A pair of entrepreneurs have devised a "smart doorbell" that uses facial recognition to notify who is at the door.
The owner of the home is notified of who is at the door via an email and when the Chui doorbell is connected to a Wi-Fi connected door lock, the owner can let the guest in remotely, CBS reported.
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.
