Video doorbells have been around for some time. They make it easier to see who is knocking on your door. Peeple takes the idea to another level by allowing you to monitor your door from your smartphone. It is a small camera that mounts on your existing peephole, allowing you to see through it on your phone. This WiFi connected device notifies you when someone knocks or opens the door.
Peeple lets you track all your knocks and door opens. The device is easy to install and remove. The companion app runs on your iOS or Android device. Yet another interesting Kickstarter project.
