| Object | Moment | Range (SNR 5) |
|---|---|---|
| pocket metal | 0.02 A·m² | 0.5 m |
| handgun | 0.2 A·m² | 1.1 m |
| rifle | 1 A·m² | 1.9 m |
| bicycle | 3 A·m² | 2.8 m |
| motorcycle | 30 A·m² | 6.1 m |
| passenger car | 200 A·m² | 11.4 m |
| pickup / SUV | 600 A·m² | 16.4 m |
| truck | 1,500 A·m² | 22.3 m |
| heavy truck / armoured | 5,000 A·m² | 33.3 m |
Personnel are only detectable within about 2 m of a unit: this is a vehicle sensor at fence range.
For car-class localization keep units ≤ 20 m apart; at 30 m only truck-class targets pair.
Floor used: 2.7 nT. Ranges are order-of-magnitude broadside estimates (a factor of ~2–3 either way) — see lib/perimeter/physics.ts.
off (dry-run)
Sends to the webhook/email/SMS/Slack destinations configured on the server (PERIMETER_ALARM_WEBHOOKS / _EMAILS / _SMS / _SLACK). While off, the test button previews a dry run only — nothing leaves the server.
Every numeric card in Demo carries the simulated tag above. The green Live badge appears only once at least two real units on the line are reporting — one unit, or none, never fabricates a track, a chainage or a moment. Amber marks simulated data and large-vehicle emphasis only, never a live unit's own identity. This is a vehicle sensor at fence range: it does not detect personnel, or what they carry, beyond a couple of metres.
