Private Investigator in San Carlos, CA — Surveillance Is Our Specialty
Bear Witness is the private investigator in San Carlos that families, attorneys, and businesses call when they need facts, not guesses. San Carlos is a city of about 30,000 people in San Mateo County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
Our San Carlos 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.
San Carlos Surveillance Investigations: Our Specialty
As a San Carlos 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 San Carlos 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.
Like much of San Mateo County, San Carlos mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
