The portal listed a retention period of 365 days, after which plate reads are deleted. Retention is the number that decides how much of your ordinary driving is searchable at any moment — a 30-day window means a month of your movements, not just the day you were near a camera.
The portal reported 1,020 searches of that data in the 30 days before it was captured, against 441,800 vehicle detections over the same period.
166 outside organizations had access to this agency’s plate data when the portal was captured. Sharing is the part of ALPR that surprises people most: a read collected on your street is searchable by departments you have never heard of and never voted for.
A blank field means the portal did not publish that number, not that it was zero. Figures can have changed since 2024; the live portal is the current source.

Where these figures come from
Flock Safety publishes a transparency portal for each customer agency. The portal figures above were captured by The News & Observer / McClatchy (private_eyes) between July 2023 and April 2024 and are shown unchanged. Where the live portal differs, the portal is right. The mapped count comes from FlockDetour’s own public camera data, counted October 5, 2026.
