Arpha D280 Smart Door Lock with Fingerprint App Control and 100 Codes, Waterproof 5-in-1 Electronic Lock

The Arpha Tuya Smart Door Lock D280 Set combines state-of-the-art access control with versatile app operation and a robust design. It's a 5-in-1 lock that can be opened via fingerprint, password, e-key, app, or mechanical key. The D280 supports up to 50 stored fingerprints, more than 250 different PIN codes, and allows for sharing access rights or designating administrators. This gives you security and flexibility in a single device.

Fingerprint recognition uses AI-based technology that achieves a recognition rate of 99.99%. The lock recognizes your fingerprint in just 0.3 seconds, and the door unlocks within one second. This eliminates the need for cumbersome keys and the hassle of entering codes in everyday life.

For remote control and home automation, the lock is compatible with the Tuya platform. With the separately available Arpha G1 gateway, the lock can be integrated into smart home systems and controlled via Alexa or Google Assistant. Using the app, you can lock and unlock the lock, manage users, or view access logs from anywhere at any time. Codes can be assigned as one-time PINs, permanent codes, or scheduled time codes. An automatic locking function with an adjustable timer (e.g., 10–30 minutes) ensures that the door is not left open.

Installation is straightforward: The lock can be mounted on either side for left- or right-hand hinges and fits door thicknesses from 35 to 55 mm. Backset lengths of 60 mm or 70 mm are supported. Installation can be completed in just a few minutes without drilling or complicated adjustments.

The casing is made of robust zinc alloy and meets common certifications such as CE, EAC, and FCC. It connects wirelessly via Bluetooth or 2.4 GHz Wi-Fi. In addition to fingerprint and app unlocking, you can also unlock with a password, e-key, or conventional key. Features such as adding virtual digits before and after the code (anti-peep), remote password generation, automatic locking after incorrect attempts, and other security mechanisms ensure the D280 consistently protects your privacy.
