Maintenance
Charging the Doorbell
The doorbell features a 5100mAh high-capacity battery. When charging is required:
- Use the provided Type-C power cord.
- Insert the disassembly pin into the disassembly hole on the top of the doorbell and press it until the spring inside the hole is pressed to the bottom.

- Connect the Type-C interface to charge the doorbell.
Important:

- Ensure the charging port is in a non-closed state.
- If charging outdoors, ensure waterproofing measures are taken.
Battery Life
The 120-day battery life is an approximate value and can vary based on usage. Factors affecting battery life include:
- Frequency of triggering video recording.
- Detection sensitivity settings.
- Maximum shooting duration.
- Shooting interval.
These settings can be adjusted in the Mi Home app to optimize battery usage for your specific needs.
Cloud Storage Management
Manage your cloud storage through the Mi Home app. While 72 hours of rolling storage is free, consider a cloud storage membership for longer retention of event videos.
Troubleshooting
- Wi-Fi Connectivity Issues: Ensure your Wi-Fi network is 2.4GHz. The doorbell does not support 5GHz networks and requires an active network connection to function.
- App Connection Problems: If the doorbell is not connecting to the Mi Home app, verify that the app's region setting is set to "Chinese Mainland". This doorbell is a Chinese version and is not compatible with the Global Version of the app.
- Dismantling Alarm Not Functioning: The dismantling alarm function is turned off by default. You must manually enable it within the Mi Home app settings if you wish to use it.
- Short Recording Duration: The actual recording duration of videos depends on the set recording limit time and whether continuous activity is detected within the frame. Adjust settings in the Mi Home app if needed.
- No Humanoid Detection Notifications: Ensure humanoid detection is enabled and configured in the Mi Home app. After a human figure appears on screen, the system should automatically send a reminder to your phone and upload the event video to the cloud.
- Adhesion Issues: If using adhesive for installation, ensure you wait 24 hours after initial placement for optimal adhesion.
User Tips
- Optimal Installation Height: For best detection and viewing angles, install the doorbell at approximately 1.5 meters (about 5 feet) from the ground.
- Wi-Fi Signal Strength: Ensure the doorbell is installed within good range of your 2.4GHz Wi-Fi router for stable connectivity and performance.
- Customize Detection Settings: Adjust the detection sensitivity and recording intervals in the Mi Home app to suit your environment and reduce unnecessary recordings, which can also help conserve battery life.
- Regular Charging: While the battery life is long, establish a routine for checking the battery level via the app and charging the doorbell to ensure continuous operation.
- Explore Mi Home App Features: Familiarize yourself with all the settings and features available in the Mi Home app, such as voice intercom options and smart home integrations, to maximize your doorbell's utility.
