What reviewers like
- Fast, accurate fingerprint reader.
- Local video storage with no fee.
- One device for lock and doorbell.
What to watch for
- The camera’s view is narrow; packages at your feet may be out of frame.
- The camera uses a lot of battery, so expect regular charging.
- Bulkier than a normal deadbolt.
Who should buy it
Buy it if you want a lock and a doorbell in one, and you have no doorbell wiring. Skip it if you want to see packages; the Eufy E340 doorbell has a downward camera.
Battery reality
Running a camera on a lock battery is hard. Reviewers report the E330 needs charging more often than a lock alone. A rechargeable battery means you charge it rather than buy new cells. Busy doors mean more charging.
Fingerprints and codes
The fingerprint reader is quick and works from different angles, per Tom’s Guide. Give guests codes in the app and remove them when they leave.
Quick answers
Does it need a subscription? No.
Does it work with Apple Home? No. SafeWise notes there is no Apple Home support. It works with Alexa and Google Assistant.
Before you buy any smart lock
- Measure your door: thickness, backset (the distance from the edge to the center of the hole) and whether the deadbolt drags. A lock motor struggles with a bolt that sticks.
- Check your ecosystem: Apple Home, Google Home, Alexa, Z-Wave or Matter.
- Decide how you will get in when batteries die. Most locks have a key, a USB-C or 9V jump point, or both.
- Think about who gets codes. Guest codes and schedules are a big part of the value, and you can revoke them at any time.
- Renters should check the lease before replacing a lock; a retrofit model may be the safer route.
One device or two
Combining a lock and doorbell saves a hole in the wall and a second app. The trade is that the camera sits at lock height, lower than a normal doorbell, with a narrower view. Reviewers found it fine for faces at the door and weaker for anything off to the side or on the ground. If you already have a doorbell, buy a plain lock instead.
Setup notes
The E330 replaces your whole deadbolt. Check the door thickness and backset in Eufy’s guide, charge the battery before install, and enroll a couple of fingers per person. Turn down motion sensitivity if you want to stretch battery life, and set activity zones so the camera ignores the street. A local-storage camera is also a privacy plus: clips stay on the device unless you choose to share them.
Install and setup notes
Measure your door thickness and backset before you buy, and check that your Wi-Fi reaches the front door, since the camera and remote unlock depend on it. Charge the battery fully before setup, and keep a physical key somewhere safe in case the battery runs flat.
Is the Eufy Video Smart Lock E330 on sale for Black Friday?
It is one of the products I am watching this season. I do not list sale prices here because they change by the hour and differ by color, bundle and store. Compare against the price you see in the weeks before the sale, and check whether a bundle adds things you will not use.
Our take
AI Score note: research-based, not hands-on. The best lock-plus-camera combo in reviews, if you can live with charging. This is my editorial read of published reviews, not a rating.
