5MP OV5647 Fisheye Lens Camera Module for Raspberry Pi

Connect the 15-pin FFC ribbon cable from the camera module to the dedicated Camera Serial Interface (CSI) port on your Raspberry Pi board. Ensure the cable's conductive traces face away from the Ethernet port. Enable the camera interface via `sudo raspi-config` under Interfacing Options, then reboot. Test using `raspistill -o test.webp`.

Yes, the lens barrel can be rotated manually to adjust focus. For close-up subjects, rotate the lens clockwise; for distant scenes, rotate counter-clockwise. Perform adjustments while the camera is live-streaming to a monitor for real-time feedback on sharpness. Avoid excessive force to prevent damage to the threading.

Use the standard Raspberry Pi Camera Module V1 libraries, as this module uses the same OV5647 sensor. The `picamera` Python library is fully compatible. For OpenCV, enable the CSI interface and use `cv2.VideoCapture(0)` with the GStreamer backend. For low-level control, `raspistill` and `raspivid` commands work directly from the terminal.

The OV5647 sensor includes a night vision mode that enhances sensitivity in low-light conditions. Enable it via sensor registers through I²C commands or within your application code. For optimal results, ensure the scene has some ambient infrared (IR) light, as the sensor is sensitive to the near-IR spectrum, though it lacks built-in IR LEDs.
