Private Investigator in Livermore, CA — Surveillance Is Our Specialty
Bear Witness is the private investigator in Livermore that families, attorneys, and businesses call when they need facts, not guesses. Livermore is a city of about 86,000 people in Alameda 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 Livermore 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 Livermore Case
As a Livermore 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
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.
Every Livermore surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
