The Eufy S330 Video Doorbell was built with durability at its core, showcasing an impressive IP65 rating that grants it the toughness to withstand harsh weather conditions, ensuring reliability and vigilance through all seasons, whether it be rain, shine, or snow. Going beyond its role as a mere doorbell, the S330 serves as a gateway to a smarter home, seamlessly integrating with a variety of smart home ecosystems. This compatibility paves the way for simplified home automation, allowing you to craft a connected, intelligent living space with utmost ease.

False alarms are reduced by 95% through accurate dual motion detection.

Main Functions

Ultra High Resolution

At the heart of the S330 is an ultra-high-resolution sensor that offers a staggering 2K image clarity, paving the way for crystal-clear video captures. This is paired with an expansive 160-degree field of view, offering a wide-angle perspective that hardly misses any detail, be it day or night.

Night Vision

When the sun sets, the S330 does not rest. Equipped with 12 miniature IR LEDs, the doorbell offers unparalleled night vision, illuminating the darkness and ensuring security 24/7. This technology doesn’t just provide safety; it brings peace of mind to homeowners, knowing their abode is always under watchful eyes.

Two-Way Audio

Communication is taken to a whole new level with the two-way audio feature. This enables you to communicate with the person at your door from anywhere in the world, offering convenience and security wrapped in one feature. Moreover, it fosters a swift and easy way to instruct delivery personnel, greet visitors, or ward off potential threats.

AI Integration

Artificial Intelligence is no longer a thing of the future; it’s here, integrated into the S330 to offer features like facial recognition and automated alerts, bringing home security into the modern age with smart technology that learns and adapts to your safety needs.

Local Storage with eMMC Memory

Ditching the cloud storage, Eufy offers local storage with 4GB of built-in eMMC memory, ensuring all your recordings are stored safely at home. This not only protects your privacy but eliminates the need for costly subscriptions, providing a cost-effective solution to home security.

Pre-Buffered Recording

In an ingenious move, the Eufy S330 comes with pre-buffered recording, a technology that starts recording a few seconds before motion is triggered. This ensures that you get the complete picture of any event, not just a snippet from the moment the motion is detected, offering you a broader perspective and enhancing security substantially.

Easy Installation and Connectivity


With easy installation processes for both wired and battery-operated versions, the S330 integrates smoothly into existing home ecosystems. Furthermore, it boasts a 2.4GHz Wi-Fi connectivity feature, offering seamless connection to your home network without the need for additional equipment.

Battery and Wiring Options

Depending on your preference, the S330 comes in both wired and battery-powered options, providing flexibility in installation and usage. The battery-powered version promises long battery life, reducing the hassle of frequent charging, while the wired version offers continuous power supply, enhancing convenience for homeowners.
