OpenStreetMap / DeFlock contributors — US ALPR camera nodes (man_made=surveillance, surveillance:type=ALPR)
https://deflock.me/
retrieved 2026-08-17
Method
count(tags.manufacturer == 'Flock Safety') / len(elements) * 100, over all nodes (not just manufacturer-tagged ones)
from: data/alpr-us.json
Caveats
- Underlying camera locations are volunteer-crowdsourced (DeFlock/OSM), not verified by any camera operator or government body -- likely incomplete, possibly outdated or inaccurate (see repo TERMS.md).
- README (2026-08-17 extract) states '82.3% Flock Safety by manufacturer' -- recomputed directly from data/alpr-us.json this is 78.91% of all 131735 nodes, or 85.67% of the 121333 nodes that carry a manufacturer tag. Neither denominator reproduces the README's 82.3%; treat the README figure as unverified and this recomputed value as authoritative.
