Security & Privacy

Built for trust and compliance

DHI's architecture is designed to meet the security and privacy requirements of unions, regulators, and enterprise security teams.

Trust Signals

Concrete answers, not abstract reassurance.

Privacy, legal, and operations teams can assess data movement, retention, encryption, and review paths up front, before the first call.

Privacy posture

On-prem by default

DHI spells out exactly what leaves the premises and what never does, so privacy reviews can start immediately.

Data movement

Structured events only

Operators can review the event payload, retention posture, and clip-governance model before any live security meeting.

Encryption

TLS 1.3 + AES-256

Every event and clip is protected in transit and at rest, not left to vague trust language.

Stakeholder path

Security architecture review

Your security team can move straight into an architecture review without sitting through a generic demo.

Compliance signal

Audit-ready controls

Audit-ready controls and a sample event payload give legal, OT, and privacy teams concrete material to inspect.

Privacy by design

DHI's edge-native architecture ensures that sensitive video data stays under your control

On-premises video retention

Raw video never leaves your premises by default. All inference happens at the edge, ensuring complete control over sensitive footage.

Privacy firewall

Only structured events and policy-approved clips are transmitted off-site. Configurable policies ensure compliance with internal and regulatory requirements.

End-to-end encryption

All data in transit uses TLS 1.3. Data at rest is encrypted using AES-256. Key management follows industry best practices.

Role-based access control

Granular permissions for viewing events, accessing clips, and configuring patterns. Full audit trails for all access and configuration changes.

Audit and compliance

Complete audit logs for all system access, configuration changes, and data exports. Designed to support FIPS and FedRAMP requirements.

Data governance

Configurable retention policies for events and clips. Automated data lifecycle management and secure deletion capabilities.

What leaves your premises

DHI's privacy firewall ensures only approved data is transmitted

Transmitted

Structured safety events (timestamps, locations, pattern types)
Policy-approved video clips (configurable duration and retention)
Aggregated analytics and metrics (no PII)
System health and performance telemetry

Stays on-premises

Raw camera feeds and full-resolution video
Personally identifiable information (PII)
Biometric data and facial recognition
Historical video archives (unless explicitly exported)

Secure Metadata Workflow

JSON Payload v4.2

DHI generates structured metadata events at the edge. Below is a sample operative payload showing how person-down alerts are formatted before being pushed to your VMS Alarm stack.

{
  "event_id": "evt_9x2kL01",
  "timestamp": "2026-03-30T10:14:22.451Z",
  "pattern": "PERSON_DOWN",
  "confidence": 0.984,
  "location": "Platform 4 - South Wing",
  "edge_node_id": "node_772",
  "metadata": {
    "latency_ms": 150,
    "vms_alarm_triggered": true,
    "privacy_masked": true
  }
}
