Let me see if I can clarify… Since you have set up local recording to the mSD card, it will be recording all the time, whether or not you have the Wyze app open on your phone. In fact, your phone could be totally shut off. You do NOT need to press the record button. When you want to view the recording saved on the mSD card, you press the green View Playback button on the Live Stream view of the camera. You will see a timeline appear below the video frame. You can scroll this timeline to view different time periods and you can pinch-out the timeline to zoom in the time scale for finer control.
When you press the record button, you are telling the app to save what you’re seeing on the screen to your phone’s local camera roll. That can be the live stream or the playback stream. Again, it’s not necessary to do this because the video is being saved to the camera’s mSD card all the time. Now, if you want to save a portion of the Live Stream or of the mSD card video to your phone’s camera roll, then you can hit the record button. This will save in real time whatever you’re seeing in the video frame to the phone’s camera roll. For this, the app must remain in the foreground.
Pressing Record is one way to transfer (in real time) video from the camera’s mSD card to the phone’s local storage (camera roll). The other way to save the recorded video is to remove the card from the camera and transfer it directly to a computer.
Since you’ve been pressing Record to save video, you might want to go to the Wyze album on your phone and clean it out. You may have a bunch of space taken up there with video you’ve recorded to the phone.
