The other way that night vision technology works is through a process known as thermal imaging. This process works by capturing the upper end of the infrared light spectrum. This part of the light spectrum is emitted in the form of heat, as opposed to light as we might recognize it. The warmer an object is the higher amount of this light is emitted.

Night vision cameras provide high quality color video during the day. When the light level drops below a certain point the security camera automatically switches to IR, or infrared, night vision video. When the light level increases to a specific point the camera automatically switches back to color video.
