Video Doorbell
This goes one step further than the door opener, and allows you to see who is at your door through a video camera that is attached to the door bell. This is a great way to add security to your home, as you only have to let in people that you trust. But there is also the added bonus of a remote control that you can use to unlock the door without ever having to leave your seat.
