    The eufy FamiLock S3 Max is a Grade 1 smart deadbolt with palm-vein entry, a 2K HDR camera, and a video doorbell in one device, suited to households that want keyless access and front-door monitoring together.

    Recommended For

    • Households replacing separate front-door devices with one unit: the S3 Max combines a smart deadbolt, video doorbell, camera, and indoor screen, reducing the need for separate hardware at the entrance.
    • Residents of apartments or homes with opaque front doors who want to check visitors from indoors: the built-in screen acts as a digital peephole without requiring a phone.
    • People who often arrive with bags or packages and want key-free entry: palm-vein recognition offers touchless unlocking, with a keypad and physical key as alternatives.
    • Eufy-app users who want door access and visitor video in one system, with local video storage available without a required cloud subscription.
