Arducam Noir Camera for Raspberry Pi w/ CS Mount Lens LS-2717CS & OV5647 5MP

Yes, the Arducam Noir Camera is fully compatible with all Raspberry Pi models that feature a Camera Serial Interface (CSI) connector, including Raspberry Pi 4 and Raspberry Pi 5. You simply connect the included 15-pin ribbon cable from the camera's CSI port to the Pi's CSI port. Ensure your Raspberry Pi OS has the appropriate camera interface enabled via the `raspi-config` tool under 'Interfacing Options'.

To change the lens, first unscrew the included LS-2717CS lens by rotating it counter-clockwise from the CS mount thread on the camera board. You can then screw in any standard C-mount or CS-mount lens compatible with a 1/4-inch sensor. Ensure the lens is securely fastened but avoid over-tightening. Note that CS-mount lenses have a flange focal distance of 12.5mm, while C-mount lenses have 17.5mm; adapters are available for mixing mounts.

Use the standard Raspberry Pi OS camera software stack. Enable the camera interface via `sudo raspi-config` under 'Interface Options' > 'Legacy Camera' or 'Camera' depending on your OS version. For basic capture, use the `libcamera` commands (`libcamera-still`, `libcamera-vid`) or the legacy `raspistill`/`raspivid` commands if using an older OS. For advanced multi-camera sync using the FREX/STROBE pins, you may need custom firmware or drivers from Arducam's official documentation and GitHub repositories.

Yes, the integral IR filter on the OV5647 sensor enhances its infrared sensitivity, making it suitable for low-light and night-time imaging. For true night vision, you can pair it with an external IR illuminator. The sensor performs well in ambient low-light conditions for security monitoring, but for complete darkness, active IR illumination is required. The manual focus lens allows you to adjust for sharp imaging under various lighting conditions.
