You can check live activity at your door anytime and view unlocking, alarm, and operation records directly from your phone. Built-in Door Viewer Camera Equipped with a high-definition viewer camera, the indoor screen displays a clear image of the outside area, giving you full visibility of your doorstep. Virtual Password Protection Enhance your privacy with a virtual password feature that lets you enter random digits before or after the correct code. As long as the correct sequence appears in between, the door unlocks securely.

Tamper and Error Alarm If someone tries to force the lock or repeatedly enters the wrong password or fingerprint, the system triggers a loud alarm and instantly sends an alert to your mobile device.
