I'm wondering if it is possible to remove the lens on the camera board?
Removing the lens is possible, it's attached to the PCB with 2 screws. Or you can remove only the lens from the holder by unscrewing it.
If the lens is removed and put back on the accuracy of the system…
If the lens is removed and put back on the accuracy of the system will be affected since there will be a slight variation compared to the original position.
