Lightning-fast Biometric Recognition, Unlock with a Touch Experience true keyless entry. Equipped with an advanced semiconductor fingerprint sensor, the smart lock achieves recognition in just 0.2 seconds, with an opening time of only 1.5 seconds and an accuracy rate of 99.9%. Whether your hands are full of shopping bags or you're rushing out, a simple touch of your finger and the lock responds instantly. In addition to fingerprint unlocking, a physical key is retained as an emergency backup, and app Bluetooth control is supported.

View detailed unlocking logs to stay informed about family members' entry and exit; remotely manage fingerprint permissions to easily handle visitor needs. The lock supports three modes: always open, normal, and privacy, which you can quickly switch between by simply rotating the fingerprint area. We understand the importance of privacy, so all fingerprint data is stored locally and never uploaded to the cloud, eliminating the risk of information leakage at the source and building a solid security defense for you.
