3-in-1 Functionality: Lock, Camera, and Doorbell in One
The eufy E330 Black Video Smart Lock isn’t just a smart lock. It’s a security ecosystem built into your front door. This device seamlessly integrates:
- A smart fingerprint-enabled lock
- A video doorbell with live HD streaming
- A wide-angle security camera with two-way audio
All components are housed in a sleek, weatherproof unit — making it one of the most space-efficient and intelligent door upgrades on the market.
Instead of buying and installing three separate devices, you get everything in one clean, powerful solution that looks as good as it functions.
Fingerprint Keyless Entry: Fast, Secure, and Touch-Based
Say goodbye to keys — the eufy E330 Black Video Smart Lock offers ultra-fast fingerprint recognition, unlocking in under 0.3 seconds. The 99% accuracy of the fingerprint sensor means you’ll gain access instantly and securely every time.
You can register multiple fingerprints for household members, babysitters, or trusted visitors — and remove them easily from the app when needed.
Why fingerprint access rocks:
- No more lost keys or forgotten codes
- No fumbling at the door with arms full of groceries
- Secure enough to replace traditional locks entirely
It’s a smarter, faster, and more secure way to enter your home — literally at the touch of a finger.
Built-In 2K HD Camera for Live View and Motion Detection
The video camera on the eufy E330 Black Video Smart Lock delivers 2K resolution — giving you crystal-clear views of anyone at your doorstep. With a 160° wide-angle lens, you can see from head to toe, or even spot packages left on the ground.
Even better, the camera supports:
- Live view from your phone
- Two-way talk so you can greet guests or warn strangers
- Night vision for reliable visibility after dark
- Motion detection alerts, sent instantly to your phone
Whether you’re upstairs or on vacation, you’ll know exactly who’s outside your home and why.
Doorbell with Chime: Alerts That You’ll Actually Hear
Built right into the system is a video doorbell that rings a physical chime when someone presses it — a key feature often missing from standalone camera-based locks.
The chime unit plugs into any standard outlet and can be placed wherever it’s most convenient in your home. No more relying solely on smartphone notifications — the eufy E330 makes sure you don’t miss a visitor, package delivery, or alert even if your phone is on silent.
You can also choose from a variety of chime tones and volume levels to suit your preferences.
Smart App Control and Notifications
The eufy Security app acts as your control center. It allows you to:
- Lock/unlock remotely
- Receive real-time notifications for motion, doorbell rings, or unlock events
- View video history and live feeds
- Set passcodes and manage user access
- Customize notification zones and motion sensitivity
The app is intuitive, clean, and powerful — everything you’d expect from a premium smart home brand like eufy.
It also integrates with Apple Watch, so you can unlock your door from your wrist — handy when coming home on a run or bike ride.
Compatible with Alexa and Google Assistant
The eufy E330 Black Video Smart Lock works with both Amazon Alexa and Google Assistant, making it easy to integrate into your broader smart home system.
Voice controls and routines include:
- “Alexa, is the front door locked?”
- “Hey Google, show me the front door camera.”
- Set lights to turn on when someone rings the doorbell
- Automate routines when the door unlocks
While for security reasons you can’t unlock via voice, the hands-free awareness and automation features add serious value.
Local Storage with No Monthly Fees
Unlike other systems that require subscriptions, eufy offers local video storage — up to 16GB on the device itself — with no monthly fees required for basic usage.
This means you own your data, maintain privacy, and avoid paying for cloud services unless you want extended storage or cloud backup options. For most users, local footage with instant alerts is more than enough.
A huge plus: videos are encrypted, so only you can view them — even eufy can’t access your data without your permission.
Built for All Seasons: Weatherproof and Durable
The eufy E330 Black Video Smart Lock is designed for all-weather use, rated to perform in:
- Rain and snow
- Extreme cold and heat
- Dusty and coastal conditions
Its sleek, IP65-rated housing protects sensitive electronics, while the fingerprint reader stays responsive even in cold or humid conditions.
Whether installed on a front porch, back door, or garage side entry, it’s built to endure — and keep working year after year.
Easy DIY Installation with Everything Included
Despite its advanced feature set, the eufy E330 is surprisingly simple to install. It fits standard US door locks and comes with:
- All required mounting hardware
- Step-by-step instructions in the app
- Templates for perfect alignment
- A physical backup key if needed
Installation typically takes 30–45 minutes for most users. If you’re replacing an existing deadbolt, it’s a smooth process — no drilling or special tools required.
