Why it matters
Anomaly detection starts with knowing normal
Early recognition buys decision time
Familiar patterns reduce real hesitation
Small changes precede bigger trouble

What a Baseline Is

  • Learn the usual activity on your block
  • Know who belongs and when they move
  • Track common sounds and notable changes

Why It Matters

  • Spot anomalies against a known normal
  • Reduce hesitation during a real problem
  • Catch small shifts before bigger trouble

Build a Profile

  • Note regular vehicles and their spots
  • Track neighbor activity, delivery, service rhythms
  • Learn typical foot traffic and pace

Map the Terrain

  • Identify observation points and sightlines
  • Mark entry, exit, and choke points
  • Plan a fallback path to safer ground

Day vs Night

  • Daytime brings deliveries and steady traffic
  • Night reduces traffic; idle vehicles stand out
  • Learn how lighting and sound shift

What Breaks Pattern

  • Unknown vehicle parked far too long
  • Repeated slow drive-bys or watching figures
  • Tampered doors, new faces lingering without errand
