What type of surveillance is most likely to attract attention in a residential area?

Obvious tracking of individuals is likely to attract attention in a residential area because it involves visible actions or behaviors that can be easily noticed by the public or residents. This type of surveillance typically includes following someone in a manner that is not subtle, such as closely following them for an extended period or using marked vehicles. Such conduct is easily perceived as suspicious, leading to potential inquiries from neighbors or law enforcement about the nature of the behavior.

In contrast, discreet observation involves methods that are intended to go unnoticed, which minimizes the chance of drawing attention. The use of high-tech equipment might attract attention if it is overtly used, but often such equipment can also be employed discreetly or from a distance. Casual walking tends to blend in with regular pedestrian activity and thus does not raise suspicion. Therefore, obvious tracking stands out as the method most likely to cause alarm in a neighborhood setting.
