before you click on motion tracking on/off make sure you blue marked all the area, them you click the both button on. The recorded motion will mark orange colour on time line view. hope you can understand me. sorry for my bad english.

Yes I understand that but then how do you save the orange motion capture to your device from the timeline?

Now new update already enable email, you can send to email. to do this you must open with web browser at on local network. beside that you can use NAS storage if you have it. to me this only the way to save every detected motions.

Alternatively you can used DU Recorder to record everything on the screen. it works.
