If you want a smart lock that feels like a complete security upgrade (not just a keypad), J28 is built for you. It combines fast everyday access with advanced visitor monitoring, giving you more control over who enters your home, office, or short let property.
1) See who is at your door, anytime
J28 comes with a built in camera and supports Tuya remote visual intercom. When a visitor presses the doorbell, your app receives a video call so you can respond in real time and decide whether to unlock.
2) 6 convenient ways to unlock
No more “where is the key?” stress. J28 supports multiple access options so everyone can use what works best:
-
3D face recognition unlock
-
Fingerprint unlock
-
Password unlock
-
Card unlock
-
Mechanical key unlock
-
App remote unlock (Tuya)
3) Indoor screen for quick, clear viewing
From inside your space, the indoor display screen lets you view the visitor clearly without rushing to the door. This is perfect for families, offices, and anyone that wants extra confidence before opening.
4) Smart app control and user management
With Tuya app intelligent management, you can control access from your phone. Add users, manage entry methods, and unlock remotely when needed.
5) Share access safely with temporary passwords
Expecting a guest, cleaner, staff member, or delivery? J28 lets you send a temporary password so people can enter within the allowed time, even when you are not home.
