Surveillance Specialists Serving Fairfield

Most investigations come down to one question: what is really happening? A private investigator in Fairfield 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 Solano County, Fairfield mixes residential neighborhoods with busy commercial corridors. We combine discreet residential positioning with mobile coverage on the roads in between.
