When a visitor comes at the door, a smart doorbell sends an alert to the homeowner's smartphone or other electronic device. When a visitor hits the doorbell's button, or when the doorbell's built-in motion sensors detect a visitor, it activates.

Using the doorbell's built-in high-definition infrared camera and microphone, the homeowner may utilize a smartphone app to view and chat with the visitor. They can run on batteries or be connected. Some smart doorbells additionally have a smart lock that may be used to unlock the door remotely.
