The YF12 Smart Door Lock offers versatile unlocking methods for maximum convenience and security. It features advanced fingerprint recognition, supporting up to 50 fingerprints, including 10 administrator users, ensuring fast and secure access. In addition, users can choose to unlock the door using a 6-12 digit passcode (up to 200 entries), an encrypted M1 card (up to 200 cards), or a traditional mechanical key as a backup. The lock is also compatible with Tuya Smart or Smart Life mobile apps, allowing remote access from your smartphone for even greater convenience.

The YF12 is built to ensure the highest level of security and privacy. Its anti-peeping password feature allows you to add random digits before or after your correct code, making it nearly impossible for someone to observe your password. The lock also includes a low voltage alarm that will notify you when the battery falls below 4.8V, so you can replace it before it runs out. In case of an emergency, the lock provides an emergency power supply via a USB port. For added protection, the system will trigger an alarm in case of tampering and automatically enter dormancy after 20 seconds of inactivity.

Designed for reliability and long-term performance, the YF12 operates on DC 4.8V-6.5V (using 4 AA alkaline batteries). It draws an average current of 200mA, with a maximum of 300mA. The fingerprint sensor has a high resolution of 508 DPI, ensuring accurate recognition with a false rejection rate of less than 1%. The lock also supports NFC card access at a frequency of 13.56 MHz, with the ability to store up to 200 cards. It can operate in extreme temperatures, ranging from -25°C to 60°C, and is anti-static, with protection against contact discharge of ±8KV and air discharge of ±15KV.
