Private Investigator in Big Bear, CA — Surveillance Is Our Specialty
Bear Witness is the private investigator in Big Bear that families, attorneys, and businesses call when they need facts, not guesses. Big Bear is the Big Bear Valley in the San Bernardino Mountains — the City of Big Bear Lake and the unincorporated communities around it. 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 Big Bear investigators plan each case around the subject’s real routine and document it with time-stamped video.
Big Bear Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Big Bear 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.
Because Big Bear borders Big Bear Lake, many cases here involve both communities, and we plan surveillance to cover each.
