Product Description

Its CNC precision aluminum frame ensures durability and a sleek look, while the radar sensor enables hands‑free, approach‑activated 3D face recognition.
The built‑in HD indoor screen and visual camera provide clear two‑way video intercom via the mobile app, so you can see and speak to visitors remotely. The same financial‑grade 3D structured light technology guarantees accurate identification in outdoor strong light, backlight, or low‑light conditions.

With six unlocking methods (3D face, fingerprint, password, IC card, mechanical key, and APP), the R31 Promax adapts to every user’s lifestyle. Whether you choose the bold matte black or the understated grey, this lock brings both security and style to your front door.
