Integrity you can prove —
at the edge, offline, tamper-evident

Sentinel Systems assures logistics and perimeter integrity where connectivity can't be assumed. Asset-centric Sentinel Crate and area-aware Silent Perimeter Node devices run on one control plane — every event SHA-256 hash-chained and audit-ready.

The offerings

Two device lines. One control plane.

Purpose-built edge hardware for the two problems that share a spine — protecting what moves, and watching what shouldn't.

Asset-centric

Sentinel Crate

An edge module embedded in shipping containers and cases. Detects tamper, shock, light exposure, temperature excursion, and GPS deviation — the moment it happens, wherever it happens.

Offline-first, store-and-forward
SHA-256 hash-chained event log
On-device classification

SPN

Area-aware

Silent Perimeter Node

Distributed sensing nodes for perimeter and area awareness. PIR motion, acoustic, seismic, and magnetic sensing feed a multi-node correlation engine that separates signal from noise.

Coincident-contact correlation

Unifying layer

Common Control Plane

One shared event envelope, policy engine, and idempotent ingest across both product lines. A single operator pane of glass for asset integrity and perimeter posture — with a tamper-evident audit trail.

The platform

Built for the field, provable in the audit

Offline-first

SYS-001

Every device operates and records without connectivity, then reconciles on reconnect.

Hash-chain integrity

SYS-002

SHA-256 chained events make the timeline tamper-evident and audit-ready.

Multi-node correlation

SPN-SYS-004

Coincident contacts across nodes synthesise a single high-confidence intrusion alert.

Field-ready hardware

SYS-003

Low-power edge compute on commodity Raspberry Pi reference builds.

Walk the operator console

The live demo runs on representative data with two guided narratives — an asset-tamper event on a sealed medical container, and a multi-node perimeter intrusion. See the hash-chain audit and correlation engine end to end.
