Mapped to a shared offline runtime family and usable with a recording or compatible ESP32 CSI stream.
Intended capability
Evaluate the sensing evidence for “Trailer Heartbeat — Stowaway & Intrusion Sensing” in a stationary, controlled, ground-truthed vehicle study. This is not a vehicle, occupant, child, pet, or driver-safety system.
This describes the intended outcome. Readiness is shared-family mapped, evidence is class B, and a catalog mapping or recording is not proof of this outcome at a real site.
Solution blueprint
See the environment before installing it.
This exact kit is one of 191 first-class designs. It includes geometry, objects, nodes, wording, scenarios, installation, limitations, and catalog-bound readiness.

Bundled recording
A related Automotive scene
This is one recorded vertical scenario. It is not separate validation of every capability in the catalog.
01 The physics
RF penetrates cargo stacks and thin walls; a concealed human adds a breathing-band micro-Doppler signature and perturbs multipath amplitudes even when motionless. Door breach and human entry create large transient Doppler plus a step change in CIR path structure.
02 Shared processing path
Micro-Doppler 0.1-0.5Hz breathing detector + CIR sparse-recovery step-change detector -> MVE anomaly vs sealed-trailer baseline -> RTI differential for rough position inside the box.
This is a capability design path. Components may be shared with other catalog entries; it is not presented as a unique algorithm.
03 Validation plan
Presence and through-wall detection are class-A on ESP32-wall (LOS/NLOS AUC 0.69) and OPERAnet; own experiment: loaded 40ft trailer, person concealed behind pallets at 3 depths, day-long empty-trailer false-alarm run.
04 Commercial hypothesis
Anti-stowaway and cargo-intrusion certification for cross-border fleets — one $100 mesh per trailer, sold to fleet security directors and customs-compliance officers facing clandestine-entrant fines.
