Private Investigator in Alameda, CA — Surveillance Is Our Specialty
If you need a private investigator in Alameda, Bear Witness has been documenting the truth for California clients since 1996. Alameda is a city of about 77,000 people in Alameda County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
Our Alameda 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.
Why Surveillance Is at the Heart of Every Alameda Case
Most investigations come down to one question: what is really happening? A private investigator in Alameda 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
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 Alameda County, Alameda mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
