You can also check the door lock's open/close status, history, battery level, etc., at any time from the app. When the door is opened or closed, a notification is sent to the app, and an alarm sounds when the door is ajar. Furthermore, if you unlock the door with a pre-set emergency fingerprint/emergency password, the app will notify your family of the danger. When the battery level is low, a notification prompting you to charge will be sent to the app. [Measures against Battery Drain and Lockout Risks] It uses CR123A single-use lithium batteries that are resistant to cold, and can smoothly operate and unlock doors even in extremely cold regions where temperatures drop to -20 degrees Celsius.

When the battery level is low, a sound will be emitted from the main unit, and a notification will be sent to the app. Furthermore, with the industry's first "micro-current unlocking function," even if the battery level is significantly low and the remaining power is insufficient to start Lock Ultra, you can unlock the door in an emergency, preventing lockout.
