In a significant move to bolster its smart home ecosystem, Xiaomi has just unveiled the Smart Door Lock 4 Pro Dual Camera Edition in China. This launch comes just months after the successful debut of the standard Smart Door Lock 4 Pro, signaling the company's rapid iteration and commitment to refining home security with advanced technology.
This new model isn't just a minor refresh; it’s a substantial upgrade focused on giving homeowners unparalleled visual awareness and peace of mind, directly from their doorstep.
A Multitude of Ways to Enter: Twelve Unlocking Methods
Staying true to the feature-rich nature of its predecessor, the Dual Camera Edition retains an impressive twelve distinct unlocking methods. Whether you're a tech enthusiast or someone who prefers simplicity, there's an option for everyone. The methods include:
- Biometric Access: AI-powered facial recognition, palm vein recognition, and fingerprint scanning for the ultimate in keyless, secure entry.
- Digital and Physical Keys: Support for NFC-enabled devices (like smartphones or cards), Bluetooth connectivity, and custom passcodes.
- Emergency Backup: For peace of mind, a traditional physical keyhole is included to ensure you're never locked out due to a dead battery or technical glitch.
This versatility ensures that every family member, from grandparents to children, can access the home in a way that is most convenient for them.
The Star of the Show: Dual Camera System for Wider Coverage
The most significant upgrade, as the name implies, is the addition of a second camera. While the original 4 Pro featured a capable 2MP camera with a 152-degree field of view, the new model takes surveillance to the next level.
It now boasts a primary 3MP camera with a wider 160-degree FOV, capturing a broader and sharper image of anyone approaching your door. This is complemented by a secondary 2MP camera with a 128-degree FOV, likely positioned to cover the package area or the feet of visitors, effectively eliminating blind spots. This dual-camera setup ensures that from a tall delivery person to a package left on the mat, everything is captured in clear detail.

See Who's Outside, From the Inside
Security isn't just about keeping people out; it's about knowing who's there before you open the door. The internal half of the Smart Door Lock 4 Pro features a generous 3.97-inch built-in screen. This allows you to visually verify visitors instantly without needing to fumble for your phone or peer through a peephole.
For remote monitoring, the lock supports both Bluetooth and Wi-Fi connectivity. By using the Xiaomi Home app, homeowners can get a live video feed from their doorstep from anywhere in the world. The app also sends instant notifications for doorbell rings, motion detection, and—crucially—any signs of tampering with the lock itself.
Extended Battery Life and Pricing
All these new features require power, and Xiaomi has addressed this proactively. The Dual Camera Edition comes with a larger power pack, featuring a 6,870 mAh lithium battery backed by four AA alkaline batteries. This robust system is rated to last for up to six months on a single charge under normal usage, minimizing maintenance hassles.
With these premium upgrades comes a premium price. The new Xiaomi Smart Door Lock 4 Pro Dual Camera Edition retails for CNY 2,899 (approximately $408), which is about CNY 400 more than the standard model.

Global Availability: What About the West?
For now, this launch is confined to the Chinese market. In regions like Europe, Xiaomi currently sells products like the Smart Doorbell 3S but has yet to release a full smart lock. However, industry watchers suggest that a global version, potentially under a different name like a "Self-Install Smart Lock," could be on the horizon for international markets.
The question remains: will Xiaomi's powerful, feature-packed smart locks soon become a common sight on doors outside of China? If this new Dual Camera Edition is any indication, the global smart home market has a lot to look forward to.
