18. The term "surveillance" is used in different ways. A literal definition of surveillance as "watching over" indicates monitoring the behaviour of persons, objects, or systems. However surveillance is not only a visual process which involves looking at people and things. Surveillance can be undertaken in a wide range of ways involving a variety of technologies. The instruments of surveillance include closed-circuit television (CCTV), the interception of telecommunications ("wiretapping"), covert activities by human agents, heat-seeking and other sensing devices, body scans, technology for tracking movement, and many others.
