len(zero_fips) -- counties in county-counts-v2.json's population universe with a camera count of 0

from: data/zero-camera-counties.json

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(DeFlock/OSM), not verified by any camera operator or government body -- likely incomplete, possibly outdated or inaccurate (see repo TERMS.md).
A county with zero mapped cameras is evidence of an unmapped county, not evidence of camera absence, unless corroborated by an independent source (see README 'Methodology note on absence claims').
