Overview
The Sun Prairie Police Department uses Flock Safety's Automated License Plate Reader (ALPR) system to help solve and reduce crime in our community. ALPR cameras capture images of license plates and compare them to databases, such as "hotlists" of vehicles associated with crimes or missing persons. This technology allows officers to quickly identify vehicles of interest. The system also allows officers to search past images of vehicles when investigating a crime. To protect privacy, the system is not used for traffic enforcement, personal data collection, or surveillance based on race or other characteristics.
