The IR-CUT dual-filter switcher consists of a filter (an infrared cut-off or absorption filter and a spectral filter) and a power part (which can be an electromagnetic, motor or other power source). There are two windows in IR-CUT, one is low-pass filter and the other is transparent glass, which can move left and right as needed, so that the color is not distorted during the day, and the night vision function still exists. Simply put, through IR-CUT, only 760 or less wavelength light is allowed to enter during the day, avoiding the color distortion during the day. In the evening, only the infrared light of 760 nm or above is allowed to enter, avoiding the interference of visible light of 760 nm or above 780 nm to infrared light, so the best visual effect can be achieved in the daytime and night.
