Operation is pretty imaginable, a guest arrives, rings your door bell and a push notification on your phone lets you know there's a visitor. You can then view, talk and listen through your smart phone should you decide to answer. The visitor can not tell if you are answering from inside the home or remotely, greatly reducing risk of a break in.
