Check the records.
Stop Flock maps reported ALPR cameras, tracks public-record requests, and documents contracts, permits, data practices, and government accountability across Tennessee.
Why this exists
Public roads should not mean invisible public records.
Automated license plate reader systems can record vehicle plates, time, location, vehicle characteristics, and other metadata. Stop Flock focuses on the public records behind those systems: who operates them, where they are installed, what contracts govern them, how long data is retained, and who can access it.
This project does not publish captured plate data or individual travel histories. The focus is infrastructure, policy, contracts, permits, oversight, and government accountability.
What we track
Contracts
Vendor agreements, renewals, grant funding, invoices, amendments, and procurement records.
Data Practices
Retention, deletion, sharing, outside-agency access, audits, and vendor access.
Permits
TDOT applications, licenses, location exhibits, roadside reviews, and state ROW authorization.
News & findings
Track what the records actually show.
Stop Flock will publish short, source-based updates as records arrive: camera counts, contracts, TDOT permits, data-sharing terms, procurement records, and agency responses.

Ongoing researchTennessee project
Starting in Hamilton County.
Our initial records work is focused on Chattanooga, Collegedale, Hamilton County, and ALPR installations located on Tennessee Department of Transportation right-of-way.
The goal is to build a verifiable public inventory from official records, not assumptions: camera by camera, contract by contract, and permit by permit.
Camera map
Hamilton County ALPR camera map
The red camera points are loaded from the DeFlock/OpenStreetMap community dataset so the map can be useful now, without waiting for every agency records request to be completed.
DeFlock locations are community-sourced and should be treated as reported / unverified until confirmed by an official record, field observation, or other reliable documentation. Stop Flock will add verification status as records arrive.
DeFlock / OpenStreetMap community report
Stop Flock observed / photo documented
Data note: DeFlock camera locations are crowdsourced from OpenStreetMap and update independently of Stop Flock.
A pin on this map does not by itself establish camera ownership, permit status, operational status, or legal compliance.
Do not trespass, stop in unsafe locations, or interfere with equipment to verify a camera.

Community tips
See one? Put it on the map.
If you see a roadside ALPR camera, send the location and a photo if you can safely obtain one. Community tips help us verify and improve the public map. Do not stop in traffic, enter restricted property, or interfere with equipment.

Important
Stop Flock is an informational and public-record transparency project. It does not provide legal advice, does not encourage tampering with public or private equipment, and does not publish confidential captured plate data or individual travel histories.
