A security incident timeline is reliable only when every entry identifies its source, timestamp and level of certainty.
This workflow uses approved post-incident voice notes without merging witness statements, system logs and manager assumptions into one polished narrative.
The five source types
| Source | Example | Rule |
|---|---|---|
| Direct observation | Officer saw rear exit open at 22:14 | Record observer, location and time |
| Witness report | Delivery driver reports tailgating | Attribute; do not present as verified |
| System evidence | Badge 417 used at 22:12 | Preserve system, timezone and export |
| Physical evidence | Damaged latch and photograph | Link reference and custody |
| Hypothesis | Door may not have latched | Label as unconfirmed |
The GUARD note
- G — Ground: site, exact location, date and time.
- U — Understanding: verified current situation.
- A — Action: immediate control and notification.
- R — Record: CCTV, access logs, photos, witnesses and references.
- D — Direction: owner, escalation and next update.
Response before recording
Protect people, control the incident, call emergency services where required and begin evidence procedures before dictating. Move to a secure private location.
The source-checked timeline
| Time | Event | Source | Confidence | Action |
|---|---|---|---|---|
| 22:12 | Badge 417 used | Access-control export | Verified system record | Preserve log |
| 22:14 | Rear exit observed open | Officer A | Direct observation | Door secured |
| 22:18 | Tailgating reported | Driver statement | Unverified report | Review CCTV |
Do not ask AI to fill missing times or reconcile conflicting accounts automatically.
The incident-to-report process
- Control the incident and protect people.
- Preserve original CCTV, access logs, photos and documents.
- Record a private GUARD note.
- Correct names, locations, times and speaker attribution.
- Build the source-checked timeline.
- Complete the formal control-room and incident records.
- Assign investigation and corrective actions.
- Give the next shift only necessary operational information.
- Apply evidence and retention rules to audio separately.
Operational security
Do not dictate alarm codes, patrol patterns, camera blind spots, master-key arrangements or confidential intelligence into a broadly accessible workspace. Use protected references and restricted systems.
Fair investigation
A debrief should examine equipment, staffing, procedures, supervision and handover quality. AI cannot determine responsibility or credibility.
Worker privacy
A defined briefing or debrief is different from continuous audio surveillance. Use targeted, announced recording and avoid undisclosed monitoring of staff conversation.
