3-in-1 Video Smart Lock

The eufy Security S330 combines a 2K HD camera, video doorbell and fingerprint smart lock in a single black unit. It connects via WiFi and works with the eufy Security app, Alexa and Google Assistant for remote monitoring and control. Homeowners wanting an all-in-one entry solution without monthly fees will find it fits that need.

2K camera, 10 000 mAh battery, 50 fingerprints

The 2K HD camera captures clear visitor footage while the rechargeable 10 000 mAh battery powers every feature. Fingerprint recognition stores up to 50 prints, unlocks in 0.3 seconds and reaches a 98 % pass rate that improves with self-learning AI. Local video storage on the Chime requires a separate SD card.

Replaces separate lock, doorbell and camera

This unit replaces a traditional deadbolt, a standalone video doorbell and an outdoor security camera with one installation. The jump is worth it when you want unified app control, voice-assistant unlocking and no subscription costs. It is not suited for doors outside the 35–55 mm thickness range or cross-bore diameters other than 38 mm or 54 mm.

Questions about this item

Will the 8.66 x 3.15 x 7.09 inch S330 fit my existing door prep?

The lock fits crossbore diameters of 38 mm or 54 mm, backsets of 60 mm or 70 mm, a 25 mm hole, and door thickness between 35 mm and 55 mm.

How can I confirm the 0.3 second fingerprint reader and 2K camera are functioning after installation?

Register a fingerprint in the eufy Security app; the lock should unlock within 1 second. Trigger the doorbell and verify a 2K live view and motion alert appear on your phone.

Does the box include the SD card required for local video storage, or must I buy one separately?

The package contains the S330 lock, chime, two mechanical keys, and mounting hardware. A microSD card for the chime's local storage is not included and must be purchased separately.
