In surveillance terminology, what is the primary difference between covert and overt methods?

The primary difference between covert and overt methods in surveillance lies in the visibility and awareness of those being monitored. Covert methods entail concealing one's identity and the fact that surveillance is taking place. This means that the subjects are typically unaware that they are being observed. Such methods allow for more discreet monitoring, which can be crucial in certain situations where revealing the surveillance could compromise the results or objectives.

In contrast, overt methods involve surveillance that is open and public. The subjects are fully aware that they are being monitored, which could be done for reasons like deterrence of crime or providing a sense of security.

Understanding this distinction is fundamental in surveillance practices. It informs the strategies employed based on the goals of the surveillance operation and the consequences of the subjects knowing they are being observed. Covert surveillance is often used in investigations where subjects might alter their behavior if they were aware of the monitoring, while overt surveillance might be used in more public security contexts.
