[SESSION_127] SecurityAgent: Implement Cross-Camera Correlation (Phase 23)

Feature: Cross-Camera Threat Correlation

Component: SecurityAgent (/agents/security_agent/)
Severity: 🔴 CRITICAL BLOCKER
Session: SESSION 127 (Definition of Done)
Current Status: Stub returns None immediately
Target Phase: Phase 23

Context

Multi-camera threat detection requires correlating suspicious behavior across camera boundaries. Currently, cross-camera analysis returns None, missing critical multi-zone threats.

Requirements

• Track person/object movement across camera boundaries
• Detect impossible transitions (e.g., teleportation)
• Correlate events across time and space
• Generate cross-camera incident reports
• Handle camera topology and FOV overlaps

Impact

Without this feature:

• Cannot detect multi-camera threats
• Each camera analyzed in isolation
• Multi-zone sophisticated attacks undetected

Effort Estimate

• Cross-camera matching: 8-10 hours
• Temporal correlation: 3-4 hours
• Testing: 2-3 hours
• Total: 12-15 hours

Technical Approach

• Camera topology mapping
• Person re-identification across views
• Temporal window correlation (0-5 seconds transit)
• Threat propagation across camera network
