Which of the following is a key consideration when conducting surveillance?

Maintaining a low profile and being discreet is essential when conducting surveillance because it helps prevent the target from becoming aware of the investigator's presence. Surveillance aims to gather information without alerting the subject, and being discreet allows for a more effective observation, minimizing the risk of compromising the investigation.

Choosing a location solely based on convenience might not take into account factors such as visibility, safety, or the ability to obtain a clear view of the target's activities, which are critical for successful surveillance. Following the target without rest could lead to fatigue and may hinder the investigator's ability to observe effectively, along with increasing the likelihood of detection. While high technology can aid surveillance, relying on it at all times can be impractical or unnecessary; sometimes, traditional methods are more effective in certain situations. Thus, being discreet remains the most critical factor in ensuring successful surveillance.
