You can’t get videos by email.
To get pics/videos to the app:
On the portal, log in, then under MY CAMERAS > MOBILE ACCESS, create and admin code and save.
On the app, Account, +, type the account number and admin code, Save, Done, Authenticate.
Larger version of the pic, when viewing thumbnail, tap HD (just like you tap the little movie camera to request the video). BTW, you must request the video, it doesn’t get sent automatically.
