How do Infrared security cameras work? Infrared Sensors (or IR) detect infrared radiation, which is essentially the byproduct of heat. Specifically, electromagnetic radiation has a wavelength longer than visible light but shorter than a microwave, which means that people cannot see it or be damaged by it. Infrared (or thermal) imaging is used in many devises such as smart missiles, night vision goggles, and television remotes. Other scientific uses involve using infrared light to predict the weather or study the formation of stars. Obviously, visible light is not necessary to produce heat, which is why infrared cameras work so well at night.
Infrared cameras come with many different numbers of infrared lights built into the lens. Some have as many as 64 or as few as 6 bulbs, but the number of bulbs is not the only thing to consider. The size of the infrared bulb is important as well. Generally the more infrared light, in both size and number, that a infrared security camera has the farther that you will be able to see with the camera.
