Calabasas Private Investigator Services, Built Around Surveillance
Bear Witness is the private investigator in Calabasas that families, attorneys, and businesses call when they need facts, not guesses. Calabasas is a city of about 23,000 people in Los Angeles County. We are a veteran-owned, California-licensed firm (PI #18755), and surveillance is what we do best.
Our Calabasas clients include individuals facing infidelity or a missing family member, parents in custody and support disputes, employers and insurers dealing with fraud, and law firms that need evidence and testimony. What they share is a need for discreet, lawful surveillance that holds up.
Calabasas Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Calabasas answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Calabasas and beyond, keeping distance and cover so they never know we are there.
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.
The average commute in Calabasas is about 34 minutes, so work-related surveillance often means following a route, not waiting at one address.
