- Static observations
- Dynamic observations
- Preventive observations
In a static observation, hidden cameras are usually placed. Static observation often takes place from one or several fixed objects, from which a subject consisting of one or more persons or an object is observed.
In a dynamic observation, the object consisting of a person or an article is followed, on foot or by means of transport, such as a car or motorcycle.
In a preventive observation the person or the object is observed before departure, for example to work or at an object before departure to the customer. This allows suspicious persons or events to be detected at an early stage.
During observation researches, Digitale Opsporing closely collaborates with an agency whose employees have earned their spurs in observation teams of various digital government services, such as the Police, FIOD (Fiscal Information and Investigation Service) National Crime Investigation Service and the Royal Netherlands Marechaussee.
