Arducam 5MP OV5647 NoIR Motorized IRcut Camera w/ LS-1820 Lens

First, ensure the Raspberry Pi is powered off. Connect the camera's 15-pin ribbon cable to the CSI port on the Pi, aligning the connector correctly. Enable the camera interface via 'sudo raspi-config' under 'Interface Options'. Reboot, then use commands like 'libcamera-still -o test.webp' or Python's picamera library to capture images. The motorized IR-cut filter operates automatically based on sensor readings; no software configuration is needed for its basic day/night switching function.

Yes, the module features a standard M12x0.5 thread mount, allowing you to unscrew the included LS-1820 lens and attach compatible M12 lenses. You can also use CS-mount lenses with an appropriate M12-to-CS adapter. When changing lenses, ensure the sensor cover glass is clean and avoid touching the imaging sensor directly. The field of view and focus distance will change based on the new lens's focal length and optical characteristics.

The filter contains a small motor that physically slides an IR-blocking glass element in front of the sensor. It is designed to activate automatically based on ambient light levels detected by the camera system, switching to night (IR-pass) mode in darkness. For advanced control, you may need to access the filter's control pins via GPIO, though this typically requires modifying the camera driver or using a dedicated library from Arducam to send specific I2C commands for manual override.

The module operates from a 3.3V to 5V DC supply, drawing current primarily during sensor operation and filter motor actuation. It is designed to be powered through the Raspberry Pi's CSI connector, which supplies 3.3V. There is no need for an external power source under normal use. Ensure your Pi's power supply can deliver adequate current for the entire system, especially if other peripherals are connected, to avoid voltage drops affecting camera stability.
