You are standing at your front door with groceries in both hands. Rain is starting to fall. Now imagine unlocking the door without putting anything down — just by letting it see your face. That is what the F7 delivers.
The F7 is a biometric door lock that recognizes you in three ways. Look at it, and the face scan unlocks the door. Wave your hand, and the palm vein reader works its magic. Press your finger on the sensor, and the fingerprint lock responds instantly. Three biometric options, all fast, all secure.
But keys are not completely gone. The front door key pad lock lets you type in a 4 to 8 digit code. The anti-peep scramble code means you can add random numbers before and after your real code without breaking it. RFID cards work for kids or older family members. And yes, there is a physical key override if you ever need it. This is what a modern keyless front door lock should be — multiple ways in, no single point of failure.
The video intercom changes everything. A 1MP camera with a doorbell lets you see who is at your door from anywhere. Open the Tuya app on your phone. A visitor rings. You see their face, talk to them through the intercom, and decide whether to unlock. Package delivery? Guest arriving early? You never have to rush to the door again.
Connectivity is built on Tuya WiFi, so no extra hub is required. From the app, you can lock or unlock remotely, share eKeys with family members, and check the audit trail to see exactly who came and when. The F7 also works with Alexa for voice control.
Security features go deep. Double verification mode requires two methods to unlock — face plus fingerprint, code plus palm vein, any combination you choose. A tamper alarm triggers if someone tries to pry the lock open. Incorrect attempt alert locks out the keypad for three minutes after too many wrong tries. There is even an alarm that sounds if someone lingers too long outside your door.
Inside your home, the privacy switch blocks all external access except for the admin and physical key. Only you decide who gets in.
Battery life is simple. The 4200mAh rechargeable battery lasts 3 to 6 months on a full charge. Charging takes about six hours. A low battery alarm warns you through the app and an audible sound. If you forget to charge, the USB-C port accepts emergency power from any power bank.
Built from aluminum alloy with a baking paint finish, the F7 operates in temperatures from -10°C to 60°C. It fits door thicknesses from 40mm to 120mm and works with a 6068 mortise.
For anyone searching through top rated smart door locks, the F7 deserves a close look. It turns your main door into a digital lock for main door that does not just sit there — it sees, listens, and responds. That is not just a lock. That is a smart door lock for home that actually understands who you are.
