Although there is a large selection of smart locks from both Aqara and Xiaomi, many with HomeKit compatibility these days, it does not prevent the latter company of the two from showing yet another smart lock, this time called Smart door lock X. What makes this lock different, you may ask, and the answer would be that the latest ‘lock on the block’ comes with built-in face recognition technology. However, before you get too excited, from all the information we have seen so far, this particular aspect of the lock is not exposed to HomeKit, even if the lock itself is. It probably will not deter some as the feature will still help unlock the door no matter what app you are mainly using.

The lock itself, which like just about all locks from Xiaomi, is designed for doors that have mechanical parts of the mortice, as opposed to the simple deadbolt design found in the United States. This means that the lock is almost certainly only intended for Chinese customers, at least officially.

The new model has many methods for unlocking the door, which include the aforementioned face recognition, fingerprint, password, NFC as well as app control via Mi Home and HomeKit and standard keys. The lock has a dedicated chip for storing face recognition data locally and not in the cloud. A special ’20 digit virtual password ‘feature allows you to press random numbers before and after your own actual code to hide the correct code from anyone who might be monitoring the keyboard input (unlikely as it is). When the camera detects a face, a message is pushed along with a livestream or still image (depending on settings) to your phone.

Back to the face recognition feature, the lock has a series of sensors built into the top of the lock that use them to confirm the person’s identity, in what looks like similar depth-sensing technology used by FaceID on iPhones and iPads. The other sensors include an additional IR LED for dimly lit areas, an RGB-compatible camera lens, a photosensitive sensor, a proximity sensor so it knows when to start identifying a face and a separate infrared camera.

The lock also has a mini-AMOLED display in full color, which among other things shows the status of the lock. For power, the lock uses a rechargeable and replaceable 6250mAh battery pack, which should easily give you six months of life.

There is no word on price yet, but the lock will be officially launched on Tuesday, October 12 in mainland China.

Thanks to Eric Yao for heads up!
