Mountain View, California disabled its network of 30 Flock Safety automated license plate reader (ALPR) cameras after discovering that Flock enabled data-sharing/search features that allowed other agencies to access the city’s license-plate data without authorization. City officials said a “statewide lookup” capability had been active across 29 of 30 cameras for about 17 months, enabling hundreds of California law-enforcement agencies to query Mountain View’s database; the issue reportedly surfaced during preparation for a public-records response. Police Chief Mike Canfield said the cameras will remain off pending a City Council discussion, and stated he opposes reactivating the system due to lost confidence in the vendor’s access controls and transparency.
A second issue involved a “national lookup” setting that was allegedly enabled on at least one camera without the city’s knowledge, potentially exposing data to out-of-state and federal agencies in a manner that could conflict with California restrictions on sharing ALPR data (including limits on sharing with out-of-state/federal entities and use for immigration purposes). Mountain View Police said there were no records retained from the period when national lookup was enabled, limiting the ability to determine what data may have been accessed or transferred. The incident has heightened scrutiny of ALPR governance and vendor-controlled configuration, particularly where local policy and state law require explicit authorization and auditability for any cross-agency data access.

City officials said the cameras would stay offline until the Mountain View City Council discusses the matter at a scheduled meeting. The meeting was set for February 24, 2026, to consider the future of the city's relationship with Flock.
Flock Safety responded that it was working with Mountain View to resolve the issue and expressed hope that the partnership could resume. The statement came after the city suspended the camera network over unauthorized data access.
After uncovering the unauthorized sharing, the Mountain View Police Department disabled its network of 30 Flock Safety cameras. Police Chief Mike Canfield said the cameras would remain offline and that he opposed reactivating them because of lost confidence in the vendor.
While responding to a public records request, Mountain View police discovered that Flock had enabled unauthorized sharing mechanisms, including statewide and national lookup access. The finding revealed that outside agencies, including federal or out-of-state entities, could query city ALPR data without authorization.
Flock Safety enabled a statewide lookup feature on 29 Mountain View ALPR cameras for about 17 months, allowing hundreds of California law enforcement agencies to search the city's license plate data without a data-sharing agreement or city permission. Reporting indicated more than 250 agencies conducted an estimated 600,000 searches in a year through this feature.
Mountain View later determined that one Flock Safety ALPR camera was made accessible to out-of-state agencies from August through November 2024, despite California restrictions on such sharing. The city said it had not authorized this access and Flock kept no records showing what data may have been queried during that period.
