Sugar Grove public safety official describes limits and benefits of automated license‑plate reader network

A village public safety official explained to the Board of Trustees how Sugar Grove’s automated license plate reader (ALPR) system operates, how data is stored, and what controls exist on interstate access to that data.

The official said ALPR vendors store plate reads in the cloud for a defined retention period and that municipalities typically control access. "Illinois is very specific. It can't be shared outside of Illinois for the purposes of immigration checks ... or for women's rights for health care," the official said, explaining statutory limits that the vendor enforces via written agreements.

The speaker described a nationwide search product offered by the vendor Flock that, when enabled, allows reciprocal access between participating agencies. He said reciprocal access can aid investigations — for example, locating stolen vehicles or tracking vehicles that cross state lines — but stressed that Illinois law and vendor policy prohibit use for immigration enforcement or reproductive‑health investigations.

The official cited a prior instance in which an out‑of‑state agency used ALPR data to locate a missing person; no charges resulted. The speaker also said the vendor has revoked access for some agencies that violated use restrictions.

Village staff said they require written agreements with out‑of‑state agencies seeking access and that searches should be tied to a legitimate law enforcement purpose with a report number. Trustees asked for transparency materials and a copy of vendor policies for public review; staff indicated they would share information available from the vendor’s website and internal policy.

No formal change to Sugar Grove’s ALPR policy or interagency access agreements appears in the provided transcript excerpt.
