Use case
When seconds matter, lock down and account for everyone from one screen
In an emergency, fragmented systems cost time. Duall Master lets operators trigger lockdown across doors and zones, see who is still inside with live muster, and hand responders a single timeline of access, video, and intercom events.
One command surface
Module-by-module rollout
Audit-friendly operations
How it plays out
The scenario, step by step on one timeline.
Each step ties to a real platform action — not a slideshow.
Trigger
An operator initiates lockdown across the affected doors and zones from one screen.
Before and after
Before Duall Master
Lockdown that depends on running door to door
No live, reliable count of who is inside which zone
Access, video, and intercom in separate tools during a crisis
After-action review stitched together from disconnected logs
After Duall Master
Shared identity, policy, and site structure
Live events with module context attached
Governed operator actions with audit history
Phased expansion without replatforming
Most relevant modules
Module combinations for this use case
This use case starts with the module that solves the clearest operational pain, then expands on the same foundation.
Module stack
One operating picture, assembled module by module.
Shared foundation
Live operations layer
Access, visitors, parking, video, intercom, and audit events resolve into the same command surface.

Scenario operating model
Emergency response & lockdown needs connected site signals, not another point solution.
Tap any layer to see how it helps a buyer evaluate the platform.
Signal
Doors, visitors, cameras, intercoms, parking, and devices generate live operational signals instead of isolated alerts.
01Signal
Doors, visitors, cameras, intercoms, parking, and devices generate live operational signals instead of isolated alerts.
02Context
Each signal becomes useful because operator, person, role, site, zone, policy, and related module records are shown together.
03Action
Teams approve, deny, review, escalate, annotate, or link evidence without leaving the command surface.
04Audit
Every decision keeps the who, what, when, why, and related evidence needed for handoff, reporting, and investigation.
Buyer-facing model for phased adoption: start with the clearest pain, then add adjacent modules on the same foundation.
Deployment and trust
Typical adoption path
- 01Map zones, doors, and lockdown groups
- 02Define muster points and operator response actions
- 03Rehearse with drills, then review the timeline afterward
