• 1. This spherical smart lock integrates both keypad entry and fingerprint recognition capabilities. It is suitable for doors ranging in thickness from 35 to 55 mm, provided that the door's borehole dimensions match those illustrated in the product images. The lock cylinder orientation is adjustable to accommodate either left-opening or right-opening doors. An internal rotary knob allows users to toggle between a "normally open" mode and an "auto-lock" mode (which automatically locks the door after 5 seconds).
• 2. This smart door lock operates on the "Tuya Smart" IoT platform. It supports connectivity via Bluetooth on your mobile phone. Once successfully connected, you can use the accompanying mobile application (App) to monitor the lock's status in real-time, manage access permissions, register fingerprints, generate time-sensitive dynamic passcodes, review unlock logs, and utilize a variety of other smart features.Note: Gateway equipment is not included and must be purchased separately.
• 3. This fingerprint door lock supports multiple unlocking methods, including fingerprint recognition and passcode entry. It can store up to 100 fingerprints and 50 unique passcodes. All fingerprint and passcode data is stored locally within the device itself and is not uploaded to the cloud; consequently, performing a factory reset on the lock will result in the complete and permanent deletion of all such data. Note: Gateway equipment is not included and must be purchased separately.
• 4. Constructed from a composite of aluminum alloy and stainless steel, this spherical lock is robust and durable, and incorporates advanced encryption technology. Additionally, it comes equipped with backup mechanical keys and an emergency power port for emergency unlocking situations. If you have added a "Gateway" device within the Tuya App—and subsequently paired this smart lock with that gateway—you can, in addition to the standard unlocking methods mentioned above, remotely control the lock via your mobile phone from anywhere, at any time. Note: The Gateway device must be purchased separately.
• 5. This security lock features a built-in rechargeable battery that provides over 6 months of battery life on a single full charge (frequent unlocking may reduce this duration). When the battery level is low, the lock body will issue a warning after every subsequent unlocking attempt: it signals its status by flashing a red light accompanied by a continuous "beep-beep-beep" sound. Please recharge the lock promptly. Simply connect a 5V power bank to the Type-C charging port located at the bottom of the lock body. A full charge takes approximately two hours, and there is no need to remove the lock from the door during the charging process.
