A pre-identified list of vehicle license plates associated with a specific law enforcement interest that, when detected by an ALPR system, generates an alert for officer awareness and potential enforcement action. A hotlist alert alone does not establish probable cause and must be independently verified by an officer before enforcement action.

Pursuant to California law, the West Sacramento Police Department (WSPD) only shares ALPR data with California law enforcement agencies that utilize Flock, Vigilant, Axon, or a similar ALPR platform, and that have formally requested and been granted access in accordance with applicable law and Department policy.

WSPD does not share ALPR data with agencies outside the State of California or with any federal agencies. All data sharing is governed by state law, Department policy, and user agreements that require compliance with privacy, data security, and audit requirements.

In addition to other California agencies sharing their data with us, it is permissible for out-of-state agencies to share ALPR data with California agencies when the data is used for legitimate law enforcement purposes and handled in compliance with applicable laws, policies, and privacy protections.  Strict access controls and data sharing agreements are in place to ensure that ALPR data is only shared between approved partner agencies on a mutually exclusive basis, preventing unauthorized access or dissemination to out-of-state entities.

All ALPR data downloaded to the server should be stored for a minimum of one year and in accordance with the established records retention schedule. Thereafter, ALPR data should be purged unless it has become, or it is reasonable to believe it will become, evidence in a criminal or civil action or is subject to a discovery request or other lawful action to produce records. In those circumstances the applicable data should be downloaded from the server onto portable media and booked into evidence.
