Not your regular doorbell but a Wi-Fi doorbell that allows you to see, hear and speak to people at the door using your smartphone or tablets.
The Skybell has motion sensors that alert you when you have people at the door and allows you to switch the video camera on with your app. This doorbell is weather-proof so you don't have to worry about exposing this to the elements. With nightvision you don't have to worry about not being able to see someone at the door in the dark. The wide angle camera makes sure you're whole front door area is captured.
