TechnicalTechnical Surveillance encompasses digital photography and video/audio recordings. Examples of these are surveillance cameras used by businesses and dash cameras used by both police officers and private investigators.
Overt vs. CovertAn example of overt investigation includes the security cameras businesses use that deter clients from stealing. Covert investigation, however, is undetected, like an undercover detective trailing a subject
Mobile vs. StationaryMobile investigation involves detectives following their subjects, whether on foot or in a vehicle. Stationary investigation is remaining in one location, which could include watching the subject from a parked car.
