Surveillance involves paying close and sustained attention to another person.It is distinct from casual yet focused people-watching, such as might occur at a pavement cafe, to the extent that it is sustained over time. Furthermore the design is not to pay attention to just anyone, but to pay attention to some entity (a person or group) in particular and for a particular reason. Nor does surveillance have to involve watching. It may also involve listening, as when a telephone conversation is bugged, or even smelling, as in the case of dogs trained to discover drugs, or hardware which is able to discover explosives at a distance.
