Why it matters
A corner that leaks every few weeks and a machine that overheats every summer are patterns, not a series of unrelated incidents. Storing localisations rather than only alarms is what lets a site notice the difference.
Systems & architecture
Hazard footprint
A hazard footprint is a stored record of one completed localisation - the bearing, the peak magnitude, the estimated source coordinate and the full angular sweep profile - retained so that recurring hotspots at a site can be learned over time.
How it works
Each footprint is persisted independently of the incident it came from, so the accumulation survives incident closure and builds into site-level knowledge across successive investigations.
Example
Three footprints over a month, all bearing on the same sector of a store, identify a location worth inspecting rather than three separate events worth closing.

- Source bearingA source bearing is the compass heading, relative to a sensing node's fixed installation position, of the sector that recorded the strongest response during a rotational sweep.
- Digital hazard twinA digital hazard twin is a three-dimensional model of a monitored facility, registered with node positions and a named asset register, onto which a measured hazard source and its forecast spread zones are projected.
