1. Surveillance

Surveillance, for a field investigator, is the disciplined observation of people, places, or assets to gather information, verify claims, and capture admissible evidence—usually without being noticed.

Why It's Important

It validates facts, tracks behavior over time, and uncovers patterns that interviews alone won’t reveal. Solid surveillance sharpens decisions and anchors cases with concrete proof.

How to Improve Surveillance Skills

Refine your edge with deliberate practice and tight tradecraft:

1. Master your gear: Stay current on cameras, optics, audio, and vehicle setups. Test in low light, high traffic, and bad weather.

2. Know the law: Keep up with jurisdictional rules on privacy, tracking, recording, and consent. Build habits that protect admissibility.

3. Disappear in plain sight: Rotate covers, vary routes, dress for the area, and manage timing. Don’t form patterns. Blend, then blend again.

4. Sharper observation: Train your eye for baselines and anomalies—small deviations that matter later.

5. Digital angles: Learn open-source research methods, metadata cues, and safe collection tactics across platforms.

6. Network: Engage with professional associations and peer groups. Swap tactics. Compare notes on changing trends.

7. Stay fit: Long days, longer nights. Stamina and steady nerves matter when you need to move or hold position.

8. Document ruthlessly: Time-stamp, geo-tag when appropriate, and write reports that stand up under scrutiny.
