Surveillance

Surveillance is a critical investigative tool for obtaining actionable evidence. Whether other methods have fallen short or discretion is required, surveillance can be tailored as "static" or "mobile" with a single investigator or an expert team. Our color video and photographic stills document key events for evidence in civil or criminal action, hearings, or dispute resolutions. While virtually any investigation can incorporate surveillance, it's the experience and ethics of the investigator that ensure any evidence obtained retains genuine value and stands up to scrutiny.
