Why Hire a Licensed Private Investigator for Surveillance?

Surveillance is often misunderstood—and frequently misused when done by amateurs. In California, surveillance must be conducted within strict legal limits, and failure to follow them can jeopardize your case.


At Bonnington PI, we are fully licensed and trained in California surveillance law, ensuring everything we document is collected legally, ethically, and professionally.

Legal Compliance

We never cross legal boundaries that could invalidate your evidence. That means:

  • No entering private property without permission
  • No GPS trackers without proper legal authorization
  • No audio recordings without all-party consent (per California’s two-party consent law)

Violating these rules can result in evidence being thrown out—or worse, legal exposure for the client. We protect you and your case by staying within the law.

Safety and Discretion

Following someone is far more complex than it seems. Our team uses

  • Vehicle changes to avoid detection
  • Rotating operatives for long-term assignments
  • Strategic positioning to maintain visual contact discreetly

Surveillance is conducted with zero confrontation and maximum professionalism.

High-Quality, Court-Ready Evidence

We use HD video, DSLR cameras, and night-vision lenses to capture clean, time-stamped images and video—including integrity shots that clearly identify the subject and their behavior.

Detailed Professional Reporting

Each case includes a comprehensive report that outlines

  • Time and location of each observation
  • Subject behavior
  • Supporting visual evidence (photos/videos)
  • Legal considerations or anomalies

These reports are formatted for use in family court, civil litigation, or criminal defense.
