Professional Observation in a High-Definition World

Surveillance is the backbone of professional investigation, and it is where experience separates results from guesswork. Our investigators conduct covert mobile and stationary surveillance using high-end optics, long-range photography, and discreet vehicle positioning to document activity without alerting the subject. Every observation is logged with date, time, and location and supported by time-stamped photo and video evidence — producing a clear, defensible record of what occurred and when.

What We Do

Our Surveillance Services

Covert Mobile Surveillance

Our investigators follow subjects across the DFW Metroplex using multi-vehicle, rotating coverage designed to avoid detection. Whether the subject is a claimant, a spouse, or a corporate employee, we maintain discreet visual contact and document movement, contact, and activity throughout the engagement.

Stationary / Fixed-Point Surveillance

When a known location is the focus — a residence, a workplace, a frequent destination — we deploy stationary surveillance using long-range optics and concealed positioning. Fixed-point operations are particularly effective for documenting regular conduct patterns, verifying routine claims, or confirming the presence of specific individuals at specific times.

Workers' Compensation & Insurance Fraud

When a claimant's reported limitations don't match their actual activity, professional surveillance provides the documented proof that adjudicators and defense attorneys need. We capture continuous, timestamped footage showing physical capabilities that contradict reported injuries — gathered and preserved to withstand challenge in court or before a claims board.

Corporate & Internal Surveillance

Internal theft, non-compete violations, unauthorized use of company assets, and misconduct by employees or contractors all require documentation gathered through methods that respect legal limits and hold up under scrutiny. We work with business owners, HR departments, and in-house counsel to design surveillance operations that produce usable findings without compromising the investigation itself.

High-Definition Video & Photo Evidence

Every Armstrong Investigations surveillance engagement produces professionally captured, date- and time-stamped documentation. Our equipment operates at a level that delivers clear, usable footage regardless of lighting conditions, distance, or subject movement — because evidence that is unclear or incomplete is evidence that gets challenged.

Multi-Operative Surveillance Teams

Evasive subjects, locations with multiple exits, and high-stakes cases where a single missed movement would waste an entire day's work call for a two-person team. Multi-operative deployments substantially increase the probability of a successful session and reduce the cost of failed single-investigator attempts across the same assignment.

Why It Matters

Surveillance That Holds Up When It Counts

Professional surveillance isn’t simply watching — it’s watching correctly, in a way that produces evidence that remains useful once it enters a courtroom, a deposition, an insurance hearing, or a custody proceeding.

The most common failure point in surveillance-based cases isn’t the subject’s behavior. It’s the documentation. Gaps in footage, unclear timestamps, inconsistent logs, or legally problematic observation methods give opposing counsel exactly what they need to undermine evidence that should have been airtight.

At Armstrong Investigations, PLLC, Jasen A. Armstrong’s law-trained (J.D.) perspective shapes how every surveillance operation is planned and documented. We build files the way a litigator thinks about them — from the end backward, starting with what the evidence needs to prove and working forward to how it needs to be captured and preserved.
