A mobile duress app, a live control-centre dashboard, and a silent SMS trigger — built for the moments where delay is the only thing that can go wrong.

They almost didn't go ahead
Before engaging us, SPG leadership had three honest concerns:
- "Our clients are used to human escalation. Will they trust an app to call for help on their behalf?"
- "What happens when the app is the single point of failure — and the single point of failure is in someone's pocket at 30,000 feet or in a basement carpark?"
- "If we build this and it fails in a real emergency, it ends our business. Not our project — our business."
These weren't hypothetical. These were the objections that almost killed the project in the first meeting.
The hardest problem: a false alarm is as dangerous as a missed one
In security tech, two failure modes destroy trust equally. Miss a real duress and someone gets hurt. Fire a false alarm and dispatch a response team to a client who's fine — the client never trusts the button again.
We built SPG's trigger logic around a confidence signal, not a binary. Accelerometer data, location, network state, and trigger pattern all feed into an alert severity score before the control room sees it. Operators see context, not just "alert." False-positive dispatches dropped to near zero in the first six months.
Built around the customer, not the software
EB Pearls created a full emergency response ecosystem, combining mobile apps, central dashboards, and integration with third-party services.
Mobile Duress/Emergency App
Allowed clients to trigger help instantly from their mobile device, sending real-time alerts to the control centre without relying on manual calls.
Real-Time Video and Audio Streaming
Background Location Tracking
Silent Emergency Trigger via SMS/Call
Control Centre Dashboard
Integration with Third-Party Emergency Services
Connected the platform to external services, enabling seamless escalation when situations required additional support.
Three decisions that made SPG trust the system
SPG had to decide whether to trust technology to handle real-time emergency response or continue relying on manual, fragmented systems.
They opted to implement EB Pearls’ integrated system, including silent emergency triggers and real-time dashboards, despite initial doubts about reliability under real-world pressure.
We built the silent SMS trigger before we built the app.
The client's biggest fear was "what if someone's phone is out, or they can't open an app while being held?" We solved that first — a pre-registered SMS from a specific number auto-triggers the alert. The app came second.
We ran the first live test without telling the guards.
SPG's operations director triggered a test duress at 11pm on a Tuesday. We measured how long it took each guard on shift to respond. That data shaped the dashboard more than any workshop did.
We shipped offline-first, not cloud-first.
In a real emergency, cellular service is the first thing to go. The app queues alerts locally and syncs the moment any connection is available — LTE, Wi-Fi, or satellite fallback via the device's carrier.
Technology stopped being a risk; it became a reliable emergency response network.
“In an emergency, every second matters—but our systems weren’t connected.”
“Our clients now have instant access to help—no matter the situation.”
SPG now operates with a fully integrated emergency response ecosystem. Guards and control centres receive instant alerts, live audio/video feeds, and location tracking, allowing faster, more informed decision-making. Manual coordination has been replaced with automated triggers, and high-profile clients benefit from unprecedented visibility and security assurance.
SPG plans to expand the platform with predictive analytics for threat detection, leveraging the ecosystem to anticipate incidents before they occur.
Built for the industry that can't afford a breach
- End-to-end encryption on all alert, audio, and video payloads
- ISO 27001 aligned data handling (EB Pearls holds current certification)
- Role-based access: operators see only the clients assigned to them
- Audit log of every alert, escalation, and dispatch — immutable, exportable for incident review
- Data residency: Australian AWS regions, no cross-border transfer of client location data
