Surveillance Specialists Serving Fontana
As a Fontana 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
For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.
The average commute in Fontana is about 33 minutes, so work-related surveillance often means following a route, not waiting at one address.
