OSH Security Practice Test

The correct answer highlights the core distinction between covert and overt surveillance techniques, focusing on the visibility and role of the security personnel involved. Covert surveillance operates under the principle of secrecy, meaning that the security personnel or surveillance methods are not readily apparent to the subjects being monitored. This allows for the observation of behaviors or actions without alerting those being watched, which can be crucial in certain security situations where discretion is necessary.

In contrast, overt surveillance is characterized by the obvious presence of security personnel, typically in visible uniforms. This visibility serves as a deterrent to potential wrongdoing and provides a sense of security to the public. The presence of security guards in a clear and identifiable manner reinforces the authority of the security team and contributes to a safer environment.

The other options do not capture the essential definitions of these two types of surveillance. Conditions such as the timing (day or night) or the location (inside or outside) are not the fundamental criteria that differentiate covert from overt surveillance; it's primarily about whether the surveillance is conducted discreetly or with full visibility of the security personnel involved.
