Surveillance involves watching people, vehicles, places or objects, to obtain information concerning the identities and activities of individuals, which can be overt or covert.

Video, photographic and/or audio evidence provides compelling information in a court room and can often result in an early settlement or resolution of a case. Evidence of this kind is used by law firms, insurance companies and others when it comes to personal injury, employment law, suspected theft or fraud and, where appropriate, other cases.
