Xiaomi Smart Door Lock 4 Pro: The Future of Home Security is Here

Remember movies where the main character places their palm on a scanner and the door opens elegantly? Xiaomi Smart Door Lock 4 Pro brings this technology too your door. And it’s not just a marketing trick – this lock truly scans the venous system in your palm using infrared sensors. It’s essentially the same technology some banks use to secure vaults.

The new smart lock by Xiaomi has just launched in the Chinese market at a price of 2,499 yuan (approximately $345 USD or 7,300 CZK). While not inexpensive, the price becomes justifiable when considering the features. Beyond the futuristic scanner, you also get 3D facial recognition, a camera with night vision, and seamless connection with the entire Xiaomi ecosystem.

Twelve Ways to Get home

Smart Door Lock 4 Pro offers a total of 12 different unlocking methods. In addition to the aforementioned scanner and 3D facial recognition, you have a classic fingerprint reader, a numeric keypad for a PIN, an NFC card reader or phone, and, of course, the ability to unlock the door remotely via the request.

Xiaomi hasn’t forgotten the classic mechanical key. So, if you run out of batteries, you’ll always have a reliable backup. The lock also features a built-in AI algorithm that learns user habits and can detect potential security threats. It sends real-time alerts to your smartphone if suspicious activity is detected, such as repeated incorrect passcode attempts or forced entry.
