Smart lock fit
Compare retrofit locks, replacement deadbolts, and handle-style options before changing hardware, keyways, or keypad access on an existing door.
This Palm Vein Smart Lock from Anybell combines security with convenience for busy families. The palm vein scanner unlocks in 0.6 seconds by reading your unique vein pattern—safer than fingerprints because it can't be copied. All biometric data stays local on the device, so your privacy is protected.
The built-in 2K camera and video doorbell give you a clear view of visitors with a 110° field of view. Motion alerts pop up on your phone instantly, and two-way audio lets you talk to delivery drivers or guests from anywhere. No subscription needed for local storage.
You get five ways to unlock: palm vein, passcode, app remote control, or voice commands with Alexa or Google Assistant. The large 10500mAh battery lasts months between charges, and the lock works in extreme temperatures. Installation takes about 15 minutes with standard US deadbolts, and customer support is available 24/7. Ideal for families who want a secure, keyless entry system that's easy for everyone to use.
