Infrared night vision
Infrared night vision refers to a function in which, in a dark or poorly lit environment, the camera uses an infrared transmitter to actively project infrared light onto an object, and the infrared light is reflected by the object and enters the lens to produce an image. It is also the most common method of night vision.
The range of infrared night vision is usually about 10 meters. Some cameras can increase the range of night vision to 30-50 meters by increasing the transmission power. However, the main problem with infrared night vision is that the image is black and white and cannot show more details.
