The Smart Door Knob Pro is a fingerprint smart lock that replaces a standard door knob. It unlocks by fingerprint in about a second, by passcode on the handle, or from a phone app, and it works with Alexa and Google Home. It stores up to 120 fingerprints and keeps an unlock history, with no subscription. It suits renters and homeowners who want keyless entry without wiring or a monthly fee. Against keypad-only locks it adds a fingerprint reader and app control; against camera-equipped video locks it lacks a camera and doorbell.
