eufy Video Smart Lock E330 3-in-1
Score: 82/100
Sifely Fingerprint Smart Deadbolt
Score: 75/100Rankings
The eufy Security Video Smart Lock E330 is an innovative all-in-one deadbolt that integrates a 2K HD video camera, doorbell, and keyless entry. Its primary strength lies in its subscription-free local storage and robust BHMA-certified build quality. However, users frequently report inconsistent battery life and limited smart home ecosystem compatibility due to the lack of HomeKit support.
The Sifely Fingerprint Smart Deadbolt offers high-capacity user management with over 100 fingerprints and codes, suitable for busy households. It requires a separate gateway for full smart features, which is a notable trade-off for hub-free users. It is best suited for rental property managers and families needing flexible access logging.
