Flock sent 1,427 alerts to Roseville police over two years, flagging cars as stolen or used in a felony. In 71% of them, Flock read the plates wrong.

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.”

    …yes?

    The cameras around the US scan 7000 plates per second, trying to figure out what they say with 8000 different possible plate designs around the country, and those results are then matched to a database of stolen vehicles and other plates , which there’s roughly 600k reported stolen in the US each year so. That database is going to be massive.

    That means every second, 7000 strings of letters and numbers OCR’d at unknown conditions and accuracy are being compared to hundreds of thousands of stolen plates. They are guaranteed to get a number of “matches” constantly, most of them from reads that were not accurate.

    And specifically because they aren’t sent anywhere, nobody can double check the picture to see if the camera got it anywhere right at all.

      What does any of this have to do with the cameras from one specific town being wrong a majority of the time? Not that it would be better if it wad the average across the nation. It would be much, much worse actually.
