Mountain View Private Investigator Services, Built Around Surveillance
If you need a private investigator in Mountain View, Bear Witness has been documenting the truth for California clients since 1996. Mountain View is a city of about 82,000 people in Santa Clara County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Our Mountain View 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.
Mountain View Surveillance Investigations: Our Specialty
As a Mountain View 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 Mountain View and beyond, keeping distance and cover so they never know we are there.
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, Mountain View mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
