Flock says that in optimal conditions, its cameras accurately read more than 96% of license plate characters. Hundreds of pages of records from the Roseville Police Department show a different picture. In 2023 and 2024, Flock sent 1,427 alerts to Roseville police, flagging vehicles as stolen or used in a felony after they passed one of the city’s Flock cameras. An analysis by the police department found that in 71% of those alerts, Flock’s machine-learning software incorrectly read the license plates.
Business Insider filed public-records requests to obtain email correspondence, data, meeting notes, contracts, and other records that reveal the extensive back-and-forth between Roseville and Flock over repeated errors by Flock’s system. The cameras regularly missed vehicles, captured blurry images, misread license plate characters and states, and sent delayed alerts to police about vehicles possibly connected to crimes, the records show.
Roseville — which, Flock noted, has an atypical setup for its cameras— has flagged problems to the startup dozens of times over the past four years. The department said it has reported issues to the company as recently as this year, and it continues to meet with Flock twice a month to provide updates and share concerns.
