4 - Incident Timeline Reconstruction Template

A structured method to build a clear, defensible timeline during or after a security incident.

Overview

At the heart of every strong investigation is one thing:

👉 A complete, accurate, time-aligned timeline of events.

A timeline is more than a list of actions - it’s the spine of the incident narrative. It reveals what happened, when it happened, and how each system reacted. It identifies:

• Early warning signs
• Missed cues
• System gaps
• Operator actions
• Behavior patterns
• Root causes

Yet most organizations struggle to reconstruct timelines because their systems operate independently.

This article provides:

• A comprehensive, ready-to-use template
• A step-by-step method for reconstructing timelines
• Common challenges teams face
• Scenarios illustrating good vs. poor timelines
• How BluSKY automates the timeline for you

Why Timeline Reconstruction Is So Hard Today

Most teams rely on manual collection from multiple systems:

1. Different UIs

• Access control software → NVR client → elevator system → alarm panel → analytics dashboard.

2. Different clocks

• Device A may be 13 seconds off.
• Elevator logs might drift by 90 seconds.
• NVR clocks may lag by minutes.

Time drift = investigation risk.

3. Missing evidence

• Video may be overwritten.
• Elevator logs may not export.
• Alarms may not correlate.
• Snapshots may not exist.

4. Manual copy/paste

• Operators often build timelines in Excel, OneNote, or Word.

5. No shared format

• Different operators = different structure.

What a Strong Timeline Looks Like

A strong incident timeline answers:

• What triggered the incident?
• Who or what initiated it?
• How did they move through the building?
• Which devices and systems reacted?
• How long the incident lasted
• Where the security response occurred
• Which decisions were made and when
• What corrective actions were taken

When these components align, leadership gains clarity - and legal, compliance, and insurers gain confidence.

The Official BluBØX Incident Timeline Template

Time	Event Type	Location	Details	Source
4:12 PM	Access Event	Door A - Main Lobby	Denied access; Card ID 8273; mobile off	Access Logs
4:12 PM	Video Snapshot	Lobby Cam 3	Subject approaches turnstiles	Camera Auto-Snapshot
4:13 PM	Elevator Activity	Car 7	Auto-assigned to 14th floor	Elevator Logs
4:14 PM	Alarm Trigger	Zone 3	Glass-break triggered	Alarm Panel
4:14 PM	Video Analytics	Elevator Interior	Object detected on floor	AI Detection
4:15 PM	Response Action	Security Ops	Officer dispatched	Dispatch System
4:17 PM	Operator Note	Command Center	Subject located on 14th floor	Operator Notes
4:18 PM	Video Clip	Floor 14 Cam	Subject exits elevator	Video Clip
4:18 PM	Access Event	Door 14C	Forced door alarm	Access Logs

You can add as many rows as needed. Most investigations contain 20-60 timeline entries.

Step-by-Step: How to Build a Timeline Manually

If you are using traditional systems, here’s the recommended method:

Step 1 - Gather Base Logs

Start with:

• Access logs (all events in ±15 min window)
• Elevator logs
• Alarm logs
• Visitor logs (if applicable)

Step 2 - Pull Relevant Video

Locate:

• Entrance cameras
• Lobby / turnstile cameras
• Floor landing cams
• Elevator interior
• Any cameras mentioned in logs
• Any PTZ that pivoted due to motion

Step 3 - Identify Key Anchor Events

• Anchor events are moments you know are accurate:
• Door-granted/denied
• Alarm triggers
• First camera appearance
• Elevator arrival
• Align all other events around these.

Step 4 - Sync Clocks

Most systems drift. Perform manual alignment:

• Start with video timestamps
• Adjust elevator logs to match
• Confirm with a second video source

Step 5 - Build Narrative Clusters

Group events by:

• Initiating event
• Movement patterns
• System responses
• Operator actions

Step 6 - Assemble Final Timeline

• Order events chronologically.
• Add summary notes and corrective actions.

A Real-World Example (Before vs. After BluSKY)

Scenario: A person enters the lobby after hours.

❌ Before BluSKY (Disparate, Manual)

8:03 PM - Access denied at Door A 8:03 PM - Video shows a person at the turnstiles 8:05 PM - Elevator logs show Car 4 went to Floor 9... but timestamp is 90 seconds off 8:06 PM - Operator discovers an alarm at Door 9B 8:08 PM - Camera 9B shows door being forced 8:11 PM - Security responds

Total timeline assembly time: 2-4 hours Gaps: Elevator drift, missing snapshots, unclear path

✔ After BluSKY (Unified, Automatic)

8:03 PM - Access denied → SceneIT auto-snapshot 8:03 PM - BluEYES identifies subject + tracks movement 8:03 PM - Elevator logs synced in real-time 8:06 PM - Door forced on Floor 9 → auto snapshot 8:07 PM - SummarEYES builds unified timeline 8:07 PM - Security receives complete bundle

Total timeline assembly time: 30 seconds Gaps: None - all systems unified, synced, automated

Common Timeline Challenges & How BluSKY Solves Them

1. Time Drift Between Systems

The problem: Logs don’t align.

BluSKY solution: Unified cloud-time ensures synchronized timestamps across access, video, elevators, alarms, and AI.

2. Missing Snapshots or Video Clips

The problem: Critical moments never recorded.

BluSKY solution: SceneIT captures snapshots automatically when events occur.

3. Elevator Activity Missing Entirely

The problem: Most platforms don’t integrate elevator movement.

BluSKY solution: Turnstile → elevator → floor arrival all included in the evidence bundle.

4. Operators Spending Hours Reconstructing Events

The problem: Manual review is slow and error-prone.

BluSKY solution: SummarEYES auto-generates a unified timeline with all correlated evidence.

5. Inconsistent Reporting Formats

The problem: Every operator builds timelines differently.

BluSKY solution: Standardized, cross-system timeline output.

BluSKY’s Automated Timeline (SummarEYES)

SummarEYES automatically produces a timeline including:

• Access
• Video
• Elevator
• Alarms
• AI analytics
• Snapshots
• Operator actions
• System status

In one clean, downloadable bundle.

This eliminates:

• Manual export
• Time drift
• Inconsistent formats
• Missing evidence
