Erasing detection area on the app does not seem to work?

I have the same problem. I Could not find a firmware update for RLC-410-5MP. Contacted support and they sent me the link below. Not sue why its so hard to find? I too am having issues with motion sensor. Keeps alerting no matter the settings.
NO way to turn it off? Maybe firmware will help.

So to be clear to turn off motion detection while I'm at home I have to log into cam clear the motion detection area and then when I leave log in and set it up again? Seems a little ridiculous to me.
