Operational summary
Prysma Sentinel is a field-operations platform built for mission-critical work: fleet visibility on a tactical map, contextual SOS alerts, geofences with per-zone rules, persistent per-unit chat, and unified history.
Version 2 ties the physical ecosystem (LoRa nodes and gateway) to the SaaS control plane and the Sentinel mobile app—one source of truth for admins and operators.
Deep dive
Mission-critical field operations—private security, heavy logistics, energy, mining, civil defense, rescue teams—share a common problem: they need to know where their units are at every moment, get alerts when something deviates from plan, and keep a reliable history for audit. Most teams cobble together that visibility from WhatsApp, spreadsheets, radios, and a generic GPS. It works until it doesn't: when a real SOS hits, that improvisation does not scale.
Sentinel solves that with a single control plane wired to dedicated hardware (LoRa nodes with GPS and battery) and a mobile app for field operators. The operations center sees the entire fleet on a tactical map, receives SOS and geofence events in seconds, and keeps a full audit trail. The philosophy is simple: one source of truth, synced across web, mobile, and field devices.
Unlike a traditional GPS, Sentinel is more than dots on a map. Each unit has a chat thread, operational context (last heartbeat, current geofence, active mission), and policies that define how to escalate incidents. Version 2 added assignable missions, data export for external analysis, and an operational dead man switch for lone workers.
The product is built around three roles: the organization administrator, who configures geofences, team, and plans; the field operator, who uses the mobile app to mark duty, view missions, and trigger SOS; and the operations center, which watches the map, responds to alerts, and coordinates the team. Everyone shares live data, with no manual sync steps and no extra browser tabs.
