• Anti-Peep Keypad: Enhances password security by allowing users to add random numbers before and after their actual passcode, preventing shoulder surfers from guessing the correct sequence.
• Auto-Lock Function: You can configure the lock to automatically engage after a set time period through the mobile app, ensuring the door remains locked even if forgotten manually. The feature can also be disabled temporarily if needed.
• Passage Mode: Allows the lock to remain unlocked for a designated duration (set via the app), useful when receiving packages, hosting guests, or during short absences where re-locking isn’t desired.

Benefits & Use Cases

This smart lock is particularly beneficial for individuals living alone, busy families, or professionals who value convenience and security. Its fingerprint scanner provides instant access without the risk of lost or duplicated keys, making it perfect for parents dropping off children at school or travelers returning late at night.

Property managers and landlords will appreciate the granular control offered through recurring and one-time codes, allowing them to issue temporary access to tenants or service providers without needing physical keys or site visits. The access logs offer accountability and traceability, which is valuable for both security and administrative purposes.

In rental units, the ability to remotely generate passcodes means no more lost key deposits or emergency lockout fees. Guests arriving outside of regular hours can gain entry independently, enhancing hospitality and flexibility.

The backlit keypad ensures usability in complete darkness, while the anti-peep feature protects against visual hacking of your passcode. For those concerned about noise, silent mode allows discreet entry into shared living spaces.

With manual override capability and low-battery warnings, the lock remains functional during unexpected situations like power outages or app synchronization issues. This reliability makes it suitable for both everyday homes and commercial applications where uninterrupted access is critical.
