ALPR / Flock
Crystal Lake Police publicly documents its use of fixed automated license-plate readers, states that non-investigative plate data is automatically deleted after 30 days, and says the system does not use facial recognition. The City’s 2026 budget also says additional Flock cameras are being added to the department account with grant support.
ALPR policy / sharing
Crystal Lake publishes an ALPR policy requiring a related report or event number for investigative searches, logging access, documenting outside-agency requests, and limiting access to authorized law-enforcement purposes.
PUBLIC RECORDS · FOIA
Primary government records are preferred. Where practical, NoRec keeps a local archival copy alongside the official source so citations remain auditable if a government URL later changes.
