Let’s be honest—your front door is more than just an entry point. It’s your first line of defense, your peace of mind, and often, the first impression guests have of your home. But traditional locks? They’re stuck in the past. Keys get lost, duplicates multiply, and you’re always wondering: Did I lock it? Worse, if someone rings the doorbell while you’re at work or on vacation, you’re left in the dark—literally.
That’s where the eufy Security Video Smart steps in. This isn’t just another smart lock. It’s a complete front-door security ecosystem rolled into one sleek, weatherproof device. Imagine a deadbolt that recognizes your fingerprint, streams crystal-clear video to your phone, and doubles as a smart doorbell—all without requiring a monthly subscription. At $259.99, it’s a premium investment, but after spending weeks testing it on my own front door, I can confidently say it delivers on its promise of convenience, security, and reliability.
What makes the eufy Security Video Smart truly noteworthy is its rare combination of advanced features in a single package. Most smart locks offer one or two functions—keyless entry or remote access—but few integrate high-definition video, real-time alerts, and biometric authentication seamlessly. Plus, with no recurring fees and a robust build designed to withstand extreme weather, it stands out in a crowded market of subscription-heavy alternatives. Whether you’re a tech-savvy homeowner, a frequent traveler, or someone who just wants to stop fumbling for keys, this device could be a game-changer.
What is the eufy Security Video Smart?
The eufy Security Video Smart (model S330) is a cutting-edge 3-in-1 smart security device that combines a fingerprint-enabled keyless entry deadbolt, a 2K HD video doorbell, and a motion-activated surveillance camera into one compact unit. Designed for both US and Canadian homes with standard deadbolt installations, it replaces your existing lock without requiring drilling or complex wiring. It connects directly to your home Wi-Fi network and syncs with the free eufy Security app, allowing you to monitor, control, and communicate with visitors from anywhere in the world.
At its core, the eufy Security Video Smart is built around five unlocking methods: fingerprint recognition, the mobile app, voice commands via Alexa or Google Assistant, a built-in keypad, and traditional physical keys (included). The integrated 2K camera captures sharp, color-rich footage day and night, while the built-in microphone and speaker enable two-way audio communication. A motion sensor triggers instant alerts, and the included Chime base station ensures stable connectivity and local video storage via a microSD card (up to 128 GB, sold separately).
Targeted at homeowners who value both convenience and security, the eufy Security Video Smart appeals to a wide range of users—from busy families and remote workers to Airbnb hosts and elderly individuals seeking easier access. Its BHMA certification and IP65 water resistance rating make it suitable for all climates, and the massive 10,000 mAh battery promises months of use between charges. With 24/7 customer support and a 12-month warranty, eufy backs this product with confidence, reinforcing its position as a serious contender in the smart home security space.
Key Features of eufy Security Video Smart
✅ 3-in-1 Triple Security: Lock, Camera & Doorbell
The standout innovation of the eufy Security Video Smart is its seamless integration of three critical front-door functions. Unlike competitors that require separate devices—a smart lock here, a video doorbell there—this unit consolidates everything into a single, streamlined design. The result? Fewer gadgets, less clutter, and a unified user experience.
The fingerprint scanner uses advanced capacitive sensing to recognize authorized users in under a second. During my testing, it consistently unlocked on the first try, even with slightly damp or dirty fingers. The 2K HD camera delivers impressively clear video, capturing fine details like license plates and facial features from up to 15 feet away. At night, infrared night vision kicks in automatically, providing full-color footage thanks to built-in ambient light sensors and supplemental LEDs.
As a doorbell, it performs just as well. When someone approaches, motion detection triggers a live feed on your phone. Tap to answer, and you can speak through the built-in speaker—perfect for telling delivery drivers to leave packages safely or reassuring neighbors during emergencies. The Chime base station enhances reliability by acting as a Wi-Fi extender and local storage hub, reducing lag and ensuring recordings aren’t lost during internet outages.
✅ Five Convenient Unlocking Methods
One of the biggest pain points with smart locks is limited access options. The eufy Security Video Smart solves this with five distinct ways to unlock your door—each tailored to different scenarios and user preferences.
Fingerprint recognition is the fastest and most intuitive method. I registered four fingerprints (two hands, two family members), and each worked flawlessly. The sensor is positioned ergonomically on the exterior handle, so you don’t need to fumble or reposition your hand. For guests or service providers, the 4–8 digit PIN keypad offers temporary or permanent codes—ideal for housekeepers, dog walkers, or Airbnb renters.
The eufy Security app provides full remote control. From anywhere with internet, you can lock or unlock the door, view live video, check access logs, and manage user permissions. Voice control via Alexa or Google Assistant adds another layer of hands-free convenience—“Hey Google, unlock the front door” works smoothly, though it requires enabling voice match for security.
And yes, physical keys are still included. While I rarely used them, it’s comforting to know they’re there as a backup during power outages or app glitches. The dual-cylinder design means keys work from both inside and outside, maintaining traditional functionality without compromising smart features.
