Infrared Cameras - How do they work?

Infrared cameras help us see things we can’t normally see by using heat instead of light.

Imagine you're in a dark room, and your friend is hiding behind the couch. You can't see them because it's too dark, but if they're warm, like after playing hide-and-seek for a while, you might feel their warmth on your hand. That’s kind of how infrared cameras work!

Normal cameras use light to take pictures. But infrared cameras use heat, or infrared light, a type of light we can't see with our eyes, but we can feel.

These cameras have special sensors that pick up the heat coming from objects. Like how your skin feels warm when you're near a fire, these sensors feel the heat from things around them and turn it into pictures.

Infrared cameras are like heat-sensitive eyes. They help people see in the dark, find lost animals, or even check if a wall is hot, like when your house is leaking heat during winter!
