A video doorbell is a doorbell that includes a camera and allows homeowners to see and communicate with visitors at their door through a smartphone or tablet. It works by using a built-in camera to capture video footage of the area in front of the door and send it to the homeowner's device. Many video doorbells also include two-way audio, allowing people to speak with visitors remotely.
