Why it matters
Built for how you actually get home.
Finger Vein Authentication for the Whole Family
The Lockin S50M Pro uses finger vein authentication rather than fingerprints — a method that reads the vein pattern beneath the skin, which tends to work more reliably for children and elderly users whose fingerprints can be harder for standard sensors to read consistently, especially as skin texture changes over time.
Built-In Viewer & Camera
A high-definition internal viewer screen doubles as a video camera, with remote video, calling, wide-angle coverage, night vision and surveillance, so you can check who's at the door without opening it — effectively combining a peephole, an intercom and a security camera into the lock itself.
Security & Smart Home
A fully automatic locking mechanism and multi-facet security intrusion sensors and alerts are built in, alongside a doorbell function. The lock works with the Mijia app (English/Chinese) and Apple HomeKit, with phone notifications and a selectable voice guide.
