Hi Sascha
1. Yes, the Raspberry pi4 doesn’t have a LED enable pin on the camera port to drive the IR-cut. So you have to connect the IR switch signal manually from the camera board to Raspberry pi’s GPIO.
2. If the lens is screw all the way into the lens holder, it will stuck the IR-cut mechanism. So you have to fine tune the lens to get both in focus and not stuck the IR-cut filter.
Let me know if you need more help.
