A smart doorbell is an internet-connected security device that allows homeowners to see, hear, and speak to visitors at their door through a smartphone app. Equipped with a high-definition camera and motion sensors, it provides real-time video alerts and records activity even if a guest does not ring the bell. Many models feature two-way audio and infrared night vision, ensuring clear communication and visibility regardless of the time of day. By integrating seamlessly into a home automation network, a smart doorbell adds a vital layer of convenience and surveillance that enhances the overall safety of a modern residence.
