Which of the following is listed as an FMV collection advantage?

• A. Interaction with environment
• B. Limited coverage
• C. Persistent surveillance
• D. Increased observer fatigue

Answer: (C)

FMV collection excels at persistent surveillance: it provides continuous, time‑extended visibility of the same area, allowing you to watch how events unfold, track movements, and identify patterns over hours or days. This sustained view supports real-time awareness and post‑event analysis in ways that short or intermittent imagery cannot. The other options aren’t advantages of FMV: interaction with the environment isn’t how FMV is primarily used, limited coverage describes a constraint rather than a benefit, and observer fatigue is a drawback rather than an advantage.
