Why Do Cameras See Infrared A thermographic camera is a device that creates an image using infrared radiation similar to a common camera that forms an image using visible light. But it can be positioned around under darkness infrared measures the heat coming from objects in the area and this can be read by the camera even no light required. Infrared lights are commonly used in remote controls. Community Answer Humans produce heat - otherwise known as infrared radiation - which an infrared camera catches.
In infrared light hot things look bright yellow and orange. You eyes cannot see wavelengths LONGER than 720 nm. Thermal imaging cameras make small temperature differences visible.
But it can be positioned around under darkness infrared measures the heat coming from objects in the area and this can be read by the camera even no light required.
Heat also called infrared or thermal energy and light are both parts of the electromagnetic spectrum but a camera that can detect visible light wont see thermal energy and vice versa. Why Do Cameras See Infrared They produce an image in the darkest of nights and can see through light fog rain and smoke to a certain extent. A thermographic camera is a device that creates an image using infrared radiation similar to a common camera that forms an image using visible light. Hence a good camera would only detect EM radiation in the visible light spectrum between 400nm and 700nm.
Most forms of infrared energy can be seen and measured only with the use of specialized equipment such as infrared cameras and telescopes or night-vision goggles. Thermal imaging cameras are excellent tools for night vision. The night vision camera that uses infrared technology comes with an infrared cut filter. In infrared light hot things look bright yellow and orange. A thermographic camera is a device that creates an image using infrared radiation similar to a common camera that forms an image using visible light.

FYI The infrared light captured by digital still cameras is reflective. Light reflecting off of nearby surfaces either inside or out of the cameras field of view is also a cause as is light reflecting off of tiny particles in the air. Most cameras are designed to capture an image of what people can see. The infrared camera measures and displays a thermal profile of objects in relation to the temperature of surrounding objects. It has to do with the frequency of the light waves.
Infrared lights are commonly used in remote controls. Certain models of Ring devices have a night vision feature that allows you to see through the camera in low light conditions. The night vision camera that uses infrared technology comes with an infrared cut filter. In other words the still camera does not see heat or radiating infrared light like the night vision video cameras you might see on police shows. Heat also called infrared or thermal energy and light are both parts of the electromagnetic spectrum but a camera that can detect visible light wont see thermal energy and vice versa.
