When you set up recording to the microSD card (Settings > Advanced Settings > Local Storage) in Event Only mode, the camera will save each one minute video segment that contains any motion with no limitations. This will occur up to the point that the card is full at which point the oldest video will be deleted in favor of the new. This is independent of the 12s cloud alert clips, which don’t even need to be enabled for SD card recording to occur.
So again, tap the gear icon in the live stream view, then Advanced Settings > Local Storage. Turn on the switch and select “Record events only”. Every 1-minute segment that contains motion will be saved, and only those segments. View it by tapping View Playback from the live stream. The timeline will be shaded green where video was saved and you can use the left/right arrow buttons to move back and forward among segments.
