Automated License Plate Reader (ALPR) System

The Tiburon Police Department (TPD) utilizes automated license plate reader technology to convert data associated with vehicle license plates for official law enforcement purposes, including identifying stolen or wanted vehicles, stolen license plates, and missing persons. It may also be used to gather information related to active warrants, electronic surveillance, suspect interdiction, and stolen property recovery. 

The policy of the Tiburon Police Department is to utilize ALPR technology to capture and store digital license plate data and images while recognizing the established privacy rights of the public. To learn more about the Tiburon Police's use of automated license plate reader systems, read Tiburon Police's Department Policy on ALPRs linked below.

About the System

In July 2025, TPD transitioned its ALPR technology from the Vigilant system to the Flock system. The Town currently operates 8 Flock cameras around town. View Tiburon's Flock Transparency Portal for more information about Tiburon's Flock system, including which agencies we share data with. 

Data Privacy & Accountability

In compliance with Senate Bills 34 & 54, the Tiburon Police Department does not share data with law enforcement agencies outside of California or federal agencies, and does not share data with any agency - federal, state, or local - for the purpose of immigration enforcement. 

In addition to our own efforts to ensure compliance with our policy, SB 34, and SB 54, the Flock system has two important features for California law enforcement agencies:

  • A filter to prevent out-of-state Flock clients from accessing California law enforcement agencies' data entirely
  • A requirement that users input a 'reason' for their search for auditing purposes
