The Z10 uses palm vein recognition to identify the vascular pattern beneath the skin, delivering fast, contactless authentication for up to 90 registered users. A built-in camera with two-way audio, accessible through the Dalton app, allows users to view and communicate with visitors remotely. For added reliability, the lock supports six entry methods: palm vein, fingerprint, PIN code, RFID card, mobile app, or physical key. Constructed with an aluminum alloy front and ABS+PC rear housing, the Z10 is rated IP65 for weather resistance and powered by a rechargeable 7.4V lithium battery with Type-C charging. | Dalton | | Z10 Smart Deadbolt with Palm Recognition & Built-In Camera – | Black | Best Buy
