Xiaomi unveils Smart Door Lock 4 Pro, a smart lock that recognises capillaries on hands and detects intruders using AI
Xiaomi has officially presented Smart Door Lock 4 Pro, the flagship model in a new series of door locks. It features a wide-angle HD camera in the peephole and a large screen on the inside, so you can quickly see who's standing at the door without a phone.
Details.
It's a door lock, but it's equipped with the most advanced technology. It can recognise the owner by the capillary pattern on the palm of the hand, 3D face scanning, fingerprint recognition, password, or remotely via phone or watch. You can also insert an NFC card, as in hotels. Additionally, the camera records video if someone is at the door. The lock is equipped with a colour night vision system, 24 GHz radar, and artificial intelligence to recognise suspicious people. The lock sends an alarm message if someone tries to open it by force. The artificial intelligence tries to recognise suspicious behaviour patterns and will send an alarm even if the intruder has not even touched it. According to the manufacturer, the system performs recognition in less than a second, and the number of AI recognition errors does not exceed 1%.
The high-tech gadget has a 5000 mAh battery that provides up to 4 months of operation. If you plan to leave the lock for a long time, you can insert AA batteries, which will provide an additional six months of battery life. Xiaomi claims that the device has a noise-absorbing design, which makes the mechanism barely audible.
This is a case of using the most advanced technologies when it is impossible to say that the engineers overdid it. It is difficult to recognise a person unambiguously, and this device is responsible for the safety of the home, which requires a particularly cautious approach. The device is not cheap, with a price in China of about $345, but if the technology works as promised by Xiaomi, then Smart Door Lock 4 Pro really has a future.
