IRIS detects light intensity through sensors inside the camera. Based on calculations, the system determines how much the aperture needs to be opened. This system controls the engine in the IRIS lens to dynamically and precisely control the aperture size. This can achieve the best photo effect.
This product is a dual-drive integrated (IRIS & IR-CUT) IRIS: two blades, one blade is blue glass, the other blade is AR glass, they are connected with IR-cut through the carrier, which can realize different filter modes. The engine is connected via FPC and Hall sensors, which can dynamically and accurately adjust the aperture size.
P-IRIS controls the aperture size dynamically and precisely by controlling the stepper motors in the P-IRIS lens. Its main task with DC-IRIS is to continuously adjust the aperture size. The main task of P-IRIS is to set the best aperture position, which is convenient to use most of the center of the lens and the part with the best effect. In addition, the optical error of this position is very large. To improve image quality. P-IrIS requires the use of gain and exposure time to manage small changes in light to further optimize image quality, maintaining the optimal aperture position for as long as possible. If, when the ability to adjust gain and exposure time is exceeded, P-IRIS will adjust the iris to a different position. This product is a dual-drive integrated (IRIS & IR-CUT) IRIS: two blades, FPC connection (including HALL) IR-CUT: one switch board, one blue glass, one AR glass, FPC connection.

1. Q: What is IR-CUT?
A: IR-CUT is simply understood as the "glasses" of CMOS, including "glasses" and "glasses remover", "glasses" is a filter, "glasses remover" is the mechanical structure of IR-CUT.
In general, the lens has two pieces of glass and a bracket, one is used to filter infrared light during the day, and the other is used for full light transmission at night. The two lenses are controlled by an IR-CUT motor (or other type of engine), and they work in turns. During the day, an infrared filter is used to prevent the image from being skewed. At night, full transparency is used to increase sensitivity. IR=Infrared=Infrared
CUT = filter, subtract
2. Q: When to use IR-CUT?
Answer: IPC network cameras generally have high requirements for images. During the day, the image is required to be unbiased. At night, the infrared light has a good night vision effect, and IR-CUT is required.
3. Question: What are the special requirements for using IR-CUT?
A: When using IR-CUT with infrared light, a synchronization signal must be output from the light board to the CMOS board to "tell" the CMOS board whether the current infrared light is on or off. Required for all CMOS with IR lamps with IR-CUT.
