What is the detector resolution of the recommended infrared camera in the scenario?

• A. 1280x1024
• B. 640x512
• C. 320x240
• D. 1024x768

Answer: (B)

Detector resolution refers to how many picture elements the infrared detector has, which determines how much spatial detail you can see in the image. A resolution of 640x512 gives a solid balance for entry-level infrared work: it provides clearer, more discernible features than lower-res options, allowing you to identify targets and assess scenes effectively at typical training distances. Higher resolutions (like those with more pixels) can provide even sharper images, but they come with higher costs, larger file sizes, and more demanding processing, which isn’t needed for Level 1 practice. Lower resolutions would miss finer details and could hinder accurate interpretation. So, 640x512 is the practical, capable choice for this scenario.
