Sometimes you can see it with WP before you'll see it with thermal.
This video from Regular Guy Training LLC highlights a key advantage of white phosphor night vision (WP NVG) over thermal imagers in specific scenarios. WP NVG can amplify existing light sources, making it effective for detecting illuminated objects or even faint outlines through barriers, which thermals might miss due to lack of heat differential. This makes WP NVG particularly useful for spotting light-emitting sources like cigarettes or cell phones, and for observing individuals who are being undisciplined with light discipline.
