Xiaomi launched the Smart Door Lock 2 Face Recognition Edition in mainland China on July 16, 2024, with an introductory price of 1,899 yuan and a reported standard price of 1,999 yuan. The often-quoted $262 is only an approximate conversion of the launch price, not a U.S. retail price. The model adds 3D face recognition and a door camera to Xiaomi’s Smart Door Lock 2 platform; overseas availability and installation support are not established.
What Xiaomi released and what it cost
The Chinese product name is 小米智能门锁 2 人脸识别版, commonly rendered in English as Xiaomi Smart Door Lock 2 Face Recognition Edition. It is a face-recognition variant of the Smart Door Lock 2, rather than a wholly separate product family. Launch reports describe it as retaining the platform’s general design while adding AI 3D structured-light facial recognition. MyDrivers’ launch coverage describes that design relationship.
Xiaomi announced pre-sales on July 9, 2024, at a reported standard price of 1,999 yuan and introductory price of 1,899 yuan. General sale began July 16, 2024, at 10:00 local time in China, according to ITHome’s pre-sale report and its launch-day report. The 1,899-yuan figure is historical launch pricing, not a verified current price. Xiaomi’s China-store product page does not establish a U.S. price or international retail availability.
At launch, 1,899 yuan converted to roughly $261–$262 depending on the exchange rate. That conversion excludes shipping, taxes, import costs, installation, and any warranty differences; it should not be read as an official dollar MSRP.

How the 3D face recognition is described
The lock uses structured light to capture depth information, rather than relying only on a flat image. Xiaomi’s reported feature set includes liveness or anti-spoofing detection and touch-free unlocking. Launch coverage gives a user-height coverage range of approximately 1.2–2 meters and a recommended recognition distance of approximately 0.4–0.8 meters. These are reported specifications, not independently tested accuracy results. ITHome’s launch report lists the ranges and feature claims.
The lock reportedly enters a default 15-second sleep period for face recognition after the user activates a leave-home state. This is intended to reduce unwanted recognition after the door has closed. The available launch information does not establish performance with face coverings, heavy sunglasses, strong backlighting, children, identical twins, or substantial appearance changes. Dirt or obstruction over the recognition hardware, poor mounting height, and standing outside the recommended distance are practical reasons to use another method.
Unlocking methods and fallback options
Launch reports describe ten unlocking categories, but several depend on optional accessories or Xiaomi devices. The list is not ten separate biometric systems, and it does not state how many credentials the lock can store.

| Method | Details |
|---|---|
| Face recognition | 3D structured-light recognition; Xiaomi-reported feature |
| Fingerprint | Built-in fingerprint unlocking |
| Password | Fixed, periodic, temporary, and virtual/decoy password types are reported |
| Bluetooth | Listed as an unlocking category; precise offline behavior is not established |
| Emergency key | Mechanical backup key |
| NFC card | Optional |
| Xiaomi phone, watch, or band | Optional device-based unlocking |
For day-to-day use, configure more than one local fallback rather than assuming facial recognition will always work. A fingerprint, password, and emergency key provide alternatives if recognition is obstructed or enrollment is unsuccessful. Keep the emergency key somewhere outside the home, and confirm the exact optional accessories and supported devices before purchasing.
Camera, alerts, and Xiaomi smart-home scenes
The built-in smart peephole camera is reported to have a 2.3-megapixel sensor and a 160-degree field of view, with AI person detection, remote viewing, notifications, and three days of rolling cloud storage. The three-day figure comes from launch reporting; it does not establish whether storage is continuous or event-based, permanently included, subscription-free, or available in every account region.
The lock is described as supporting Xiaomi’s Mijia/Mi Home app and HyperOS Connect ecosystem. Reported automation examples include switching on lights on arrival, closing curtains, turning off devices when leaving, or opening a camera scene. The reports do not verify Matter, Apple Home, Google Home, or Amazon Alexa support.

Wi-Fi and Bluetooth are listed, and launch coverage says a separate Bluetooth gateway is unnecessary. Remote alerts, camera viewing, cloud history, and smart-home scenes depend on network and service availability. Local authentication may continue through an internet outage, but the reports do not document every offline behavior. They support remote monitoring and alerts, not an unqualified claim that the door can be remotely unlocked.

Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Before relying on camera or biometric features, check Xiaomi’s privacy terms for the relevant account region and determine how video retention, cloud access, and biometric data are handled. Available launch coverage does not establish where face templates are stored, whether recordings are encrypted, whether local storage exists, whether the camera can be disabled independently, or what happens to remote features without Wi-Fi.
Lock hardware, security claims, and power
Xiaomi’s reported hardware includes a fully automatic, noise-reduced lock body that retracts the latch after successful authentication, internal sensors for abnormal lock-state detection, and a direct-insert C-grade lock cylinder running through the body. “C-grade” is a Chinese cylinder classification, not a universal burglary-resistance rating. These are product claims, not independent certification or testing; they do not prove the lock is safer than every mechanical lock or resistant to all forced entry.

The reported power system combines an integrated 5,000-mAh lithium battery with backup dry cells and USB-C emergency power from a power bank. The launch report does not confirm the backup-cell count, exact emergency-input rating, battery life, or whether backup cells engage automatically. Follow the lock’s manual for those operating details, heed low-battery warnings, and keep a charged power bank available. If the batteries are exhausted, the emergency key is the mechanical fallback; confirm the installed model’s procedure rather than assuming all backup modes behave alike.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Check the door and installation before buying
A smart lock is not a universal drop-in replacement. The launch reports do not provide enough installation dimensions or a global installation policy to confirm fit for a particular door. Have a qualified installer check the existing mortise and lock-body dimensions, door thickness, opening direction, strike alignment, handle clearance, and the material and construction of the door. Compatibility is especially important for narrow, unusually constructed, or security-rated doors.

- Confirm whether the existing mortise and lock body match the lock’s requirements.
- Check clearances for both exterior and interior panels and for the automatic latch.
- Ask whether installation requires a Xiaomi-authorized technician and whether that service exists in your location.
- If you rent, verify that you may modify the door; check any applicable fire-rating or insurance requirements.
Do not treat an imported listing as proof of installation support, warranty coverage, or compatibility. Xiaomi’s product page is a China-store listing. Buyers outside mainland China should confirm the exact model, account and app region, firmware access, accessories, local service, and return terms with the seller and installer before paying.

Who should consider this model?
The strongest fit is a household already using Xiaomi or Mijia devices in a market where the lock can be installed and supported, and where hands-free entry, multiple authentication methods, and an integrated camera are useful. Its practical appeal rests as much on the door camera and ecosystem automations as on face recognition.
It is a weaker choice for renters unable to alter a door, privacy-sensitive households unwilling to use facial biometrics or cloud-connected video, buyers requiring confirmed Matter or major third-party smart-home support, or anyone who needs local installation and warranty coverage that has not been verified. For a China-market import, door compatibility and regional account support are purchase prerequisites, not afterthoughts.
For launch context, Gizmochina’s English-language launch summary also covers the July 2024 release. Xiaomi’s global automatic smart door lock page is for another model and should not be taken as evidence that this Face Recognition Edition is globally sold or supported.
