How Does Surveillance Work? What to Expect When You Hire a PI

The surveillance scenes in movies — a PI with a telephoto lens catching a cheating spouse in seconds — bear almost no resemblance to how professional surveillance actually works. Here's what real surveillance looks like, from planning to evidence delivery.

Before the Surveillance Begins: Planning

Professional surveillance starts with intelligence gathering, not cameras. Before any field work, we collect what we can about the subject's habits, address, vehicle, workplace, and likely schedule. That information shapes when and where to establish surveillance positions for maximum effectiveness.

A poorly planned surveillance operation wastes time and budget. A well-planned one often captures what the client needs in the first session.

What Types of Surveillance We Conduct

Stationary Surveillance

Observation from a fixed position — typically a vehicle parked with a clear sightline to the subject's home, workplace, or a location they regularly frequent. Best for capturing daily routines, documenting activities at a specific location, or establishing that a subject is present at a particular address.

Mobile Surveillance (Following)

Tracking a subject's movements from location to location. Mobile surveillance requires multiple vehicles or careful single-vehicle technique to avoid detection. It's used to document where a subject goes, who they meet, and what they do outside their home.

Covert Photography and Video

All surveillance includes GPS-timestamped photographic and video documentation. The goal is to capture clear, identifiable images of the subject and their activities in the context the client needs documented — not blurry long-distance shots that won't hold up in court.

What Surveillance Can and Cannot Capture

Lawful surveillance is limited to activities observable in public or from locations where the investigator has a lawful right to be. We cannot enter private property to conduct surveillance, and we cannot record inside private residences. What happens in public — who someone meets, where they go, what they do, whether they appear to have physical limitations they've claimed not to have — is fair game.

The Evidence We Deliver

After surveillance, we provide a detailed written report covering every observation, vehicle information, locations, timestamps, and descriptions of activities. We also provide the video and photographic evidence captured, properly timestamped and preserved for court admissibility.

If the surveillance captures nothing relevant to your case, we tell you that too. We don't manufacture drama where none exists.

Frequently Asked Questions

How many days of surveillance do I need?

That depends entirely on what you're trying to document. Some cases are resolved in a single session. Cases that require catching a specific behavior may require multiple sessions across several days or weeks. We'll advise you on a realistic scope based on your specific situation.

What if the subject detects the surveillance?

Detection awareness is a reality in professional surveillance. Our technique minimizes detection risk, but some subjects are surveillance-aware. If a surveillance session is compromised, we discuss strategy adjustment with the client before continuing.

Can surveillance evidence be used in court?

Yes, if it was gathered lawfully. Evidence obtained in public spaces or from locations where the investigator had lawful access is generally admissible. We document everything with court admissibility in mind.
