Forward looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.
The sensors installed in forward-looking infrared cameras—as well as those of other thermal imaging cameras—use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create a "picture" assembled for video output.
They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm).
Infrared light falls into two basic ranges: long-wave and medium-wave. Long-wave infrared (LWIR) cameras, sometimes called "far infrared", operate at 8 to 12 μm, and can see heat sources, such as hot engine parts or human body heat, a few miles away. Longer-distance viewing is made more difficult with LWIR because the infrared light is absorbed, scattered, and refracted by air and by water vapor.

Drone with FLIR Records House Burning Down
Woke in my warm bed
Just in time for all the brilliant red lights
They were streaming through my half shuttered windows
Christmas lights in time with my stuttered brain waves
The door knob was glowing
All my photographs were rippled and melting
Through the walls I could hear panicked voices
They seemed to say, go back to bed there's no choices
And nowhere not burned out
The fireman calls out, we've got another smoking
Umbrella left in the hallway
And the fireman calls out, we've got another smoking
Umbrella left here
I gave no answer
To all their shouted questions, just lay back choking
Didn't want to stay but my bed was on fire
Instead of screaming, I fell back into dreamland
Blinking and sighing
The fireman calls out, we've got another smoking
Umbrella left in the hallway
And the fireman calls out, we've got another smoking
Umbrella left here
I don't wanna leave [Incomprehensible]
I never believed in what happened to [Incomprehensible]
The fireman calls out, we've got another smoking
Umbrella left in the hallway
And the fireman calls out, we've got another smoking
