The AlphaEntry app is a voice and video tie in that can be used by residents of buildings that have the AlphaEntry hardware at their entry.
This app lets you see live video of who is calling you before you answer the call. When a visitor to your building calls you from the AlphaEntry hardware in your lobby you will get a notification on your phone. You then have the option to answer or ignore the call. You can also easily unlock the door from the app to let your visitor in the building.
