The Xiaomi video doorbell features a diagonal 180° ultra-wide view with a 107° vertical angle to monitor the entire area in front of the door. It captures 2K resolution video for clearer facial details than 1080P and includes six 940nm high-power infrared illuminators with adjustable night vision sensitivity for reliable low-light imaging. The device is IP65 rated for water and dust resistance and supports both a 5200 mAh lithium battery and hardwired power. Built-in theft prevention measures, 24-hour motion detection with AI human-shape recognition, and free rolling 72-hour cloud storage provide continuous and secure monitoring.

Advantages

Ultra-wide 180° diagonal view and increased vertical angle ensure panoramic coverage of the doorstep area. Higher 2K resolution records more detail than 1080P for better identification. The adjustable night vision and six infrared illuminators enable clear images in low or no light. IP65 protection allows stable outdoor use in adverse weather. Dual power modes and a high-capacity 5200 mAh battery reduce the need for frequent charging. Security features include forced-removal alarm, screw and adhesive mounting, device pairing, and an onboard security chip to protect privacy. Smart motion detection with AI reduces false alerts, and free 72-hour cloud storage lets you review recent events without extra subscription fees.

How to use

Install the doorbell at the recommended height and secure it with the included screws and adhesive according to the mounting instructions. Choose either the built-in 5200 mAh lithium battery for wireless operation or connect the unit to mains power for continuous supply. Use the companion smartphone app to configure Wi‑Fi connection, adjust night vision sensitivity, define a custom monitoring area, enable AI human-shape detection, and set up notifications. Test two-way audio, personalized auto-reply messages, and the indoor wireless chime volume. When the device detects forced removal or abnormal motion, it will record video, trigger an alarm, and send a notification to your phone.

Recommendations

For reliable outdoor performance, mount the doorbell under a small overhang if possible to reduce direct exposure to heavy rain. Regularly check the app to confirm firmware updates and review the 72-hour cloud footage; if you prefer continuous power, use the hardwired option to avoid battery recharge intervals.
