Solution context
Security-grade access where every entry answers for itself
Ministries, agencies, and sensitive facilities can’t treat access as best-effort. Duall Master combines least-privilege access, governed visitors, reviewable video, and staff attendance on one platform — with an immutable audit trail and on-premise deployment under your control.
One command surface
Module-by-module rollout
Audit-friendly operations
Where trust is the requirement Where trust is the requirement
Restricted areas, full chain of custody
Clinical wards, records rooms, and government facilities can’t treat access as best-effort. Duall Master enforces who reaches each area, keeps an immutable record, and lets investigators rebuild any incident under role-based control.
- 1
Least privilege by zone
Staff and contractors reach only the clinical or restricted areas their role allows — every decision recorded against policy.
- 2
Visitors with host accountability
Visitors and contractors arrive against approved invites, tied to a named host — no anonymous entry.
- 3
Evidence that holds up
Camera, access, and intercom events resolve to one RBAC-gated incident timeline on an immutable, multi-year audit log.
A day in this building
Operations unfold as one connected timeline.
The value is not only individual modules. It is the way everyday movement, approvals, exceptions, and review become one operating picture.
- 01
Cleared entry
Staff and contractors badge into controlled areas against role and clearance; every decision is recorded.
- 02
Governed visitors
Visitors and contractors arrive against approved invites, tied to a named host — no anonymous entry.
- 03
Incident reconstruction
Access, visitor, and camera events resolve to one RBAC-gated timeline for review.
- 04
Immutable record
Every change and auth event lands in an immutable, multi-year audit log — on-premise if required.
Before and after
Strictly controlled areas where only cleared roles may enter
Evidence, audit, and incident-review requirements that have to hold up to scrutiny
Deployment policy that often mandates on-premise or air-gapped operation
Integrations and AI assistance that must stay governed and reviewable
Shared identity, policy, and site structure
Live events with module context attached
Governed operator actions with audit history
Phased expansion without replatforming

Module combinations for this environment
Each context starts with the module that solves the clearest operational pain, then expands on the same foundation.
Access Control
A shared platform for access decisions, credentials, audit, and operator response across sites and module combinations.
Explore module →Visitor Management
Pre-registration, QR passes, watchlist screening, and host notifications run on the same identity, access, and audit backbone as the rest of your site.
Explore module →Video Management (VMS)
Standalone CCTV makes you scrub hours of timeline. Here, every event points at the right camera and the right second — and every clip you export is evidence.
Explore module →Attendance
Because it reuses the same identity, doors, and schedules as access control, attendance needs no extra hardware and no double data entry.

Access Control + Visitor Management + Parking · 2025
Ministry of National Defense
When one of Vietnam’s most security-critical institutions needed access control at national scale, it chose Duall Master — deployed across 15 military service branches under Project 06 (Đề án 06), unifying people, vehicles, and visitors on a single platform. Personnel are recognized by face, fingerprint, or card; vehicles by licence plate; visitors by chip-embedded citizen ID — every entry tied to a verified identity.
Access Control + Time Attendance · 2019
Ministry of Information and Communications
The Ministry of Information and Communications has run access control and staff attendance on Duall Master at its Vietnam headquarters since 2019 — 12 doors secured with QR and Face ID, where the same recognized entry also records attendance.
Scenario operating model
Government & security-sensitive needs connected site signals, not another point solution.
Modules in play
- 01
Signal
Doors, visitors, cameras, intercoms, and parking generate live signals — not isolated alerts.
- 02
Context
Identity, policy, site, zone, and related module records attach to every signal.
- 03
Action
Operators approve, deny, review, or escalate inside one governed workspace.
- 04
Audit
Every decision keeps the who, what, when, and evidence — ready for review.
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
- 01
Begin with least-privilege access and a complete audit trail
- 02
Add governed visitor and contractor entry with host accountability
- 03
Connect video evidence and integrations under role-based control
Proof path
Evaluate the real workflows before expanding scope.
