El Cajon Surveillance Investigations: Our Specialty
As a El Cajon private investigator, surveillance is the core of what we do. We document activity legally, discreetly, and in a way that holds up in court.

Two-Investigator Teams
Team surveillance covers multiple exits and keeps a moving subject in sight in heavy Southern California traffic.
Every El Cajon surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.
