Field guide
All articlesThe questions people actually type into Google about heat and night vision.
Hardware Does the iPhone have a thermal camera?
No iPhone has ever had a thermal sensor, and the iPhone 17 does not either. Here is what the infrared hardware in your phone actually does.
Basics What is thermal vision?
Thermal vision is seeing the infrared light objects emit because they are warm, rather than the visible light they reflect. It is not night vision.
Comparison Night vision vs thermal — which one do you actually need?
Night vision amplifies the light that is already there. Thermal imaging senses heat and needs no light at all. They fail in opposite conditions.
Basics How does a thermal camera work?
Everything warmer than absolute zero glows in infrared. A thermal camera collects that glow, measures it with a microbolometer and paints it in colour.
