Access control
With a video phone at your front door, your touchscreen (if you have one) or your smartphone/tablet will show you who is at the door.
In this way, you can keep an eye on guests and decide who is allowed in, even when you're not at home.
An eye on who's at the front door
See who's at your front door and communicate with them, even from a distance, with your smartphone. And if you have an electronic lock installed, you can open your door from a distance.
You can even take a peek outside to see what's going on.
