Surveillance investigations involve the observation and video documentation of a specific individual or location to monitor activities during a designated timeframe. Our services are exclusively available in Nassau and Suffolk Counties on Long Island.

We provide comprehensive video and photographic evidence, complete with time and date stamps, accompanied by detailed written reports. This documentation supports and corroborates our investigators’ observations, serving as admissible physical evidence in legal proceedings to bolster your claim or case. Upon request, our investigators are prepared to provide court testimony to substantiate our findings.

Surveillance can be utilized to verify or refute suspicions of infidelity or cheating spouses, detect insurance fraud, address frivolous lawsuits, assess character, and support corporate, legal, and family law cases. It is also effective in monitoring child welfare and whereabouts, assisting in child custody or support cases, determining alimony, and more.

Background checks are instrumental in validating or confirming residency and address history, uncovering criminal records and ongoing court cases, identifying business affiliations or ownership, and detecting bankruptcies or judgments. They also encompass DMV history, social media searches, cell phone history or ownership verification, and internet research. We conduct background checks solely for legitimate and legal purposes, utilizing trusted and secure databases inaccessible to the general public. This enables us to obtain current information about the subject, aiding in delivering positive outcomes for your case.
