Where Wisconsin gets Flocked

This map stays in Wisconsin. It shows publicly mapped ALPR cameras, all 261 drivable land exits, and modeled road coverage around Wisconsin communities. Red means the road graph found no unwatched driveable exit. Violet means every major highway entrance and exit is covered, though smaller roads remain.

Important: Flock cameras do not automatically draw these colored boundaries. In Flock's search product, an authorized user draws a polygon or bounding area on an ESRI map to select which cameras a query will search. Flock confirmed that workflow in its Michigan state contract, requirements 80 and 110. Here, “camera-made geofence” is a plain-language label for a modeled vehicle-coverage zone: can a driver leave a Wisconsin place on the mapped road network without passing a known ALPR? A camera outside a municipal line can still close a practical route. The fill follows the legal boundary for readability; it is not a Flock-generated polygon and does not prove ownership, access, retention, or sharing.

What “all major entrances and exits covered” means

Major corridor = any road crossing the boundary that OpenStreetMap classes as motorway, trunk, primary or secondary, plus their ramps. In Wisconsin terms: Interstates, US highways, State highways and County Trunk highways — the roads an ordinary driver actually uses to enter or leave a place. Residential streets, town roads, farm lanes and driveways are excluded from this test.

Covered = a mapped ALPR sits within 800 m (0.5 mi) of the point where that corridor crosses the line, or anywhere along that same corridor inside the boundary. Either way you cannot drive that corridor in or out without being read. Divided highways are counted once per crossing.

Corridor-sealed (violet) = at least two major corridors cross the line and every one of them is covered, while the place is not fully sealed — unwatched minor roads still exist. You can still get out. You cannot get out on a highway. That is a weaker claim than sealed (red), which requires that no drivable road of any class offers an unwatched route, and a much stronger one than a partial ring.

Can you leave Wisconsin without being logged?

Every one of Wisconsin's 261 mapped drivable land exits is scored against the camera index on both sides of the state line.

Green — no mapped ALPR within 0.5 mi on either side.
Red — the state you are leaving logs you on the way out.
Amber — your state does not watch this crossing, but the next one reads you the moment you arrive.

Large rings are Interstate, US, State and County Trunk crossings; small ones are town and residential roads. Green means no camera is mapped there — DeFlock is crowd-sourced, so it is evidence of an absence in the data, not proof of an absence on the road.

The Wisconsin road-network test

A dot shows a mapped camera. A colored place shows the result of a road-network coverage model. The strongest claim is narrow: given the roads and cameras in this snapshot, the model found no unwatched drivable exit. It is not a claim that Flock itself created that polygon.

Ways out of Wisconsin — both sides of the line

Red = the state you are leaving reads your plate. Amber = it does not, but the next state reads you arriving. Both = logged twice. Green = no mapped ALPR within half a mile on either side (Wisconsin’s complete 261-exit set; other states show watched crossings). Large markers are Interstates, US, State and County Trunk routes.

Crowd-sourced from DeFlock / OSM. An unmapped camera is invisible here — green is absence in the data, not a promise. Distances use a liberal 0.5-mile radius.

Cameras: DeFlock / OpenStreetMap surveillance:type=ALPR, queried live through keyless Overpass endpoints. Roads and boundaries: OSM. Major entrance / exit = a boundary crossing on an OSM motorway, trunk, primary or secondary road — Interstate, US, State and County Trunk routes — counted once per crossing and treated as covered when a camera sits within 800 m of it or anywhere along that corridor inside the line. Colored areas are modeled coverage zones, not geofences supplied by Flock. This is not proof of agency intent, access, retention, or data sharing. Analysis runs in this browser — nothing is uploaded and no API key is required.
