Vehicle Gate — two-unit live tracking

Units spaced along a road turn every passing vehicle into a timestamped event with direction, speed, and size — the airport ground-vehicle chokepoint, running on a real street.

Every unit must be joined to the same network as this device (a unit's own hotspot only serves one client). Fastest path: search this network below — it finds every unit by its hardware serial and slots them in order, no typing, and adds a new slot for each extra unit it finds. A unit with a real GPS fix places itself on the map. Rather type them in? Use the manual fields underneath.

Or enter addresses manually

Site name (optional)Names this site's vehicle history, so it survives a unit swap. Renaming starts a new history; blank keys it by the units' serials and typed pins.Lane standoff, m (optional, measured)Units to the lane centre. Vehicle size scales with its cube (±30 % moves an estimate ~2×); blank uses a 6 m guess and halves the class confidence.

Detection threshold8 nTSample rate2 Hz poll

How fast the app reads each unit. Speed resolves only as finely as the slower of this and the unit's publish rate.

No addresses needed — find every unit on this network, however many there are. Each is identified by its hardware serial, so slots stick even when their IPs change.Scanning needs the iOS app or a local dev server — a deployed HTTPS page can't probe http:// LAN addresses.

No units needed — a simulated taxiway for the demo. Every surface shows amber “Simulated.”

Enter at least one unit address to start watching.
