This smart door lock is equipped with anti-peeping password technology, allowing users to input random dummy digits before and after the actual password to effectively guard against password peeking and theft, ensuring comprehensive home entry security. It also integrates an App remote control and electronic key (Ekeys) management system, enabling users to configure multiple types of passwords, authorize temporary or permanent Ekeys for family members, guests, or tenants, and access complete access logs via a dedicated mobile application for refined permission control. Its auto-lock function supports customizable duration settings (typically 5–900 seconds), automatically locking the door within the preset period after closure to eliminate the security risk of forgotten locking. Furthermore, with a dedicated gateway (sold separately), it enables gateway-enabled remote control, allowing users to remotely lock/unlock the door, monitor real-time access records, and inspect lock status via the App from anywhere, achieving full-scenario intelligent security management.
