I just picked up two v2 and two pan cams to test before replacing about 30 foscam camera in four locations and I have some suggestions that would help seal the deal for me. Overall these things are amazing!
1 - notifications for sound/motion - add a way in the app to tell if I have already played it or not
2 - ability to enable push notifications by user. I shared the cameras with my wife (separate accounts) and she hates getting the alerts and I like them, but if I want to keep the cameras I can’t send her push notifications.
3 - full screen inconsistency - the playback screen has a different location and icon for viewing in full screen than the notification page does. It makes it a little confusing sometimes.
4 - multi camera live view - ability to see a live view for multiple cameras on the same screen even if it is SD or lower, if that is not feasible a way to update the thumbnails on launch automatically would be nice.
5 - widgets/shortcuts - ability to quickly pull up a specific camera from the home screen. For example with other ip camera viewer apps I can create a shortcut for the camera in the babies room and another for the front door and open these quickly when I know exactly what I want to look at instead of having to load the full list.
