Xiaomi’s new G500 lock combines 3D facial recognition, a 2.3 MP ultra‑wide camera, and multi‑method access in a single unit. Priced at CNY 2,799, it targets Chinese homeowners looking for integrated security and smart‑home control, while offering eight months of battery life and three days of free cloud storage.
What’s new
Xiaomi has rolled out the Smart Door Lock G500 in China, a hybrid device that merges a traditional deadbolt, a video doorbell, and a home‑security camera. The lock’s headline feature is AI‑driven 3D structured‑light facial recognition, which claims to differentiate humans from pets and wildlife with a lower false‑alert rate than earlier 2D solutions. In addition to facial unlock, the G500 houses a fingerprint scanner, 2.3 MP camera with a 160° ultra‑wide field of view, and a suite of secondary entry methods:
- Permanent and temporary numeric passcodes
- Bluetooth proximity unlock
- NFC tap unlock
- Manual key backup
The lock’s exterior includes a built‑in display on the inner side, letting residents view the live video feed without reaching for a phone. The feed can also be cast to any Xiaomi‑compatible smart display or TV via HyperOS Connect, Xiaomi’s latest smart‑home hub protocol.
How it stacks up
| Feature | Xiaomi G500 | Typical mid‑range smart lock (e.g., August Wi‑Fi, Yale Assure) |
|---|---|---|
| Facial unlock | 3D structured‑light, AI‑enhanced | 2D image‑based, optional on few models |
| Camera resolution | 2.3 MP, 160° FOV | 1080p (often 1 MP) with narrower view |
| Unlock methods | 10 (face, fingerprint, passcode, Bluetooth, NFC, key, etc.) | 4‑6 (key, code, app, fingerprint) |
| Power source | 5,000 mAh internal pack + 4 AA cells (≈8 months) | 2×AA or 4×AA (≈6‑12 months) |
| Cloud storage | 3 days free, paid upgrades available | Usually paid from day one |
| Noise level | Reduced‑noise motor, claimed <45 dB | 45‑55 dB typical |
| Price (CNY) | 2,799 (~$413) | US$200‑$350 (varies by brand) |
Compared with established competitors, the G500’s facial recognition is the most advanced feature on the market today. Most rivals still rely on 2D image matching, which can be fooled by photos or struggle with low light. The structured‑light projector creates a depth map, making spoofing considerably harder. However, the trade‑off is a higher price point and a larger physical footprint; the lock’s housing is bulkier to accommodate the camera and projector.
Battery strategy also differs. Xiaomi pairs a rechargeable 5,000 mAh pack with four AA cells, offering a hybrid backup that keeps the lock alive even if the internal pack depletes. Traditional locks either use only replaceable AAs or a single internal battery, meaning users must remember to swap cells more often.
Who should consider it
- Homeowners who want an all‑in‑one entry point – If you’re already invested in Xiaomi’s ecosystem (Mi Home app, Smart Displays, or other HyperOS devices), the G500 slots in without extra hubs.
- Families with pets – The AI algorithm’s reduced pet‑alert rate means fewer false notifications when a cat wanders by the door.
- Security‑conscious renters – The lock supports temporary passcodes that can be set to expire after a single use, ideal for Airbnb hosts or short‑term visitors.
- Tech enthusiasts who value video verification – The built‑in camera streams to any compatible screen, turning the front door into a full‑featured video intercom.
Potential buyers should weigh the price against the added convenience. If you already own a separate video doorbell and a smart lock, the G500 may feel redundant. Conversely, for a new build or a first‑time smart‑home upgrade, consolidating three devices into one can simplify wiring and reduce overall cost.
Availability and outlook
Xiaomi lists the G500 at CNY 2,799 (about US$413) on its YouPin marketplace. No official rollout outside China has been announced, and importers have yet to confirm US pricing or certification. Given Xiaomi’s recent pattern of releasing smart‑home gear globally after an initial China‑only launch, a European or North‑American version could appear within the next 6‑12 months, likely with localized cloud services.
For now, the lock remains a China‑only offering, but the specifications set a high bar for future smart‑lock releases worldwide. If Xiaomi’s facial recognition proves reliable in real‑world tests, we may see other manufacturers adopt 3D structured‑light as the new standard for biometric door access.
