So you want to have an easier time seeing who is at your front door? Peeple can help. It is a smart camera that acts as a caller ID for your front door. It mounts on your existing peephole and connects to your WiFi network to send you notifications when someone knocks or opens your door. You don’t even have to be home to get notifications on your iOS/Android device.
Peeple lets you keep track of all your knocks. It lets you look through the peephole from anywhere. Peeple can be installed or removed easily. You can find out more on Kickstarter.
