Police explain ALPR (Flock) camera program, residents raise privacy questions

The Universal City Police Department presented details of its automatic license-plate reader system (ALPR, known commercially as Flock) and defended operational safeguards, audit controls and law-enforcement benefits while residents raised constitutional and privacy concerns.

Chiefs and supervisors explained the system’s three modes of use: alerts from a state database (stolen vehicles, missing persons, amber alerts), investigator‑requested searches tied to active case numbers, and hot-list entries for specific suspect vehicles. The department said there is no continuous “live” surveillance feed available to officers; the system records images at camera locations and produces a photo and timestamp when a vehicle passes a camera.

Department staff stressed that all searches require a case number (a mandatory field) and that hot-list creation is restricted to supervisory or detective-level administrators. They described an internal auditing process and a public-facing transparency portal on the city website that displays counts (the department reported roughly 229,000 photos captured, 212 alerts and 86 recorded searches in the system’s recent window). The department cited recent investigative successes attributed to ALPR use, including arrests in robberies and a counterfeiting/fuel‑theft ring.

Residents and council members questioned privacy risks and potential for misuse. Commenters cited lawsuits in other jurisdictions and said long-term, warrantless tracking of vehicles may be unconstitutional; the department replied that courts have repeatedly held there is no reasonable expectation of privacy for license plates in public and compared ALPR to discrete event-based camera detections rather than continuous personal-location tracking.

Council discussion focused on oversight and access controls. Staff said any agency sharing or receiving alerts must follow policy; the system’s value increases with network size (nearby agencies can detect vehicles that move across jurisdictions). Staff offered to review access lists and consider narrowing administrative hot-list privileges or otherwise tightening internal user pools while preserving timely investigative capability.

Why it matters: ALPR systems are increasingly deployed in small and large cities. Residents asked for transparency and for clear limits on who can create hot lists or perform searches; the department described mandatory case-number fields, audits and a public transparency portal as safeguards.

Key details - System deployment: 12 cameras, concentrated at points of entry and higher-crime areas. - Accountability: searches require a case number; hot-list creation restricted to sergeants or detectives; transparency portal available on city website. - Usage snapshot cited by department: ~229,000 photos, 212 alerts, 86 searches (recent window reported by transparency portal).

No ordinance or policy change was adopted at the meeting; council requested staff consider whether to narrow administrative access and to continue audits and public reporting.
