Does the IR camera work properly at night?
Infrared cameras have a wide range of applications in many fields, such as wildlife research, environmental monitoring, security monitoring, etc. Due to its ability to shoot in low visible light conditions, infrared cameras have become an important tool for night shooting. However, some people may wonder, will an infrared camera work properly at night?This article will go into more detail about this issue.
First of all, we need to understand how infrared cameras work. Infrared cameras use special sensors and processors to sense the infrared rays emitted or reflected by the target object and convert them into electrical signals to generate images. These sensors are usually made of some special materials, such as lead selenide, silicon germanium, etc., which are able to sense infrared radiation and convert it into an electrical signal.
Since the wavelength of infrared light is longer than that of visible light, the image captured by an infrared camera is a thermal image, usually displayed in grayscale or pseudo-color. At night, normal cameras may not work properly due to poor light, but infrared cameras are not affected by visible light, so they can work normally at night.
In addition, to ensure that infrared cameras can work properly at night, some cameras are also equipped with thermal imaging capabilities. The thermal imaging function can generate an image by sensing the temperature difference of the target object. At night, the temperature difference of the target object will be more pronounced due to the lower ambient temperature, so the thermal imaging function can better reveal the shape and contours of the target object.
In conclusion, the IR camera works fine at night. Since it is not affected by visible light, infrared cameras have become an important tool for night shooting. At the same time, some infrared cameras are also equipped with thermal imaging, which can better reveal the shape and contours of the target object.
