Workers' Compensation Surveillance in Chicago
Supreme Investigations provides workers' compensation surveillance in Chicago and Chicagoland for insurance carriers, third-party administrators, SIU units, and defense counsel. When a claimant's reported limitations don't match their observed activity, timestamped HD video, chronological written logs, and chain-of-custody documentation resolve the discrepancy and hold up under arbitrator scrutiny at the Illinois Workers' Compensation Commission. This service pairs with full Surveillance Investigator Chicago coverage, long-duration Unmanned Surveillance Chicago camera placement, and focused Vehicle Sighting Chicago assignments when a single confirmed location is enough.
Authority that matters in court: we are licensed by the Illinois Department of Financial & Professional Regulation (IDFPR) under 225 ILCS 447 as Agency #117.001922 and Detective #115.002750.
Workers' compensation fraud costs Illinois employers and insurers hundreds of millions of dollars annually, and a single well-documented claimant contradicting their reported restrictions can reshape how a claim is valued at arbitration. Supreme Investigations conducts lawful, court-ready workers' comp surveillance for carriers, TPAs, SIUs, and defense attorneys across Chicago, Cook County, DuPage County, Naperville, Schaumburg, and all of Chicagoland — producing the kind of factual record that holds up in Illinois Workers' Compensation Commission proceedings and Independent Medical Examinations.
What We Document
Physical Activity Documentation
We document claimant movement, lifting, carrying, bending, climbing, and sustained exertion on timestamped HD video that can be compared directly against the functional limitations reported in medical filings, FCE reports, and claim documents.
Undisclosed Employment While on Claim
We document regular attendance at a business address, physical labor at a construction site, cash-paid side work, or unreported self-employment during the claim period, all of which is inconsistent with the claimed inability to work.
Daily Activity Patterns
Multi-session surveillance establishes a behavioral pattern: where the claimant goes, what they do, and how they move. Pattern documentation is substantially more persuasive to Illinois arbitrators than a single-session observation.
Written Surveillance Reports
Our detailed chronological reports document all observed activity, vehicle information, locations visited, and investigator observations, formatted for direct use in IME preparation, depositions, 19(b) petitions, and IWCC hearings.
Documented Case Example
Claimant Observed Performing Unrestricted Physical Labor — Lumbar Spine Claim
A third-party administrator retained Supreme Investigations to conduct surveillance on a claimant who had filed a workers' compensation claim for a lumbar spine injury. The claimant had reported inability to perform any lifting, bending, or sustained physical activity. Claim payments had been ongoing for several months with no return-to-work projection and treatment escalation pending.
Our investigators deployed mobile surveillance over three separate sessions timed around the claimant's known home address. On the first session, the claimant was observed leaving the residence and driving to a residential construction site. Over the course of the morning, the subject was documented carrying lumber, operating hand tools, and working in a sustained bent-over position for extended periods — activity directly contradicting the reported functional limitations.
Subsequent sessions confirmed the pattern. The claimant returned to the same site and performed similar physical work on two additional days. Each session produced timestamped video documentation, written activity logs, and still photographs of the subject performing specific tasks.
The resulting evidence package was delivered to the TPA's defense counsel and used in the claims review process. The documentation provided a factual, independently verified record of the claimant's actual physical capabilities — significantly different from what had been represented in medical filings.

Call directly to discuss assignment scope, scheduling, and documentation requirements. We work alongside claims adjusters, TPAs, SIUs, and defense attorneys from initial surveillance through deposition and IWCC hearing support.
Our Surveillance Process
We review the claim details, medical restrictions on file, claimant address, vehicle information, and any known schedule or activity patterns. Scope, session timing, and deliverables are confirmed in writing before deployment.
Licensed investigators deploy to the subject's location using mobile and stationary surveillance techniques. Multiple camera systems and long-range documentation equipment capture activity without detection.
All observed activity is logged in a written chronological report with timestamped video and photographs. Reports are formatted for direct use by claims adjusters, defense counsel, and IME physicians.
The investigating PI is available for depositions, arbitration hearings, and trial testimony. All documentation is maintained in a format that supports chain-of-custody requirements for evidentiary use at the IWCC.
