Surveillance Specialists Serving San Ramon

Most investigations come down to one question: what is really happening? A private investigator in San Ramon answers it with surveillance video, photos, and a written timeline.

Mobile Surveillance

We follow the subject by vehicle through San Ramon 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.

The average commute in San Ramon is about 35 minutes, so work-related surveillance often means following a route, not waiting at one address.
