(916) 672-2660 A night vision camera is a tool that enhances objects during the night so that people can see the things around them better. There are two different ways that night vision cameras can work. The most basic way is by drawing out the small amount of light coming from objects and amplifying it. The more complicated way is known as thermal imaging. In this case, the higher end of the infrared light spectrum is trapped and emitted as heat. The hotter something is, the brighter it is shown through the camera. This is different than the light you normally see, because it is not being reflected off of an object or person; Instead, it is being detected and enhanced by the night vision camera.
