eufy Video Smart Lock E330 Review: A Subscription-Free 3-in-1 Lock, Camera and Doorbell (Without a Door Sensor)
An all-in-one 2K camera, doorbell and fingerprint deadbolt with local storage and no monthly fees, but it lacks the open-door sensor of the pricier S330, and motion detection needs tuning.
The eufy Video Smart Lock E330 packs a fingerprint deadbolt, a 2K camera and a doorbell into one device, with local 8GB storage (or a HomeBase) and no monthly subscription, which owners repeatedly cite as the big draw over camera locks that charge fees. The fingerprint reader is fast and reliable even in heat or rain, the build feels solid, installation is generally easy, and you get full remote control from anywhere (one owner runs it from 3,200 miles away). Auto-lock schedules, per-person codes and fingerprints with entry alerts, an upgradeable key cylinder, and integration with Alexa, Google Home and Home Assistant round it out, and eufy's US-based customer support earns exceptional praise (call-backs within an hour even out of warranty). The key limitation to understand is that the E330, unlike the pricier S330, has no open-door sensor, so with auto-lock on the deadbolt can extend even while the door is open (on a timer), which some owners find defeats the point unless they use a schedule. Motion detection can miss people (better with tuning or a HomeBase), the built-in rechargeable battery often lasts only a few months with heavy use, and away-from-home latency can be significant. There is no HomeKit or Matter. For a subscription-free all-in-one lock plus camera, it is a strong value, just know the door-sensor and battery trade-offs going in.

Who is the eufy E330 for?
This is a 3-in-1 Wi-Fi deadbolt combining a fingerprint lock, a 2K camera and a doorbell, aimed at people who want a lock and a video doorbell in one device with no subscription. It unlocks via fingerprint, a keypad passcode, the app remotely, and a physical key, records locally to 8GB of built-in storage (or a HomeBase, with up to 16TB and AI facial recognition), and works with Alexa, Google Home and Home Assistant. It has built-in Wi-Fi and a rechargeable battery with a USB charging port, rated around 8 months. It best suits those who want an all-in-one lock plus camera, subscription-free storage, reliable fingerprint entry, and Alexa/Google/Home Assistant integration. If you need a true open-door sensor for auto-lock, catch-everything motion capture, HomeKit or Matter, read the caveats, and consider the S330, first.
What buyers love
The all-in-one, subscription-free design is the biggest draw: owners love getting live video, two-way audio, remote Wi-Fi control and real-time alerts with no annual fee, storing footage locally on the 8GB internal storage or a HomeBase 3 (which adds AI facial recognition and up to 16TB via your own drive). The 2K camera is sharp, and the fingerprint reader is a highlight, fast and recognized every time even in heat, rain or when wet, notably better than expensive biometric locks some owners replaced. Build quality is solid (hefty aluminum), installation is generally easy, and one owner reports 18 months with no reboots. There are four ways in (fingerprint, keypad, physical key, and app), with per-member codes and fingerprints, entry notifications, and constant or temporary access. Auto-lock can run on a schedule (locking overnight or during school hours) and warns if the deadbolt is stuck, and it integrates with Alexa (video streaming), Google Home and Home Assistant, with alerts even on an Apple Watch. Owners also value the upgradeable, bump- and pick-resistant key cylinder, the high-capacity removable battery with USB-C charging, and remote control from thousands of miles away. eufy's US-based customer support draws standout praise, with quick call-backs even out of warranty.
What to know before you buy
The most important thing to understand is that the E330 has no open-door (door-ajar) sensor, unlike the S330. This means with auto-lock enabled the deadbolt can extend on a timer even while the door is wide open (for example if someone steps out to take the trash), so owners who want instant lock-on-close either use a schedule, turn auto-lock off, or step up to the S330 (which adds the door sensor and a chime with a microSD slot). Motion detection can be uneven, sometimes only capturing the back of a departing delivery person, and improves with sensitivity and zone tuning or a HomeBase to cut false alarms. The built-in rechargeable battery often lasts only about three to six months with heavy traffic or many features enabled and takes a while to recharge, so a spare battery is a common recommendation. Away-from-home latency can be significant (push notifications may take a minute, and locally recorded video needs time to decrypt remotely), and initial setup and the app confuse some owners (no printed instructions beyond downloading the app, a deadbolt-stuck error during calibration, and a fiddly multi-user setup where both locking and unlocking require your fingerprint). Fingerprints can also fail with dirty or dusty fingers. Storage is the 8GB internal or a HomeBase, there is no microSD slot on the lock itself, and there is no Apple HomeKit or Matter.
Is the eufy E330 worth it?
For a subscription-free, all-in-one lock, camera and doorbell, the eufy Video Smart Lock E330 is a strong value: a sharp 2K camera, reliable fingerprint entry, solid build, easy install, local storage, remote control from anywhere, and excellent customer support. The catch is the missing open-door sensor, which makes auto-lock less smart than the S330 (the deadbolt can extend with the door open), plus motion detection that needs tuning, a battery that can need charging every few months, and notable away-from-home latency, with no HomeKit or Matter. Buy the E330 if you want the all-in-one, no-fee concept and can live with schedule-based auto-locking; if the open-door sensor and instant lock-on-close matter to you, spend a bit more on the S330 instead.
Frequently asked questions
What's the difference between the E330 and the S330?
The main difference is that the S330 has an open-door (door-ajar) sensor and the E330 does not. With the E330, auto-lock extends the deadbolt on a timer even if the door is open, whereas the S330 waits until the door closes. The S330 also includes a chime with a microSD slot. Otherwise the two are very similar 3-in-1 locks with the same 2K camera and fingerprint reader.
Does it require a subscription?
No. Video records locally to the E330's 8GB built-in storage or to a HomeBase (which supports large local drives and adds AI facial recognition). Live view, two-way audio, remote control and real-time alerts all work with no monthly fee.
How reliable is the fingerprint reader?
Very. Owners consistently report it recognizing their print every time and quickly, even in heat, rain or when wet, and several found it far more reliable than expensive biometric locks they replaced. It can occasionally fail with dirty or dusty fingers, and you can also unlock via keypad code, the app, or a physical key.
How long does the battery last?
It uses a high-capacity rechargeable built-in battery with a USB-C charging port, rated around 8 months. Real-world life is often shorter, roughly three to six months, with heavy door traffic or many camera features enabled, and recharging takes a while, so many owners buy a spare battery to swap in.
Does it work with Alexa, Google Home or Apple HomeKit?
It works with Alexa (including video streaming), Google Home and Home Assistant, and can send alerts to an Apple Watch. It does not support Apple HomeKit or Matter. Note that away from home, notifications and remote video can be delayed by up to a minute or more.
