Daly City Private Investigator Services, Built Around Surveillance
If you need a private investigator in Daly City, Bear Witness has been documenting the truth for California clients since 1996. Daly City is a city of about 103,000 people in San Mateo County. Surveillance is our specialty, and every case is handled by a licensed investigator — never a call center.
From infidelity and custody cases to workers’ compensation fraud and litigation support, we keep our caseload small so every Daly City client works directly with the investigator in the field — and gets a clear answer, documented to the standard California courts expect.
Surveillance Specialists Serving Daly City
Most investigations come down to one question: what is really happening? A private investigator in Daly City answers it with surveillance video, photos, and a written timeline.
Mobile Surveillance
We follow the subject by vehicle through Daly City 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.
At roughly 13,400 people per square mile, Daly City is dense — tight parking, slow traffic, and subjects who often move on foot. Our investigators plan for that.
