The choice of observing the physical environment and using situation awareness stands out as a valid surveillance technique because it emphasizes the importance of being alert to one's surroundings and understanding the context in which an event is occurring. This approach allows security officers to identify potential threats or suspicious behavior without intruding on individuals’ privacy or employing invasive methods.

Being aware of the physical environment helps security personnel assess risks, recognize unusual activity, and respond appropriately to any incidents. This technique aligns with professional ethics in security practices, focusing on preventative measures and situational understanding rather than engaging in actions that could infringe on an individual's rights or lead to confrontation.

In contrast, the other methods mentioned compromise legal and ethical standards. For instance, using parabolic microphones to listen in on private conversations is generally considered an invasion of privacy and unlawful without proper consent. Similarly, using telescopes to spy on residents not only breaches their privacy but can also result in legal repercussions. Lastly, closely following a vehicle with the purpose of intimidation can lead to dangerous confrontations and is typically classified as stalking, which is illegal. Thus, the emphasis on situational awareness and interpretation of the environment stands as the only appropriate and lawful surveillance technique in this context.
