6. Operating Instructions
6.1 Unlocking Methods
The device offers multiple secure and convenient ways to unlock:
- Face Unlock: Utilizes dynamic facial recognition with a 0.5-2 meter range. The two-eye 2-megapixel high-definition infrared camera performs 3D liveness detection to prevent unlocking with photos or videos. It works effectively in strong light, backlight, and weak light conditions.
- Fingerprint Unlock: High-sensitivity semiconductor 3D fingerprint collector for quick access with low error recognition rate. Suitable for all ages.
- RFID Card Unlocking: Simply swipe a 125Khz RFID card to open the door. The device supports a capacity of 5000 cards.
- Password Unlock: Enter a predefined password on the device's touch screen.
- Tuya APP Unlocking: Remotely manage and unlock the door using the Tuya Smart App on your mobile phone.
- Temporary Password: Generate and share temporary passwords remotely via the app for visitors.