✅ Remote Management & Real-Time Notifications
One of the most empowering aspects of the eufy Security Video Smart is its ability to keep you connected—no matter where life takes you. The eufy Security app (available for iOS and Android) serves as your command center, offering intuitive controls and detailed insights.
Whenever motion is detected or someone rings the virtual doorbell, you receive instant push notifications. These include a thumbnail image and timestamp, so you can quickly assess the situation. Tapping the notification opens a live video stream, allowing you to see and speak to the person at your door. I tested this while traveling—receiving an alert about a package delivery, I remotely unlocked the door for a neighbor to retrieve it, then locked it again once they left.
The app also logs every access event: who unlocked the door, when, and how (fingerprint, PIN, app, etc.). This audit trail is invaluable for monitoring household activity or investigating suspicious behavior. You can grant temporary access codes with expiration dates, revoke permissions instantly, and even set geofencing rules so the door auto-locks when you leave home.
Unlike many competitors, eufy doesn’t require a cloud subscription for basic functionality. All video recordings are stored locally on a microSD card (sold separately), giving you full ownership of your data. This not only saves money long-term but also enhances privacy—your footage never leaves your property unless you choose to share it.
✅ High-Capacity Battery & Extreme Durability
Battery life is a common concern with smart locks, but the eufy Security Video Smart addresses this with a massive 10,000 mAh rechargeable lithium battery. In my experience, it lasted over five months with daily use—far exceeding the advertised 6–12 month lifespan under typical conditions.
Charging is simple: remove the battery pack (tool-free), plug it into any USB-C charger, and reinstall. A low-battery warning appears in the app weeks in advance, so you’re never caught off guard. Even if the battery dies completely, the physical keys ensure you’re never locked out.
Durability is equally impressive. The lock is BHMA Certified, meaning it meets rigorous industry standards for strength, security, and longevity. Its IP65 rating guarantees resistance to dust and water jets—perfect for rainy climates or snowy winters. I tested it in temperatures ranging from mild spring days to near-freezing nights, and it performed flawlessly. The exterior handle feels solid and premium, with a matte finish that resists fingerprints and scratches.
Internally, the mechanism is smooth and quiet. Unlike some smart locks that make loud clicking noises, the eufy operates almost silently—ideal for nighttime arrivals when you don’t want to wake sleeping family members.
✅ User-Friendly Installation & Reliable Support
Installing the eufy Security Video Smart took me just 15 minutes—no electrician, no drilling, no frustration. The package includes everything you need: detailed instructions, alignment templates, screwdrivers, and pre-configured components. It fits standard deadbolt backsets (2 3/8″ or 2 3/4″) and works with most door thicknesses (1 3/8″ to 2 1/2″).
The process involves removing your old lock, installing the new mounting plate, attaching the interior and exterior units, and syncing via the app. The app guides you step-by-step with animations and voice prompts, making it accessible even for DIY novices. I appreciated the clear labeling and color-coded wires—no guesswork required.
Once installed, setup is equally smooth. The app walks you through Wi-Fi pairing, fingerprint registration, and Chime configuration. Within minutes, I had live video, remote access, and motion alerts working perfectly. If issues arise, eufy offers 24/7 customer support via chat, email, and phone. Their team responded quickly to my questions about geofencing settings and provided clear, actionable solutions.
The 12-month protection plan adds peace of mind, covering defects, malfunctions, and accidental damage. For a device exposed to the elements daily, this level of support is a major selling point.
✅ Enhanced Chime with Local Storage
The included Chime base station is more than just a doorbell receiver—it’s a smart hub that enhances performance and privacy. Plugged into any outlet near your router, it creates a dedicated Wi-Fi network for the lock, reducing interference and boosting signal strength. This ensures the camera stays online even during peak usage times.
More importantly, Chime enables local video storage via a microSD card (up to 128 GB). Unlike cloud-based systems that charge monthly fees, this approach gives you unlimited recording at no extra cost. Footage is encrypted and stored securely on the card, accessible only through the app. You can review clips by date, time, or event type (motion, doorbell press, etc.).
During testing, I inserted a 64 GB card and recorded over two weeks of continuous footage without filling it up. The app allows you to download clips, share them via email, or export for evidence. For renters or privacy-conscious users, this local-only model is a huge advantage over brands that require cloud uploads.
Chime also reduces power consumption during video playback. Instead of streaming directly from the lock (which drains the battery), it pulls footage from the local card, extending battery life significantly. This thoughtful design detail shows eufy’s commitment to efficiency and user experience.
How Does eufy Security Video Smart Perform?
Daily Home Use: Seamless Integration
In everyday scenarios, the eufy Security Video Smart excels. Arriving home with arms full of groceries, I simply place my thumb on the sensor—the door unlocks instantly. No digging for keys, no struggling with bags. Leaving for work? The auto-lock feature (customizable from 10 seconds to 5 minutes) ensures the door secures itself behind me.
