eufy Security Video Smart Lock S330 — 3-in-1 Camera, Doorbell & Fingerprint Keyless Entry

Overview

Meet the eufy Security Video Smart Lock S330, a compact, powerful 3-in-1 device that blends a rapid fingerprint reader, a 2K HD camera, and a video doorbell into one sleek unit for your front door. The camera delivers crisp, high-contrast images in daylight and low light, capturing faces, packages, and porch activity with clear detail. The doorbell function integrates into your security routine, providing video clips and a responsive chime to greet visitors without reaching for your phone. This multi-functional entry solution blends into modern home aesthetics while keeping you confidently informed about what happens at your threshold.

Five unlocking methods provide flexible control: fingerprint recognition, the eufy Security app, Alexa or Google Voice Assistants, a numeric keypad, or traditional keys. In daily life, you can tailor entry to your routine—scan your finger after a workout, unlock from the couch with the app, or share a code with a guest or service provider. The combination of methods reduces friction while maintaining oversight and security.

Remote management and notifications

From anywhere, monitor the doorbell camera and lock status via the eufy Security app, and receive push alerts for visitors, access events, or deliveries. Temporary access codes can be issued to guests or cleaners and revoked when no longer needed. Review a detailed event log and adjust permissions without being on site, giving you greater confidence when you are away.

Durability and reliability

The S330 runs on a robust 10000 mAh battery, designed for long operation between charges. It carries BHMA certification and an IP65 rating, providing protection against rain and dust. It functions across a wide temperature range from -22°F to 158°F (-30°C to 70°C), helping it stay responsive through seasonal changes.

Storage and connectivity

Inside, an 8 GB built-in storage stores essential video and activity logs, with microSD expansion up to 128 GB for additional footage. A built-in chime adds audible confirmation, and steady Wi-Fi keeps the system connected and responsive.

Easy installation and support

The lock fits standard US and Canadian deadbolt spacings and can be installed in about 15 minutes without drilling. A 12-month protection plan and 24/7 support provide ongoing assistance, making setup and use more effortless.
