Surveillance Investigations

Discreet field observation that documents relevant activity for legal, business, and personal decisions.

A focused approach to Surveillance Investigations

Surveillance is most useful when the assignment has a concrete question: whether an activity occurred, when a person arrived, or how a sequence of events unfolded. Repeated observation without a defined objective can consume a budget without producing useful information. ISI works with clients to identify relevant times, locations, and realistic expectations before fieldwork begins.

What the investigation can include

An investigator reviews identifying information, likely schedules, and lawful observation opportunities. Field notes record timing and context, with photographs or video where conditions permit. Activity in Houston, Clear Lake, and surrounding communities may require adjustments for traffic, visibility, and changes in routine.

Clear, documented findings

The report distinguishes what the investigator personally observed from information supplied by the client. Supporting media is connected to a dated narrative, and gaps or limitations are explained rather than filled with assumptions.

What to prepare before we speak

Provide a recent photograph, vehicle description, known locations, and the activity you need documented. Explain any litigation, protective orders, safety concerns, or prior investigation that may affect the assignment.

Scope and practical limits

No investigator can guarantee that a subject will appear or that a specific act will be captured. An assignment does not authorize trespassing, unlawful tracking, or access to private accounts.
