Smart Four-Way Door Lock
Fast, flexible access for up to 200 entries
Secure your door with four flexible unlocking methods: fingerprint, password, IC card and mechanical key. This fingerprint door lock recognises a fingerprint in under 0.2 seconds, has a rejection rate below 0.01% and supports more than 100,000 unlocks. It stores up to 200 entries across passwords, fingerprints and cards, making access practical for several users. Password protection locks the keypad for three minutes after five consecutive incorrect entries, while anti-snooping fake-password operation adds privacy. Choose single, temporary, cycle or permanent password modes through the application. A low-battery reminder helps you replace the four AAA batteries in time, and a Type-C port gives this electronic door lock emergency power.
