Raspberry Pi HD Pi NoIR V2 camera board Raspberry Pi HD Pi NoIR camera board connects to any Raspberry Pi or Compute Module to create HD photos and video. The Pi NoIR (without infrared) is the same as the standard camera module but without an infrared filter. Therefore, it is excellent for photography and video in the dark.
The module uses Sony's IMX219PQ image sensor that offers high-speed, high-sensitivity video images.
The Pi NoIR module offers contamination from Reduced image such as fixed pattern noise and smudges. It also has automatic control functions such as exposure control, white balance and luminance detection. Raspberry Pi NoIR Camera Board, Sony IMX219 8 Megapixel Sensor features:
and benefits: No infrared filter
High quality images
