Private Investigator in Millbrae, CA — Surveillance Is Our Specialty
Bear Witness is the private investigator in Millbrae that families, attorneys, and businesses call when they need facts, not guesses. Millbrae is a city of about 23,000 people in San Mateo County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
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 Millbrae 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 Millbrae Case
As a Millbrae 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
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
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Northern California traffic.
Like much of San Mateo County, Millbrae mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
