A new smart doorbell devised by a pair of entrepreneurs uses facial recognition to notify who is at the door.

Different light settings can also be set for each person, when used with a smart light bulb.
According to company's co-founder Nezare Chafni, images taken by Chui are added to the Web application, where a database of visitors are logged, and new devices can be connected to the doorbell. New friends can be added, with custom messages and settings.