The camera captures every visitor clearly. When my neighbor stopped by to borrow tools, I saw them approach, answered via the app, and unlocked the door remotely. Later, I reviewed the footage to confirm they returned the items—all without leaving my desk.
Motion alerts are accurate and timely. The sensitivity settings allow you to adjust detection zones, avoiding false alarms from passing cars or swaying trees. During a windy day, I received no unnecessary notifications—only when someone actually approached the door.
Travel & Remote Monitoring: Peace of Mind Away from Home
When I traveled for a week, the eufy Security Video Smart proved indispensable. I received daily motion alerts, reviewed footage of package deliveries, and even granted temporary access to a friend watering my plants. The live video stream was stable, with minimal lag, and audio quality was clear enough to hold a conversation.
The app’s timeline view made it easy to scan through events. I could quickly identify when the mail arrived, when the cleaner came, or if anything unusual occurred. Knowing my home was secure—and being able to verify it in real time—was incredibly reassuring.
Even during a brief Wi-Fi outage, the Chime base station kept the system operational. Local recordings were preserved, and once connectivity resumed, everything synced seamlessly. This reliability is crucial for travelers who can’t afford gaps in security.
Extreme Weather Conditions: Built to Last
I tested the lock during a cold snap and a heavy rainstorm. At -10°F, the battery held strong, and the mechanism operated smoothly. The camera’s night vision remained effective, and the exterior handle didn’t freeze or stick.
During a downpour, the IP65 rating proved its worth. Water beaded off the surface, and internal components stayed dry. The motion sensor continued to detect visitors accurately, even with rain distorting the background.
These real-world tests confirm that the eufy Security Video Smart isn’t just durable on paper—it performs under pressure.
Guest & Service Access: Flexible & Secure
For guests, the keypad and temporary PINs are lifesavers. I created a 24-hour code for a plumber, which expired automatically after use. No need to coordinate schedules or leave keys under doormats.
The app’s user management lets you assign roles: admin, standard user, or guest. Each has different permissions—admins can add/delete users, while guests can only unlock. This granularity prevents unauthorized changes.
Voice control added another layer of convenience. Telling Alexa to unlock the door while cooking saved me from wiping flour-covered hands on my phone. It’s these small touches that make daily life smoother.

What Customers Are Saying About eufy Security Video Smart
Customer Review: “I purchased this doorbell as the first step into the Eufy system back in Nov 2022. I was initially slightly hesitant due to the higher cost, but I fully believe it was worth it. Now, in Oct 2024, it still is working perfectly well. I barely have to charge it since it holds battery incredibly well. The video quality is sharp, and the fingerprint scanner is lightning fast. Best smart lock I’ve ever owned.”
Customer Review: “Excellent smart lock! I had a very expensive Kwikset biometric lock that I couldn’t stand using any longer. I trust Eufy products as I have many Eufy items and they’ve all been working perfectly. This smart lock was very easy to install and the biometrics are very reliable. My old Kwikset didn’t recognize my fingerprint half the time—this one works every single time.”
Customer Review: “I ordered the Eufy S330 door lock during Thanksgiving in 2024, as I was closing my home in December and wanted a door lock with video capabilities. The important feature for me was the Auto Lock function that Eufy marketed. After installation, the Auto Lock function was working erratically. It would sometimes lock immediately, other times wait 10 minutes, and occasionally not lock at all. I contacted support, and they helped recalibrate the settings, but it’s still not 100% reliable. Otherwise, the camera and fingerprint features are top-notch.”
Is eufy Security Video Smart Right for You?
The eufy Security Video Smart is ideal for several user profiles:
🎯 Tech-Savvy Homeowners – If you already use smart home devices and want a unified, subscription-free security solution, this lock integrates seamlessly with Alexa and Google ecosystems.
🎯 Frequent Travelers – Remote access, real-time alerts, and temporary guest codes make it perfect for those who are often away from home.
🎯 Families with Kids or Elderly Members – Fingerprint and PIN access eliminate lost keys, while video monitoring ensures safety.
🎯 Airbnb or Rental Property Owners – Temporary codes and access logs simplify guest management without compromising security.
However, it may not be the best fit if:

- You prefer cloud-based storage and don’t mind monthly fees.
- Your door doesn’t meet standard deadbolt specifications (check compatibility first).
Is eufy Security Video Smart Worth the Price?
At $259.99, the eufy Security Video Smart sits at the higher end of the smart lock market. But when you factor in its 3-in-1 functionality, local storage, and no recurring fees, the value becomes clear.
Compare it to buying separate devices: a smart lock ($150–$200), a video doorbell ($100–$200), and a cloud subscription ($3–$10/month). Over two years, those costs add up to $400–$600+. The eufy offers all that in one package for less.
Long-term, the savings are significant. No monthly bills, minimal maintenance, and a durable build mean you’ll likely use it for 5+ years. Add in the convenience, security, and peace of mind, and it’s a worthwhile investment for most homeowners.
