I am going to buy an E1 camera. What is the behavior of the app when motion is detected?

- the app immediately downloads the video to the phone.
- the application sends only a notification, the video is downloaded from the SD card only when the user starts playback.

I ask because I'm wondering how the app will behave when the camera manages to capture motion but then gets damaged.

Is the cloud required in such a situation, or the application will immediately download the video from the camera to the smartphone (assuming it is on and there was enough time)?
