Why it matters
Built for how you actually get home.
Ultra-Fast Fingerprint Access with High Capacity
The Solity Welkom WR-303B is built around near-instant fingerprint recognition and generous storage, making it a strong fit for households or small offices with many regular users who each need their own registered fingerprint.
Ways to Unlock
A 0.9-second fingerprint unlock with a near-zero misrecognition rate is the primary access method, backed by 3-in-1 access via fingerprint, PIN code and card — with storage for up to 100 fingerprints and 100 cards, which is far beyond what a typical household will ever need to register.
Auto-Lock & Weatherproofing
Instant auto-lock engages the moment the door closes, with customisable timing so you can set exactly how long a delay (if any) suits your routine. A splash-proof design and a silent mode support discreet, all-weather use.
Power
Runs on DC 6V from 4x AA alkaline batteries, with emergency 9V backup power and low-battery alerts fitted for doors 40–50mm thick.
