Introducing Night Vision Cameras: In highly developed urban landscapes, many locations and scenarios that require round-the-clock monitoring cannot provide continuous lighting. This not only leads to a waste of resources but also to light pollution. Similarly, in unexplored nature, many organisms only become active at night and the presence of artificial lighting can significantly disrupt their natural rhythms. This is where night vision cameras play a key role.

OHWOAI Surveillance mainly uses infrared night vision cameras, utilizing infrared technology to achieve the "night vision" function.

How night vision cameras work: Generally, night vision security cameras with infrared technology work by projecting infrared light onto objects in dark environments where there is no visible light or very little ambient light, which then reflects off the object and enters the camera lens to form an image.

An infrared camera illuminates a subject by emitting infrared light, which is then received by a security camera to form a video image. The concept can be likened to using a flashlight in the dark: the flashlight acts as a source of infrared light, and the camera acts like the human eye. The resulting image is made up of reflected infrared light rather than visible light, making it possible to record scenes in dark environments that are invisible to the naked eye.

Importance and Applications of Night Vision Cameras: The LED lights of infrared cameras play a vital role in providing clear surveillance footage in environments with little or no lighting. This type of light is invisible to the human eye, so it can be recorded without the subject's knowledge. Infrared light is a type of radiation that cannot be detected by the naked eye.

The physical principle of infrared night vision is based on the fact that objects with a temperature difference transfer heat from a higher temperature to a lower temperature. This transfer mainly occurs through infrared radiation. Hotter objects emit infrared radiation that is not detectable by the naked eye. However, the image sensor (CCD or CMOS) of a security camera is able to receive this radiation and convert it into an electrical signal that can be processed into a visible image.
