We are really sorry for all the inconvenience.
For the sensitivity of motion detection, we do know that it will not show on the sensitive list as we have explained you before that the sensitivity only shows on the top of the frame of the alarm area that you have picked from the image. We are sorry for this bug.
For the motion detection recording, the alarm area need to be picked first like the above.
And the alarm videos will be saved to your computer if there is no SD card.
While, if you do have a SD card, it will be saved to SD card automatically.
