The policy describes detection of plates together with vehicle make, model, color, and unique identifiers.
LOCAL SURVEILLANCE · BOONE COUNTY / BELVIDERE, ILLINOIS
Local ALPR systems, documented from the record.
Public records and field observations are presented separately. A mapped or photographed camera is not attributed to an agency unless ownership is established.
The archived camera registry contains 13 records assembled from physical scouting and third-party mapping. Agency ownership is unknown for most entries. Three Flock devices are marked physically confirmed. A separate City of Belvidere FOIA response lists seven city locations at the time of that record: six installed and one in planning.
DOCUMENTED · BCSO POLICY 450
What the Boone County Sheriff's Office policy says.
The policy states reasonable suspicion or probable cause is not required before using an ALPR system itself during authorized operations; enforcement still requires an independent lawful basis.
Officers are directed to verify alerts and vehicle information rather than treating an ALPR hit alone as sufficient enforcement justification.
The policy states Flock-hosted data is purged after 30 days.
ALPR data downloaded to the county server should be stored no longer than one year, subject to evidence and records-retention requirements.
The Sheriff or designee is to audit ALPR detection-browsing inquiries at least once per calendar year, including a random sample.
The policy describes individual credentials and system use capable of being fully audited.
The policy states data will not be shared by the county or its contractors/subcontractors for federal immigration-enforcement purposes involving specified federal immigration agencies.

FIELD / MAP REGISTRY
13 working camera records, with ownership mostly unresolved.
The original registry contains a mix of Flock Safety, Motorola Solutions, and one unknown-vendor entry. Agency ownership is marked unknown across the working registry. That uncertainty is preserved here instead of being inferred from geography.

Original camera registrySUPPORTED / NOT SUPPORTED
What the records support — and what they do not.
- The BCSO policy describes capture of more than the plate itself.
- The policy permits ALPR use without requiring reasonable suspicion or probable cause merely to operate/query the system in the authorized context described.
- Alert verification is required before enforcement action.
- Flock-hosted retention is described as 30 days.
- County-side downloaded data can remain up to one year under the policy, with exceptions for evidence/retention obligations.
- Annual browsing audits are required by policy.
- That ICE has direct access for immigration enforcement; the supplied policy says the opposite for that purpose.
- That an officer may lawfully stop a vehicle solely because an ALPR alert occurred; the policy requires verification and a lawful basis.
- Which agencies currently receive Boone County ALPR data.
- How many users currently have system access.
- What the annual audits actually found.
- The ownership of most devices in the working camera registry.
UNRESOLVED
Not established by the published records.
- Results of annual audits and any corrective actions.
- Current sharing and authorized-agency lists.
- Detection-browsing usage totals and access-log details.
- Authorized-user counts and training records.
- County retention schedules governing exported ALPR records.
- Current contracts, pricing, renewals, and grants.
