If the communication between the Mevo mobile app and the Mevo camera is interrupted (e.g. mobile device battery completely drains), by default your recording and stream will continue at a wide shot until you can reconnect your device to the camera.
If you prefer that the recording or stream stay on the shot you have set rather that go to a wide shot, navigate to Settings and tap General.
There is an Auto-wide on App disconnect option. Toggle the switch to off.
Now Mevo will stay focused on the shot you set until you reconnect the app to the camera.
Please note that if you are streaming and you lose your internet connection entirely, your stream will also stop.
