According to different working principles, the current night vision technology can be divided into three categories, namely:
Visible light supplement technology.
That is, ordinary white LEDs are used as fill light sources and have been used in recent years.
Passive infrared night vision technology (also known as thermal imaging night vision technology).
Infrared thermal imaging night vision technology, also known as passive infrared night vision technology, and low-light night vision, thermal imaging work does not require additional light source, is a passive night vision technology. However, it differs from the operation principle of the low-vision night vision device. The low-light night vision device works by enhancing the natural light, and the infrared thermal imager utilizes the temperature difference between the various parts of the scene and the temperature difference between the scene and the background to image, that is, infrared heat. Imaging Dongguan monitoring system is imaged by directly receiving the infrared rays emitted by the target object itself.
Active Infrared Night Vision The active infrared night vision technology uses infrared light with a wavelength of 780 nm to 1100 nm to illuminate the observed scene. The light in this band cannot be recognized by the human eye, but imaging devices such as CCDs can sense the imaging, so as to enhance the night vision effect. The current monitoring installation in Dongguan mainly uses active infrared night vision technology. The article comes from Dongguan Chuangtongbao Communication Technology Co., Ltd.
