SwitchBot Lock Vision stores face scans locally with no cloud required

SwitchBot's Lock Vision stores your face scan on the lock itself, not on a company's server somewhere. The Pro version reads palm veins, even wet ones, without any touch required. A 10,000mAh main battery handles daily use, and a backup CR123A cell covers 500 more unlocks if that dies. Smart lock makers have spent years asking you to trust their cloud. This one just doesn't use it.
