Biometric Smart Door Lock F030

8-in-1 Unlocking Methods: 3D Facial Recognition, Fingerprint (biometric), Digital Password, IC Card, Smartphone App, Temporary OTP, Remote Unlock via Video Intercom, and Emergency Mechanical Key. Built-in HD Camera & Intercom: Features a wide-angle "cat-eye" camera that allows you to see and talk to visitors via your phone (Tuya/SmartLife app) before granting access. Internal Display Screen: Usually equipped with a 3.5 to 4-inch IPS screen on the interior panel to view the outside corridor without opening the door. High-Security Mortise: Includes a multi-point locking system (visible in the image) with multiple stainless steel bolts for anti-pry and anti-drill protection. Rechargeable Power: Powered by a large-capacity lithium battery (typically 4200mAh – 5000mAh) with a USB emergency power port for jumpstarting. Fully Automatic: The latch bolts automatically retract when verified and extend when the door is closed—no handle turning required. Note: Dimensions may vary slightly by ±1-2cm depending on the specific manufacturer (e.g., Philips, Xiaomi, or OEM brands), but these represent the standard industry sizing for this vertical handle design.
