A Smart Doorbell is a modern device that combines a traditional doorbell with advanced technology. It typically features a camera, microphone, and speaker, allowing homeowners to see and communicate with visitors remotely through their smartphones or tablets. This enhances security by enabling users to monitor their front door from anywhere. Many Smart Doorbells also include motion detection and night vision capabilities, alerting homeowners when someone approaches their door. Some models can integrate with other smart home devices, such as smart locks and home security systems, providing a comprehensive solution for home monitoring and safety.
