Xiaomi Smart doorbell is likely to offer high-definition video quality, allowing you to see and monitor visitors in clear detail through the connected smartphone app. The doorbell might be equipped with motion sensors that can detect movement in its field of view. This can trigger notifications to your smartphone, alerting you to any activity outside your door. To maintain visibility even in low-light conditions, the doorbell might include infrared night vision capabilities, allowing you to see visitors or any activity during the nighttime. It's possible that the doorbell supports both cloud storage and local storage options for recording and storing video footage of visitors. This way, you can review footage at a later time. The doorbell might be controllable through a dedicated smartphone app provided by Xiaomi. This app could allow you to receive notifications, access live video feeds, and manage settings remotely. Given that the doorbell is installed outside, it may be designed to withstand various weather conditions, ensuring its durability and functionality over time. The doorbell might allow you to customize motion detection sensitivity and notification preferences to suit your specific needs.
