6. Operation
6.1. Dual-Camera Dual-Scenario Monitoring
The camera features two lenses, allowing for simultaneous monitoring of two different areas. One lens provides a wide-angle fixed view (2.8mm short-focus), while the pan-tilt lens offers a 6mm telephoto view for flexible detail tracking and AI-driven follow-up.

6.2. Intelligent Full-Color Night Vision
Equipped with eight spotlights (two white lights + two infrared lights), the camera provides intelligent full-color night vision, presenting clear, detailed images even in low-light conditions. When a human figure is detected at night, supplementary lighting will automatically turn on for a full-color image.

6.3. AI Human/Vehicle Detection & Tracking
The camera's local AI algorithm accurately identifies human figures and vehicles. When an abnormal state is detected, the Mi Home App will send out alarm notifications and record videos as evidence. The dual-camera AI collaborative detection enables wide-angle recognition, pan-tilt follow-up, and precise tracking.

7. Maintenance
7.1. MicroSD Card Installation/Removal
The camera supports microSD cards from 16GB to 256GB. A fast, good quality memory card from a reputable manufacturer is recommended due to the high bit rate and recording volume from two cameras.
- Locate the microSD card slot on the camera.
- Carefully insert the microSD card into the slot until it clicks into place.
- After installation or removal, please make sure to properly install the dust cover on top of the card slot to prevent water from entering the product and affecting its normal operation.
7.2. Cleaning
Wipe the camera lens and body with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
7.3. Cloud Platform Calibration
If the cloud platform rotates for a long time, it may shift. It is recommended to calibrate it regularly through the Mi Home App.
8. Troubleshooting
- Connection Issues: Ensure your mobile device's Bluetooth is on during initial setup. Verify that you have selected the "China" server in the Mi Home App.
- No Recording/Storage: The package does not include a microSD card. Users are required to bring their own. Cloud storage is a paid service and needs to be separately activated.
- AI Features Not Working: AI functions such as motion detection, vehicle detection, virtual fence, and face recognition are initially disabled. They can only be used after being enabled in the "AI Functions" section of the Mi Home App.
- Notifications Delayed/Missing: Message push notifications are affected by the alarm time interval set by the security assistant (default 10 minutes). Users can modify these settings in the security assistant.
- Language Display: While the Mi Home App supports your country's language (e.g., English, Russian), some settings or video recording time displays might remain in Chinese, which cannot be changed by setting the time zone.
- Camera Calibration: If the camera's pan-tilt mechanism seems to be over-rotating or making excessive noise during calibration, it's a known characteristic. Regular calibration via the Mi Home App is recommended.
9. User Tips
- Mi Home App Server: Always select the "China" server in the Mi Home App settings for optimal compatibility and functionality with this camera model.
- MicroSD Card: Invest in a high-speed, reputable brand microSD card (128GB-256GB) to handle the high-resolution dual-camera recordings effectively.
- Wired Connection for Stability: If your monitoring area is far from your Wi-Fi router or experiences severe signal interference, consider using a network cable for a more stable and reliable data transmission.
- Power Adapter Placement: Remember the power adapter is not waterproof; ensure it is installed in a dry, indoor location.
- Explore AI Features: Don't forget to manually enable and customize the AI detection features (human/vehicle detection, virtual fence, face recognition) within the Mi Home App to enhance your security monitoring.
