Cupertino Private Investigator Services, Built Around Surveillance
If you need a private investigator in Cupertino, Bear Witness has been documenting the truth for California clients since 1996. Cupertino is a city of about 59,000 people in Santa Clara County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Whether you suspect a cheating spouse, need evidence for a custody or support case, are dealing with a questionable workers’ compensation claim, or represent a client who needs court-ready surveillance, our Cupertino investigators plan each case around the subject’s real routine and document it with time-stamped video.
Cupertino Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Cupertino answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Cupertino 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 Cupertino surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
