eufy Video Smart Lock E330 Review
Bottom Line
Choose it if you want one app for lock, doorbell, camera, quick fingerprint access, and no subscription storage. Skip it if you take long trips, have a screen/storm door, or want battery life that reviewers found predictable.
Best for
Best for homeowners with a standard door setup who want one device for smart lock, doorbell, camera, app control, fast fingerprint access, and local storage without a subscription.
Not for
Not for screen-door or storm-door setups, long trips without battery management, or buyers who need HomeKit, rekeying, siren features, or broad camera coverage from a door-mounted lock.
Verdict
The eufy Video Smart Lock E330 earns praise as a compact all-in-one lock, doorbell, and camera. Reviewers repeatedly found setup easy, the app straightforward, fingerprint entry fast, notifications prompt, and 2K video useful for monitoring the door. The tradeoff is that the camera and smart features make the lock more demanding than simpler smart deadbolts: battery reports range from severe drain to several months, and screen doors, storm doors, deep jambs, or awkward door angles can weaken the camera experience. It works best when the door layout suits the camera and the owner is willing to manage recharge intervals.

Several reviewers reused existing strike plates or avoided optional strike plates, though fit still depends on the door.

A hub is not strictly required for recordings because onboard storage is available, though HomeBase can add functions and storage options.

Voice control is supported through Alexa and Google, including voice-assistant lock control in the review evidence.
-
Key override support is reliable in the reviewed evidence, with included physical keys and emergency USB-C power options noted.

The touch-sensitive keypad/touchscreen area is functional and illuminated on interaction, though visibility depends on conditions.
-
Wrong-try protection can lock the device down after incorrect PIN or fingerprint attempts, giving it a supported failed-attempt lockout feature.
-
Camera and doorbell performance is generally strong for 2K clarity, night vision, and detection, but field of view and placement limitations reduce consistency.

Wi-Fi is necessary and works well in some tests, but reviewers note 2.4 GHz setup and dependence on wireless network quality.
-
Bluetooth appears as a supported unlocking path in the review evidence, alongside physical key access.
-

-

Finish evidence is limited but positive, with one reviewer noting the matte finish helps reduce visible fingerprints.
Cons
-
Battery life is the clearest mixed area: some reviewers saw weeks or two to three months, while one reported roughly six months.
-
Door compatibility is conditional: standard deadbolt setups work, but screen doors, storm doors, spacing, strike plates, and door geometry can cause compromises.
-
The keyway is a limitation because multiple reviews state the lock cannot be rekeyed or does not support common rekeying.
-
Door-sense is weakly supported because one reviewer specifically wanted a sensor to know whether the door is open or closed.
-
One review states the E330 lacks a siren, so there is no supported siren loudness evidence beyond doorbell/chime behavior.
