n the summer of 2024, a police officer
in the Sacramento suburb of
Roseville, California, called a man to
discuss a persistent problem with his
license plate.
THE CAMERAS WERE
MADE BY FLOCK,
SCANNING COMPANY.
Roseville Police Department, identifying
his vehicle as stolen or used in a felony
crime. Roseville police could see that
Flock's software kept confusing the "9" on
the man's license plate for an "8."
The car owner said he would take off his
license plate cover. Soon after, it happened
again.

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 re-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, and 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.
