Xiaomi Smart Door Lock M40 Pro: 12 Unlocking Methods and AI for Home Security
The M40 Pro integrates three biometric systems: AI palm recognition, 3D structured light facial recognition, and a fingerprint sensor. The palm system uses infrared light to read veins under the skin, ensuring contactless and secure access. Facial recognition is BCTC-certified at bank level, with active presence detection, while the fingerprint sensor adapts over time thanks to a self-learning algorithm.
The lock is equipped with a panoramic dual-camera electronic eye, with 3MP (175°) and 2MP (128°) sensors, for a 190° overall view. Built-in artificial intelligence detects people, packages, and suspicious movements, and streams images in real time to Xiaomi TVs, smartphones, and even the SU7 car. Inside, a 5-inch HD display allows for direct monitoring.
The M40 Pro supports 12 unlocking modes, including Bluetooth, NFC, codes, physical keys, and remote control via Mi Home. The direct-entry C-grade cylinder and pass-through structure ensure superior physical protection. Dedicated sensors monitor the door status, detecting whether it is ajar, forced, or left open.
The lock is powered by a rechargeable 8.000mAh battery with up to 4,5 months of battery life, and four AA batteries can be used as a backup for another 6 months. It includes internal and external Type-C ports for emergency use and supports reverse wireless charging from compatible smartphones.
On the connectivity front, we find Wi-Fi 6, Bluetooth 5.3, and NFC, with full integration into Xiaomi's HyperOS ecosystem. It's possible to automate lights, air conditioning, and surveillance systems when unlocking. It's also compatible with WeChat for video calls and voice intercom, making two-way communication simple and immediate.
The brushed metal design and refined ergonomics complete a product that combines technology, safety and style.
