Front Door Smart Lock

The DNBeffulgent RA-7 is a Wi-Fi connected deadbolt designed for residential front doors. It combines a fingerprint sensor, touchscreen keypad and app-based control in a single unit finished in black zinc alloy. The lock connects directly to a home network without requiring a separate hub.

Households Wanting Keyless Access

This lock suits families, landlords or Airbnb hosts who need to manage up to 200 users through fingerprints, codes or IC cards. It is not for buyers who require direct remote lock or unlock commands from the app, as the manufacturer notes this function is not supported. Properties without a stable 2.4 GHz Wi-Fi signal should also look elsewhere.

0.3 Second Fingerprint Speed

The biometric reader verifies a fingerprint in 0.3 seconds with a stated 99.9% accuracy rate and stores up to 100 fingerprints. This speed and capacity determine whether the lock can handle high-traffic entry points without delays.

Questions about this item

How do I install the RA-7 deadbolt on a standard front door, and which step do people often get wrong?

The lock fits a standard deadbolt cutout using the supplied hardware; the step most often missed is calibrating the auto-lock timing in the app after mechanical installation so the bolt engages reliably.

What maintenance will the RA-7 need over time, and what parts must be replaced?

The unit runs on four AA batteries (not included); expect to replace them when the low-battery alert sounds, and keep the fingerprint sensor clean for consistent 99.9% accuracy.

What limit appears first during sustained daily use of the RA-7?

The lock stores a maximum of 100 fingerprints and 200 total users; once either cap is reached you must delete existing entries before adding new ones.
