1. Surveillance
Surveillance, in the PI world, means discreetly observing and documenting a subject’s activity, movements, and interactions to gather useful, lawful evidence without being noticed.
Why It's Important
It verifies claims, uncovers patterns, and captures time-stamped, objective proof. Cases move on what you can show, not just what you’re told.
How to Improve Surveillance Skills
Sharper methods, steadier execution. Try these:
Upgrade your kit: Clear optics, reliable low-light options, long battery life, quiet operation.
Drill tactics: Static, mobile, foot surveillance—practice routes, handoffs, and counter-surveillance awareness.
Master documentation: Time logs, brief video clips, clear stills, immediate notes. Keep it consistent.
Know the law: Privacy, audio/visual recording, location tracking limits—rules vary by jurisdiction. Check them before you roll.
Stay fit: Long sits, sudden moves, odd hours. Conditioning keeps you sharp and inconspicuous.
Learn from peers: Professional associations, case debriefs, and scenario training expose blind spots.
