Private Investigator in San Jose, CA — Surveillance Is Our Specialty
If you need a private investigator in San Jose, Bear Witness has been documenting the truth for California clients since 1996. San Jose is a city of about 990,000 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 San Jose investigators plan each case around the subject’s real routine and document it with time-stamped video.
Why Surveillance Is at the Heart of Every San Jose Case
Most investigations come down to one question: what is really happening? A private investigator in San Jose 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 San Jose surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
