Smart lock
Product Description
Our intelligent door lock is made of military-grade steel materials (galvannealed steel / hot-dip galvanized / cold-rolled steel), integrating the strength of metal structure with intelligent security technology. The main structure is precisely stamped and undergoes multiple protective treatments, supporting four-in-one unlocking methods of fingerprint / password / IC card / mechanical key, suitable for apartment, office, high-end residential and other scenarios, achieving a deep integration of security protection and intelligent convenience.
