I don't think the technology is very good I have a basis for saying this:
From 2065438 to May 2009, China Consumers Association conducted a comparative test on 29 mainstream smart door lock products. The results show that 48.3% of the samples have security risks when passwords are opened, 50% of the samples have security risks when fingerprints are opened, and 85.7% of the samples have security risks when information identification cards are opened.
Consumer feedback: There are many problems in the use process. Sometimes the password is entered correctly, but the input error is displayed. If you forget to change the battery, the lock will die and you can't get in. It's convenient, you don't need to bring a key, but in fact, you don't feel so safe.
What problems may occur when consumers use smart door locks?
According to the Consumer Satisfaction Survey Report of Smart Door Locks released by Consumer Big Data Research Institute, 70% of the respondents believe that smart door locks are most likely to be unlocked abnormally or unable to unlock. In addition, consumers are also worried that smart door locks cannot be unlocked due to insufficient batteries; The fingerprint is unreliable, and it can't be recognized after getting wet or sweating; Face recognition can't wait.
Deputy Secretary-General of China Consumer Protection Law Research Association reminded consumers not to use or turn off the face recognition function and remote unlocking function as far as possible. He said: "Because these functions may be relatively new objectively, they actually pose the greatest security risks. In the process of daily use, we should pay attention to the preservation of IC cards to prevent fingerprints from being read or copied. These are all things that consumers should pay attention to.
