Your Campbell Private Investigator for Surveillance and Investigations
If you need a private investigator in Campbell, Bear Witness has been documenting the truth for California clients since 1996. Campbell is a city of about 43,000 people in Santa Clara County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Our Campbell clients include individuals facing infidelity or a missing family member, parents in custody and support disputes, employers and insurers dealing with fraud, and law firms that need evidence and testimony. What they share is a need for discreet, lawful surveillance that holds up.
Campbell Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Campbell 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
We hold position at the locations that matter to your case and record activity with time-stamped video.
Two-Investigator Teams
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
Like much of Santa Clara County, Campbell mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.

What if the investigation finds nothing?
You get an honest report that says so. A clean result still answers the question.

We can document what your spouse actually does and who they meet, with time-stamped video and a written report, and give you a clear answer either way.
