Raspberry Pi Camera Module 3 NoIR - 12MP Autofocus

The NoIR variant lacks an infrared cut filter, making it sensitive to infrared light. This enables it to capture images in complete darkness when used with an external IR illuminator, which is crucial for night vision, surveillance, or scientific applications requiring IR imaging.

The Camera Module 3 NoIR is compatible with all models of Raspberry Pi. However, users connecting it to Raspberry Pi Zero models will require a specialized camera adapter cable to ensure proper physical and electrical connection to the smaller CSI connector.

Yes, the Camera Module 3 NoIR features Phase Detection Autofocus (PDAF). This advanced autofocus system quickly and accurately adjusts the lens focus by analyzing phase differences in light passing through different parts of the lens, ensuring sharp images even with moving subjects.

The recommended software library for the Raspberry Pi Camera Module 3, including the NoIR variant, is Picamera2. This powerful Python library provides comprehensive control over the camera's features, including resolution, frame rate, exposure, and autofocus settings, ideal for embedded vision development.

The Camera Module 3 NoIR features a 12-megapixel Sony IMX708 back-illuminated and stacked CMOS sensor. It captures images at a resolution of 4608 × 2592 pixels, offering high detail for various imaging tasks, alongside improved low-light sensitivity.
