Flock & ALPR cameras in Arizona

Arizona records 2,857 mapped plate readers across 102 operators. Tucson Police Department runs the largest share at 8%, ahead of Chandler Police Department on 109. Every count on this page is measured inside the state line, so it's a floor for the state — not an estimate stitched together from overlapping city boxes. 592 of the 2,857 cameras carry no operator at all, so the operator shares above are shares of the attributed cameras.

Phoenix and Tucson have full pages with operator, vendor and direction breakdowns; the other metros are covered by the live map. These are bounding-box reads around each city, useful for comparing metros but not for adding together — boxes overlap and spill across state lines. The headline figure is counted inside the border and is the honest state total.

The top of the Arizona table is Tucson Police Department at 234. What matters for anyone reading the map is how long the tail is — 102 operators in total, so most cameras belong to agencies that individually run only a handful. Private businesses appear too: of the cameras with a recorded operator type, 36 are privately operated.

Where the map has no operator tag, the operator is inferred from the surrounding jurisdiction; that applies to 1,861 of 2,857 cameras in Arizona. Treat names as likely, not certain.

'Flock camera' is shorthand here, not the whole story: 87% of vendor-tagged cameras in Arizona are Flock Safety, and Motorola Solutions accounts for 216. 114 cameras are unattributed to any vendor.

The map knows which way 87% of Arizona's cameras face (2,492 of 2,857). Mounts, where recorded: pole (365), street lamp (99), wall (6), ceiling (2).
