You will be notified through the Altro Smart mobile app, installed on your phone, every time someone is at the front door. It will even take a photo of everyone at your door, so you can always know who has visited.  The types of notifications you will receive are: When you have an incoming video call When your door has been locked or unlocked Access sharing – when you create, edit, or delete an access key When your motion sensor has been activated, accompanied by a 5 second video clip Status updates When you have missed a call or visitor
