So, this sounds like an unfortunate but common issue with the camera when it is mounted on the door. Since the door opens with the gas struts, there is no stop position. I guess the door sometimes opens more, sometimes less.
What do you guys do to make sure the door opens to the same height all the time?
Also, do I need to calibrate the lens and alignment each time or just do the alignment after I have calibrated the lens once if the alignment is off?
