With a \”beep\” sound, the door automatically opened!
Nowadays, more and more families are beginning to use fingerprint touch or password input to open their doors. The emergence of smart locks eliminates the need for people to carry keys or worry about being unable to enter the door because they forget to bring the keys, thus greatly improving the convenience of life.
Recently, a short video was circulated on the Internet, recording that around 4 a.m., a door equipped with a smart lock opened automatically without anyone operating it. The family is all asleep, but the door that should have been closed has been opened for no reason. It is very scary to think about it. Some people say that it is because the smart lock is out of power. So is it possible for the smart lock to automatically pop open when there is no power supply?
