Eufy Video Smart Lock S330 Review: A Do-It-All Device with a Few Quirks
The Eufy Video Smart Lock S330 enters a market segment that’s been steadily growing – the combination smart lock, video doorbell, and security camera. While the concept of integrating these functionalities into a single device might not appeal to everyone, the S330 presents a compelling option for those seeking a streamlined, all-in-one solution for home security.
Design and Build
Right out of the box, the size of the Eufy S330 is apparent. The interior escutcheon is substantial, measuring nearly 8 inches tall and weighing over 3.5 pounds. The unit has a sturdy feel, indicating a robust build quality. Eufy opted for a matte black finish, which gives the lock a modern and understated aesthetic that should blend well with most door styles.
The package includes not only the front and rear lock components, but also an interior chime unit, a Wi-Fi bridge, and a network-attached storage (NAS) device. The inclusion of the chime and bridge is a mandatory part of the installation, so you’ll need to factor in space and placement considerations.
Features and Functionality
The Eufy S330 is packed with features. First and foremost, it functions as a complete smart lock, offering multiple entry methods: a numeric keypad, a fingerprint reader, a physical key cylinder (hidden beneath the doorbell button), and remote access via the Eufy Security app.
It also operates as a high-resolution video doorbell. A camera is positioned above the numeric keypad, and a doorbell button sits beneath it. The doorbell button illuminates blue when someone approaches, although the reliability of this feature proved to be somewhat inconsistent in testing.
Rounding out its capabilities, the S330 functions as a standard security camera, complete with a motion sensor, night vision, person detection, and two-way audio. The camera boasts a 160-degree viewing angle and a resolution of 2560 x 1920 pixels, providing clear and detailed video footage.
Installation
Despite its complexity, installing the Eufy S330 is relatively straightforward, akin to installing other complete smart locks. The exterior escutcheon is connected to a mounting plate on the inside of the door using two robust bolts. A third screw offers extra support, although it requires screwing directly into the door. Two electrical cables connect the two escutcheons, and the interior escutcheon is attached to the mounting plate with three small bolts.
The installation process should be manageable for anyone familiar with smart lock installations. Eufy’s manual provides clear instructions, although experienced users may not need to consult it extensively. The reviewer noted that tightening all bolts securely is essential to ensure proper alignment and stability.
Setup and Configuration
Configuring the Eufy S330 involves a two-step electronic process. First, the chime unit must be configured through the Eufy Security app. This involves scanning a QR code on the underside of the bridge, connecting to Wi-Fi (only 2.4GHz networks are supported), updating the firmware, and formatting a microSD card for video storage. The lock is also compatible with the Eufy HomeBase 3 NAS box, though this wasn’t tested in the review.
Once the chime is configured, the lock itself can be set up. This involves scanning another QR code on the lock and using the lock’s camera to scan a QR code displayed on the phone. A lengthy firmware update follows, after which the lock is ready for use.
The configuration process can be somewhat exhaustive due to the various options available for controlling the lock, doorbell, and camera. Setting up user PINs (4 to 8 digits) and access schedules is relatively simple. The lock supports up to 100 users and PINs and up to 50 fingerprints.
Performance
The lock operates smoothly via the app, but using the external controls presented some challenges. Entering PINs on the touchscreen was generally reliable, though occasional multiple taps were required to activate the screen. The fingerprint reader proved more problematic, often requiring multiple attempts to register a fingerprint. Improving the responsiveness and feedback of the fingerprint reader would greatly enhance the user experience.
The doorbell button is designed to illuminate blue upon detecting motion, but this functionality was erratic in the reviewer’s testing. Similarly, the "one-touch locking" feature, intended to re-lock the door by long-pressing the check button, didn’t work consistently. Fortunately, an auto-lock option provides a reliable failsafe.
The doorbell functionality performs as expected, with the lock and chime ringing when the button is pressed. However, the reviewer noted that the button’s low position and inconsistent illumination may make it less intuitive for visitors to locate. Including a placard to indicate the doorbell’s location, as some manufacturers do, could be beneficial.
Video Quality and Features
Eufy’s cameras have a good reputation, and the one included in the S330 is no exception. The 2560 x 1920 resolution and 160-degree viewing angle deliver ample video quality for doorbell camera purposes. Standard features like infrared night vision and motion detection are included.
Motion detection is customizable, allowing users to specify whether to detect all motion or only people, and to set the detection range from 3 to 20 feet. The lock can also detect loitering and when people leave the house. While these features generally worked as advertised, the reviewer experienced occasional missed motion events and inconsistent loitering detection.
Smart Home Integration and Storage
The Eufy S330 supports integration with Alexa and Google Home devices, enabling video streaming and voice control. However, it lacks support for IFTTT and Apple HomeKit.
As with other Eufy products, the S330 doesn’t require a cloud storage subscription. Users can store video clips locally on a microSD card (up to 128GB, not included) or on a Eufy HomeBase 3. Cloud storage options are available, with 30 days of storage costing $3/month or $30/year for a single camera, or $10/month or $100/year for up to 10 devices. The Smart Lock is also compatible with Eufy’s Basic Protection Plan.
Battery Life
The Eufy S330 uses a 10,000mAh rechargeable battery, which Eufy estimates will last for approximately 4 months on a full charge. The battery takes several hours to fully charge, so planning ahead is important. The lock features a USB-C port on the exterior underside, allowing for emergency power-up if the battery dies while you’re away.
Conclusion
The Eufy Video Smart Lock S330 presents a comprehensive all-in-one solution for home security. It combines a smart lock, video doorbell, and security camera into a single device. While the lock has some minor quirks, such as the inconsistent fingerprint reader and motion detection, its overall performance and feature set make it a worthwhile option for users who value convenience and integration.
The key question is whether you truly desire all these functionalities in a single device. If so, the Eufy Video Smart Lock S330 is worth considering, especially when available on sale. However, users should be aware of the potential drawbacks of combining multiple functions into one device, such as the potential for a single point of failure and the limitations of integrating with other smart home ecosystems.
