Smart technology, let people do less things, and make things more secure.

What I've experienced most is the smart door locks.

When you leave the house, if the door is left open, your own cell phone receives an alarm alert.

And smart locks no longer need to worry about forgetting the key, the use of fingerprints and passwords can be unlocked ------

Save the trouble of the key, but also make a door more secure and intelligent, which is the technology of the "sense of security"!
