How our fleet captures proof of a toll crossing
When a car crosses a tolled bridge or tunnel, our device records proof from the road camera at the entry and the exit, and uploads it with a crossing record. Below is a real crossing and how it works.
George Washington Bridge, New Jersey → New York
Approach on the upper level, with the GWB tower ahead.
Passing the New Jersey tower under the large US flag, then onto the span.
Clips are 12 s at 256×144, the landmark clip resolution set over the air.
What every crossing uploads
Each crossing is delivered as 5 files: one crossing record and two 12-second road clips, each with a small sidecar file. The two videos are the billing proof. The sidecars carry time, place and geometry.
| Files | Camera | What it is |
|---|---|---|
1 · .json | — | Crossing record: facility, direction, toll amount, time, GPS, geometry |
2–3 · .mp4 + .json | Road | 12 s around the ENTRY |
4–5 · .mp4 + .json | Road | 12 s around the EXIT |

Two more real crossings, each a zip with the crossing record (including the GPS track of each pass) and both 12-second road clips at 1280×720.
How it works
The device recognises a toll crossing on its own and builds billing-ready proof automatically, with no one searching through footage.
Every toll point is mapped
Each bridge and tunnel is stored with its exact location, road direction and toll amount. The file updates over the air.
The car's position is tracked
GPS positions stream in throughout the trip, each with its own UTC timestamp.
Crossing confirmed automatically
When the car's positions pass through a toll point in the right direction, the crossing is confirmed and the entry and exit clips are saved as proof.
