Smart Video Doorbell
A video doorbell is a doorbell connected to the Internet that alerts the owner's smartphone (or other electronic device) when someone is at the door. The doorbell supports real-time, high-quality video calls, and allows two-way communication. It also allows visitors to be tracked by taking automatic and manual snapshots of the guest and provides constant monitoring of the door.
