Do you have the mydlink lite smartphone app? That's the most convenient, as you can change the setting just before you arrive and after you leave. From the live view, touch the 3 dots at the upper right, go to settings, and there's a motion detection on/off setting there. But this setting is only supported through the phone app on some camera models. I know DCS-942L, DCS-2310L, DCS-2332L have it, DCS-930L does not.
