What must a security guard do when utilizing overt surveillance methods?

When utilizing overt surveillance methods, it is essential for a security guard to clearly identify their presence. Overt surveillance is characterized by being open and observable; the subjects of surveillance are aware that they are being watched. This approach is often used in situations where transparency is crucial, such as maintaining order in public spaces or deterring potential criminal activity. By making their presence known, security personnel can effectively project authority and promote feelings of safety among the public.

In contrast, remaining unnoticed is associated with covert surveillance, where the goal is to observe without revealing one's presence. Using advanced technology is not a requirement of overt surveillance; rather, it can sometimes complicate the straightforward nature of this method. Depicting an undercover persona is also related to covert operations, which again is not applicable when the security guard's presence is to be made clear. Hence, identifying oneself as a security guard aligns with the principles of overt surveillance.
