Danville Surveillance Investigations: Our Specialty
As a Danville 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
We follow the subject by vehicle through Danville 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
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Northern California traffic.
Like much of Contra Costa County, Danville mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
