Napa Private Investigator Services, Built Around Surveillance
Bear Witness is the private investigator in Napa that families, attorneys, and businesses call when they need facts, not guesses. Napa is a city of about 79,000 people in Napa 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 Napa 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 Napa Case
Most investigations come down to one question: what is really happening? A private investigator in Napa answers it with surveillance video, photos, and a written timeline.
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
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
Every Napa surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
