Surveillance is an additional tool that investigators use in the course of obtaining evidence.  Surveillance is conducted when other investigative methods may have failed or cannot obtain pertinent evidence. Surveillance can be "static" or "mobile" and can involve one person or a team. Color video or photographic stills are obtained depicting a course of events to be used as evidence in a civil or criminal action, hearing, or for any other managed dispute resolution. Surveillance can be used in virtually any investigation; however, it is the quality and experience of the investigator that makes the ultimate difference in value of evidence obtained.

General Liability - Surveillance aids in determining the level of injury/incapacitation of a claimant to assist the insurance examiner or their defense council in analyzing the validity of a claim, and potentially to impeach testimony by the claimant/plaintiff at trial.

Child Safety / Visitation Monitoring - Occasionally, surveillance is conducted in the course of a non-custodial parental visitation to determine whether the parent is acting in a manner consistent with court mandate.
