Automatic License Plate Readers (ALPR)
on March 17, 2022 the City Council extended the use of ALPR cameras in Town for a year. In 2023, the cameras will be reviewed again.
On April 15, 2021, the Los Altos Hills City Council approved the installation of Automatic License Plate Readers (ALPRs) at fixed locations throughout Town for the purposes of deterring crime and helping to create a safer environment for all those who live, work, or visit the Town.
The ALPRs installed in Town will gather data associated with vehicle license plates that can be shared with the Santa Clara County Sheriff's Office for purposes, including, but not limited to, identifying stolen and wanted vehicles, recovering stolen property, and gathering crime related information.
The picture to the left is an image of how the ALPR cameras will look on Town streets.
ALPR cameras benefit the Town in three ways:
- The physical presence of a camera and accompanying street signs indicating recording is in process can limit crime occurring in the first place;
- After a crime has occurred, the data which has been recorded can give law enforcement leads for investigations; and
- The cameras have the ability to send instant notifications to law enforcement when a vehicle of interest has been identified.
About The System
The Town has partnered with the ALPR camera vendor, Flock Safety, to install 40 ALPR cameras throughout Town. Every street entrance into Town will have a camera scanning the license plates of inbound traffic to Los Altos Hills. Several other major intersections and roadways within Town boundaries will also have cameras installed. License plate information will be compared against law enforcement lists of license plates associated with stolen vehicles and people that have committed a crime. If the ALPR system detects any matches, the Santa Clara County Office of the Sheriff will be notified immediately to investigate.
See map below for camera locations. Please note that exact camera locations are subject to change as the implementation process is underway.
The Opt-Out List
Los Altos Hills residents may opt-out their vehicle's license plate from the Flock ALPR system if desired. Residents must submit proof of vehicle registration to an incorporated Los Altos Hills address to be eligible for the opt-out program. Opting out of the ALPR system stops vehicles from being tracked by the Town's ALPR system. The opt-out list is voluntary for Town residents.
**Please note that that the opt out list applies to license plates, not vehicles. If an opted out license plate is transferred to a different vehicle, the opt out will automatically apply to the receiving vehicle and the donor vehicle will no longer be opted out (since it will no longer have the opted out license plate).
Town ALPR Policy
State law also requires that agencies with ALPRs to record when and who accesses the ALPR data, terms used in records searches, and the purpose for accessing the data. Public agencies are prohibited from selling ALPR data and data can only be shared with other public agencies
On March 18, 2021, the City Council adopted an ALPR Policy for the Town pursuant to State requirements. Click the link below to read the staff report and watch a recording of the discussion.

Based on Council direction, the ALPR ordinance states that anyone found violating the Town’s ALPR Policy is guilty of a misdemeanor and subject to a fine of one thousand dollars ($1,000).
