Modesto Surveillance Investigations: Our Specialty
As a Modesto private investigator, surveillance is the core of what we do. We document activity legally, discreetly, and in a way that holds up in court.
Mobile Surveillance
We follow the subject by vehicle through Modesto and beyond, keeping distance and cover so they never know we are there.
Static Surveillance
Discreet observation of a home, workplace, or business from a lawful public vantage point, documenting who comes and goes.
Two-Investigator Teams
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
Every Modesto surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
