Private Investigator in Belmont, CA — Surveillance Is Our Specialty
Bear Witness is the private investigator in Belmont that families, attorneys, and businesses call when they need facts, not guesses. Belmont is a city of about 28,000 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 Belmont investigators plan each case around the subject’s real routine and document it with time-stamped video.
Belmont Surveillance Investigations: Our Specialty
As a Belmont 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 Belmont 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
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Northern California traffic.
Like much of San Mateo County, Belmont mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
