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.

Set up the pair

Both units 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 A/B/C, no typing, and 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

Third unit (optional). Add a third unit on the same line and every pass must chain across all three to be confirmed — the middle-time coincidence rejects the marginal one-baseline ghosts. Order matters: A = west, B = middle, C = east — B is the unit shared by both baselines. Leave the address blank to run as a plain pair.

Wider spacing = better speed accuracy (±4.7 mph at 30 mph with this spacing). 30 m+ recommended.
No addresses needed — find every unit on this network. Each is identified by its hardware serial, so A/B/C 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.”
