There is no keyhole on the lock core, and it does not contain any mechanical structure of the traditional lock. In terms of security, it provides 256? Advanced encryption technology is like setting a firewall. You can't peek inside, you can only see invisible characters, which can prevent wireless communication from being cracked. In short, it can really guarantee safety.

To control the Fu Rui lock cylinder, you don't need to download the APP, just need the WeChat applet. It is very convenient to control the lock with your mobile phone after binding the account.

Overall, it's still very good. I hope I can help you.
