Cerritos Surveillance Investigations: Our Specialty
Most investigations come down to one question: what is really happening? A private investigator in Cerritos 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
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 Southern California traffic.
The average commute in Cerritos is about 33 minutes, so work-related surveillance often means following a route, not waiting at one address.
