01
Push to talk
Role- and channel-based voice communication with a clear speaking state.
GuardLink security communication
The radio network on every approved device.
Push-to-talk, duress alerts, incident reporting, and control-room visibility for hospital security teams across desktop, phone, and Android watch workflows.
Connected
Reconnecting
Offline fallback
Operational workflow
Security communication without a separate radio estate.
Designed for short, high-pressure interactions with clear state feedback and an auditable incident trail.
02
Duress alert
Deliberate hold-to-raise SOS action with hospital-team escalation.
03
Incident capture
Structured severity, location, and handover details for the control room.
04
Watch workflow
Large-target SOS and alert views shaped for Android smartwatch screens.
Weak-network handling
The user always knows the connection state.
GuardLink separates live radio availability from locally available safety actions. Reconnection is visible, failed sends are surfaced, and queued actions can retry when the network returns. Final readiness still requires device and hospital-network testing.
CONNECTED
Radio and alerts available
Normal PTT operation with live channel and presence updates.
RECONNECTING
Automatic recovery in progress
The interface keeps controls stable while connection recovery is attempted.
OFFLINE
Radio unavailable, fallback shown
The app makes the failure explicit and preserves retryable safety actions where supported.
