Surveillance FAQ
Is private investigator surveillance legal in Illinois?
Yes. Supreme Investigations is a licensed Illinois private detective agency (IDFPR Agency #117.001922). Our investigators conduct surveillance from lawful public vantage points and document what happens in plain view — we never trespass, wiretap, or use illegal methods to gather evidence.
What is private investigator surveillance commonly used for?
The most common matters are infidelity and family-law disputes, child-custody and parenting-time concerns, workers' compensation and insurance-defense claims, personal-injury activity checks, cohabitation and maintenance questions, and business matters such as suspected employee misconduct. In every case the goal is the same: an accurate, documented picture of what the subject is actually doing.
What evidence do I receive from a surveillance investigation?
You receive timestamped HD video and photographs, a written chronological report describing what was observed, when, and where, and a chain-of-custody record. Evidence is delivered by secure encrypted transfer or on physical media on request, and the investigator is available to testify to how it was gathered.
How much does surveillance cost?
Manned surveillance is $200 per hour, door-to-door, with a six-hour minimum and no mileage, fuel, or report-writing fees. The price is confirmed in writing before any work begins. Covert-camera and multi-investigator coverage are quoted by scope.
Will the subject know they are being watched?
No. Surveillance is covert and conducted from lawful public vantage points using long-range equipment. Discretion is the entire point — the subject should never be aware, which is exactly why this work belongs with a trained, licensed professional.
How many hours of surveillance do I need?
It depends on the behavior you need documented and when it is likely to occur. Many matters are resolved in one to three sessions once the subject's routine is established. We give you an honest estimate during the consultation and never pad hours.
