Surveillance That Holds Up Under Scrutiny

Discreet, lawful, thoroughly documented surveillance across Denver and the Front Range — for attorneys, insurance carriers, employers, and private clients.

The core of what we do

Evidence is made or lost in the field

Most cases turn on the gap between what someone reports and what they actually do. Surveillance is how that gap gets documented.

Our investigators conduct covert observation from public vantage points, capture continuous time-coded video, and log every period observed — including the hours in which nothing happened. An edited highlight reel invites exactly the cross-examination you were trying to avoid, so we do not produce one.

We report accurately whether or not the result helps the client who hired us. An investigator who tells you what you want to hear is an investigator who gets impeached, and takes your case down with him.

Where surveillance applies

Surveillance case types

Personal Injury Claims

Activity and mobility documentation for defense counsel and carriers evaluating reported restrictions, including pre-IME and pre-deposition activity checks.

Workers’ Compensation

Verification of claimed limitations, secondary employment, and return-to-work capability for employers and self-insured carriers.

Child Custody

Documentation of supervision, living conditions, and parenting-plan compliance in a form Colorado family courts can weigh.

Infidelity & Cohabitation

Discreet documentation of a pattern of conduct, conducted over sufficient time to establish more than a single observation.

Employee & Fraud Matters

Time-theft, competing employment, and internal fraud where documented observation is the only way to establish what is happening.

Evasive Service of Process

Pattern-of-life observation to establish when a subject who is avoiding service can actually be served.

How we work

The limits we work within

We record what can be seen from places we are lawfully entitled to be. We do not trespass, we do not record inside a residence, we do not use pretext to gain entry, and we do not make contact with the subject.

Video obtained the wrong way is not merely useless — it hands the other side a claim of its own. Working inside those limits is not a constraint on results; it is the reason our results survive.

  • Continuous date and time coding on all video
  • Complete observation logs, including unproductive periods
  • Written reports separating observation from inference
  • Investigators prepared to testify to how evidence was obtained
