Flock’s network of automatic number-plate reader cameras is facing mounting opposition in the United States over privacy, surveillance and police misuse concerns. The company says it will tighten safeguards after reports that officers used its tools to stalk former partners and other people, while several communities have cancelled contracts or switched cameras off.

More than 120,000 Flock cameras use AI to identify vehicles by registration plate, make, model and colour, enabling movement tracking across interconnected systems. Los Angeles has paused use of 138 police-mounted cameras while seeking clearer data rules, Amazon-owned Ring ended a partnership with Flock following online criticism, and incidents have included a man wrongly treated as a suspect over supposedly stolen plates and alleged vandalism of cameras in Tennessee.
