Xiaomi Smart Doorbell 3S
Remote monitoring for peace of mind at home

Head to toe with the diagonal 180° ultra-wide view
The new-generation ultra-wide camera increases the vertical angle to 107°, to ensure clear, panoramic monitoring of the entire area in front of the door.
*When the doorbell is installed at a height of 1.5 meters, it can capture full-body footage of visitors 1.1 meters away from it.

Ultra-clear vision with 2K resolution, clearer than 1080P
2K resolution images are higher quality and record more details than 1080P images, allowing you to see visitors' faces more clearly.

Superior night vision: See clearly in low or no light
The new night vision sensitivity adjustment function can help avoid inaccurate night vision switching. The 6 built-in 940nm high-power infrared illuminators are activated automatically when it turns dark. You can see clearly even in low or no light.

Professional IP65 water and dust resistant design
No fear of adverse weather conditions
The IP65 water and dust resistance rating enables stable performance in adverse weather conditions.

Supports both a lithium battery and hardwired power supply
Two power supply modes are supported. You can choose either a lithium battery or hardwired power supply according to your needs.
*The hardwired power supply mode is only applicable to houses with a doorbell wire reserved at the door. The power supply requirements are as follows: 8-24VAC, 10-40VA.

Ultra-high capacity lithium battery Only needs charging 3 times a year
The built-in 5200mAh high-capacity lithium battery makes frequent charging and battery replacement unnecessary. The Type-C charging port enables faster and easier charging.
*Battery life and battery data are from the MadV laboratory. The standard capacity of the battery is 5200mAh. Under laboratory conditions, the doorbell was usable for 4.2 months in standard mode, at normal temperature (25°C) and pressure, with 20 10-second videos taken every day and no other operations used. Battery life and capacity may vary slightly due to individual product differences, service environment, and other factors.

Multiple theft prevention features Fully encrypted to protect your privacy
Forced removal alarm + powerful 3M adhesive + screw fixing + strong doorbell and user account pairing.
When the doorbell detects that it is being removed, it will trigger an alarm, record video, and send a notification to your phone. Equipped with the Xiaomi Security Chip, the doorbell can fundamentally prevent privacy leakage caused by video streaming, device forgery, etc.
*The doorbell and user account are paired one-to-one in the cloud. Even if the doorbell is forcibly removed and stolen, no one can pair with or use your doorbell.

24-hour smart motion detection Automatic video recording of abnormal motion on the doorstep and notifications sent to your smartphone
Equipped with a human body sensor and AI human shape detection technology for all-day monitoring of abnormal movement. Any abnormal motion on the doorstep is immediately recorded and sent to your smartphone.
*Video recording is only activated when a human body is detected.

New customizable monitoring area
You can customize the monitoring area as needed to receive only the notifications you care about.

Free, rolling 72-hour cloud storage
Watch videos recorded in the last 72 hours for free without purchasing a microSD card or subscribing to cloud services, and check recordings of abnormal doorstep movement anytime, anywhere.
*72-hour rolling cloud storage means that the camera records videos on a rolling basis. Each video will be stored on the cloud for 3 days and be deleted after that.

Supports Alexa & Google Voice Assistant
Voice control works with Amazon Alexa or Google Assistant.

Real-time remote monitoring - A doorbell that's also a monitor
Two-way audio communication with visitors via your smartphone anytime, anywhere. Supports remote doorbell wake-up to check abnormal movement by the door.

Supports personalized settings and customizable auto-replies
Record a fun welcome message that will automatically play when visitors press the doorbell.

The wireless chime rings even when disconnected from the internet
With 4 volume settings to choose from, the dedicated high-volume indoor chime can be heard clearly in noisy environments. The "Do not disturb" mode mutes the chime when you don't want to be interrupted.
