formal written demand under freedom-of-information law) with your local police department. Whether they must release the data varies by state.
Are these cameras legal?
Yes, in most jurisdictions. Filming public roads is generally lawful. The legal disputes centre on data storage, who can access the records, and whether residents must be notified before cameras are installed.
