Arlo Video Doorbell is designed to capture what traditional video doorbells can't. See the person that is at your door from head to toe or the package on the ground with the 180-degree diagonal viewing angle. The Arlo Video Doorbell doesn’t just notify you only when someone’s pressed it. In fact, it can sense motion, so it sends a notification to your phone when it detects movement. If you’re worried about a package being stolen or suspicious characters in your neighborhood, this device can help you feel a bit safer. It also has a built-in siren that you can trigger or set it to sound automatically.
