What type of surveillance involves following one or more subjects?

Rolling surveillance is characterized by the active following of one or more subjects as they move. This type of surveillance allows the observer to adapt and respond to the subjects' changing locations and behaviors in real time, providing valuable insights into their activities. It's typically employed in investigations where it's crucial to track a subject's movements over time, especially in scenarios like human trafficking cases where patterns may need to be established or corroborated with other evidence.

Static surveillance, while effective in certain contexts, generally involves monitoring a fixed location rather than following individuals. CCTV surveillance relies on cameras to capture footage without a physical person following the subject. Remote surveillance refers to observing individuals or activities from a distance, often through surveillance technology, rather than through direct, active tracking. This makes rolling surveillance particularly relevant for dynamic situations where active monitoring is necessary.
