Fremont Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Fremont answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
Experienced drivers who anticipate turns and freeway exits, so your subject is documented from stop to stop.
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 Fremont surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
