What Experts Agree On
What Experts Love
- ✓ Palm-vein recognition captures over 50,000 data points and unlocks in 0.6 seconds at 99.9% accuracy, a forgery-resistant biometric that works in the dark without exposing your face.
- ✓ Combines a deadbolt, a 150-degree 2K HDR video doorbell, and a 4-inch 1080p interior screen, so you answer the door and verify a visitor from one device.

- ✓ Two rechargeable batteries deliver up to 5 months of use with 4 AAA backup cells so a dead pack never locks the door.
Common Criticisms
- ✗ It unlocks by palm-vein rather than face, so true face-walk-up unlock is not available and you still raise a hand to the reader.
- ✗ Reviewers found the smart-home setup fiddly and rated the video as only adequate for the $329.99 all-in-one price.
