Using this camera is a breeze. First, connect it to your Raspberry Pi. It's compatible with all versions, so you don't have to worry about compatibility issues. If you want to use the night - vision feature, connect it to a 3W infrared lamp. The focus function is really handy. You can turn the adjustment knob to focus on objects at different distances.
When it comes to power, make sure to use an external 3.3V power supply. This will ensure the camera works properly.
For maintenance, keep the camera lens clean. You can use a soft, dry cloth to gently wipe it. Avoid exposing the camera to extreme temperatures or humidity. If you're not using the camera for a long time, store it in a dry and cool place. And don't forget to refer to the RPi Camera User Manual for more detailed information.
