Yeah, getting to the reset button can be a pain sometimes and even when you get to it you will have to realign your camera again. I know some have theirs installed very high up, second floor...You can just factory reset by pushing the button or doing it in the camera GUI.
Most here would opt for the button if possible.
Kicks and grins - meaning most here only update IF the release notes say it fixes a problem they have - so if your camera is working properly, don't update it just to be on newer firmware. We have threads every week where an update removes a feature someone was using.
