Imagine unlocking your front door without fumbling for keys or even touching a sensor. That is exactly what the FM880 Pro smart lock delivers with its advanced palm vein recognition. Just hold your hand near the lock, and it opens instantly — more secure than a fingerprint and far more convenient.

This smart door lock also features a built‑in video doorbell with a 1MP camera. Whether you are at work or on vacation, you can see and talk to visitors through the Tuya app. The lock even detects if your door is left open, giving you one less thing to worry about.

Connectivity is handled by Tuya WiFi, so there is no need for an extra gateway. From the app, you can lock or unlock remotely, view the audit trail to see every time someone enters, and share timed access codes with housekeepers or dog walkers. The FM880 Pro stores up to 300 credentials — fingerprints, codes, or RFID cards — with code lengths from 6 to 10 digits.

Safety is built into every detail. The anti‑peep scramble code prevents strangers from learning your password by watching you type. Double verification mode requires two unlock methods for high‑security situations. A tamper alarm triggers if someone tries to pry the lock open, and the privacy switch blocks all external access when you are home.

Rated IP65 waterproof, this keyless entry door lock stands up to rain, dust, and temperature swings from -20°C to 50°C. The 5000mAh lithium battery lasts 3 to 6 months, with a USB‑C port for emergency power. Please note that this model works exclusively with Tuya and does not support Alexa or Google Home.

For FM880 standard version:

If you prefer a straightforward smart deadbolt without the video doorbell or palm vein sensor, the FM880 offers the same reliable core experience. It unlocks via fingerprint, smartphone app, password, RFID card, or physical key. The Tuya app gives you remote control, an audit trail, and the ability to share timed codes with visitors. Like its Pro counterpart, it includes anti‑peep scramble codes, double verification mode, tamper alarm, privacy switch, and IP65 waterproofing. The FM880 runs on four AA batteries that last up to one year, with a USB‑C emergency port for backup power.
