Flock misread license plates in 71% of the alerts it sent to police in one California town

In 2023 and 2024, Flock sent 1,427 alerts to the Roseville [CA] Police Department.

Roseville police found that Flock misread license plates in 71% of those alerts.

Max Isaacs, director of technology law and policy with the Policing Project at New York University’s School of Law, described Roseville’s misread data as “stunning.”

“A 71% misread rate is really beyond the pale,” he told Business Insider, referring to Roseville’s reported error rate for stolen and felony vehicle alerts. He added that “in the absence of concrete rules that directly address the problem of misreads, this technology is not safe to be deployed in communities.”

If you have a pi reading license plates, you are probably scanning a few dozen different plates a day, looking if they match a handful of possibilities. If the only plate that opens the gate is ABC123, nothing happens if it accidentally reads anything else, and I’ll probably get it right a second later.

When Flock scans plates, it reads thousand of them every second looking to read and match every possible plate variation from every state (which there are over 8000 of) to every reported stolen plate, in all weather and lighting conditions. It’s really no wonder if 71% of the times it reports it found a stolen plate it had got it wrong.

I don’t think you understand their point. The point is that the OCR can be done on a distributed system, because a distributed system is what the cameras already are.

My biggest contention with this claim is whether the computers onboard the license plate readers are actually capable of doing this with solar power and battery capacity, but considering I’d rather they didn’t exist anyway…
