Los Altos Surveillance Investigations: Our Specialty

As a Los Altos 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

We follow the subject by vehicle through Los Altos and beyond, keeping distance and cover so they never know we are there.

Static Surveillance

Discreet observation of a home, workplace, or business from a lawful public vantage point, documenting who comes and goes.

Two-Investigator Teams

For careful or unpredictable subjects, two investigators trade off so the same car is never seen twice.

Every Los Altos surveillance plan is built around where your subject actually lives, works, and spends time — not a generic template.

What Our Los Altos Private Investigators Handle

Whatever the situation, the work comes down to documenting the facts lawfully and clearly.

Personal Cases

  • Infidelity & cheating spouse — discreet surveillance that gives you a clear answer, either way.

Family Law Cases

  • Divorce investigations — facts and evidence your family law attorney can use.
