Quizplus · Accepted Answer

Surveillance and covert operations rely on a person's senses, particularly their ability to see and hear in order to gather information and evidence. Invigilation refers to close supervision, often in an educational or testing setting. Electronic evidence and obtaining physical evidence both involve gathering information through technological or physical means, rather than relying on a person's senses.
