Your Alamo Private Investigator for Surveillance and Investigations
Looking for a private investigator in Alamo? Bear Witness Private Investigators is a California-licensed firm (PI #18755) that has specialized in surveillance since 1996. Alamo is an unincorporated community of about 14,000 people in Contra Costa County, and it is part of our regular coverage across Northern California.

Why Surveillance Is at the Heart of Every Alamo Case
As a Alamo 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
We hold position at the locations that matter to your case and record activity with time-stamped video.
Two-Investigator Teams
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Northern California traffic.
Like much of Contra Costa County, Alamo mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
