Public map data records 1,237 ALPR cameras inside Massachusetts's borders as of 3 September 2026, run by 115 different operators. Cambridge leads the state's metros with 717. See every camera, which way it faces and its approximate capture zone — free, no account.
Massachusetts records 1,237 mapped plate readers across 115 operators. Worcester County Sheriff's Office runs the largest share at 4%, ahead of Norfolk County Sheriff's Office on 52. 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. 227 of the 1,237 cameras carry no operator at all, so the operator shares above are shares of the attributed cameras.
Open the live camera mapHow the 1,237 in-state cameras cluster: counts around each major MA city as of 3 September 2026.
Boston has a full page 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 Massachusetts table is Worcester County Sheriff's Office at 54. What matters for anyone reading the map is how long the tail is — 115 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, 20 are privately operated.
Names are drawn from OpenStreetMap tags, falling back to the jurisdiction the camera sits in (651 of 1,237 here). A camera's operator is not always the body that paid for it.

Records-based sources document 58 agencies running plate readers in Massachusetts, against 115 operators visible on the map. Where the Atlas has a documented program and the map has few cameras, the cameras are likely there and simply not yet mapped.

Public map data records 1,237 ALPR cameras inside Massachusetts as of 3 September 2026, counted against the state boundary rather than by metro box. 1,012 of the vendor-tagged ones are Flock Safety. Treat it as a floor: cameras appear as people map them, and rural areas are thinly covered.
The largest clusters are around Cambridge (717), Boston (693), Lowell (502), Springfield (279), Worcester (192). Smaller MA towns appear on the live map too — these are simply the biggest metro areas.
115 operators in total. The largest is Worcester County Sheriff's Office with 54 mapped cameras, then Norfolk County Sheriff's Office with 52. Of cameras with a recorded operator type, 362 are police, 289 are sheriff's offices and 20 are privately run.
No. Flock Safety is tagged on 1,012 of 1,088 vendor-recorded cameras (93%); Motorola Solutions accounts for 25, and 147 cameras have no vendor recorded at all. 'Flock camera' is the common name, but the map covers every ALPR it can find.
BanditKin's navigation offers opt-in, field-of-view-aware camera avoidance with a strength slider, using the 1,103 Massachusetts cameras that have a recorded facing direction. If no camera-free route exists it says so and falls back to the normal route. Preferring not to be logged by a commercial surveillance network is a privacy preference — the app uses public camera-location data.
