What are the two types of surveillance?

The two types of surveillance are best classified as mobile and stationary. Mobile surveillance refers to the observation that is conducted while moving, allowing investigators to follow subjects as they go about their activities. This approach is often used in situations where the subject may change locations frequently, and maintaining a flexible position is key to gathering information effectively.

On the other hand, stationary surveillance involves maintaining a fixed position to observe a specific location or individual. This method allows for careful monitoring of activities over time without the need to follow the subject directly. Both types of surveillance are critical in investigations, as they can be utilized in combination to enhance the overall effectiveness of the information-gathering process.

The other options, while relevant to certain aspects of surveillance, do not encompass the primary distinctions that are most critical in investigative practice. Static and dynamic, for instance, might refer to other contexts of observation rather than the mobility aspect. Visual and audio focus on the sensory modalities used rather than how the surveillance is conducted. Remote and proximate highlight the distance from which surveillance is executed but do not directly address the movement aspect that is central to the classification.
