Infrared Cameras Capture Fog Droplets, Not Summer Snow
Infrared Cameras Capture Fog Droplets, Not Summer Snow
US · Published Jul 4, 2026
Security cameras equipped with infrared night vision often capture tiny droplets of moisture in the air, which can appear as white specks on video footage.
These droplets, commonly found in fog, are suspended in the air due to their small size and light weight.

Impact & Risks

This visual effect on security cameras can lead to confusion among users, who may misinterpret the footage as evidence of unusual weather events like summer snow or unexpected rain. While harmless, the misunderstanding could prompt unnecessary concern or inquiries. It is important to note that these reflections are purely optical phenomena caused by infrared light interacting with fog droplets and do not indicate actual precipitation.
