Motor rotate doesn't not cause any sound (just normal motor sound) and I don't use motion tracking. Use only still recording. Will provide video shooting at the camera later.

Dear Andrew, thank you for contacting. Video received, too. Could you please shoot the video at the camera for us? We are not sure if the sound comes from which camera motion: motor rotate, nothing ?
Does hardware reset and re-installation help it?
Thank you
