What is the main difference between covert and overt in-person surveillance?

The primary distinction between covert and overt in-person surveillance lies in their visibility to the target being observed. Covert surveillance is designed to be concealed, which means that the individuals being surveilled are not aware that they are being monitored. This approach allows for the collection of information without the subject's knowledge, which is often crucial in scenarios where awareness could alter behavior or compromise the objectives of the surveillance.

In contrast, overt surveillance is evident and detectable; the subjects are aware that they are being watched. This can include uniformed security personnel or prominently placed cameras that serve as a deterrent to illicit activities and provide a sense of security to the public.

Understanding this difference is essential for professionals in the security field because the choice between covert and overt surveillance can significantly impact the effectiveness and legality of their surveillance strategies.
