@joseph_1979 It's not a firmware issue. I have hundreds of these cameras and have already sent 2 back. Getting ready to send back 5 more. The issue is the gears are ABS and very small so the teeth break easily. I took one apart to see what was actually going on with them. IMO they need to use either nylon or brass for the focus gears. ABS/ASA are not sturdy enough to withstand the torque of the stepper given the incredibly small surface area. That being said, overall I love this camera. I have only had 8 out of more than 200 fail which says a lot. I think the last 5 were probably just a bad batch since they were all from the same order. Hopefully, someone from @reolink-com_183670189228215 can tell me if this issue has been corrected in the pro models before I place my next order.
