3-in-1 Functionality

The Eufy E330 isn’t just a lock—it’s a video doorbell, smart lock, and surveillance camera in one unit. This eliminates the need for multiple separate devices and simplifies your smart home setup. You get real-time video feed, fingerprint-based access, and door monitoring—all in a single integrated design.

Five Ways to Unlock

This lock offers flexibility in unlocking methods:

1. Fingerprint Recognition
2. Eufy Security App
3. Voice Assistant (Alexa, Google Assistant)
4. Keypad PIN
5. Physical Key

This variety ensures access for everyone in the family, and for guests, even if your phone is dead or the Wi-Fi is down.

High-Capacity Battery

A 10,000 mAh rechargeable battery powers both the lock and the video features. Eufy claims this allows months of usage between charges, depending on frequency.

Easy Installation

Eufy has designed the E330 to be user-friendly. It fits most standard US and Canadian deadbolt configurations and requires no drilling or complex wiring. It’s suitable even for those without DIY experience.

Performance

Fingerprint Recognition

The fingerprint scanner is one of the fastest we’ve tested in this price category. It typically unlocks in under 0.5 seconds and supports multiple fingerprints. Setup is straightforward via the app, and users report a high success rate on the first try—critical for households with multiple members.

Video and Camera Quality

The 2K resolution camera with a f/1.6 aperture delivers impressive video clarity both day and night. Faces are distinguishable even in low light, and the infrared night vision kicks in automatically at dusk. The wide field of view ensures coverage of your porch and immediate surroundings.

In practical use, the camera performs well for:

• Identifying visitors
• Monitoring package deliveries
• Checking front yard activity

However, unlike some premium doorbell cameras, it lacks advanced AI features like package recognition or face tagging.

App Functionality

The Eufy Security app is clean, easy to navigate, and feature-rich:

• Live video feed and 2-way audio
• Event history and playback
• Remote unlocking/locking
• Fingerprint and user management
• Smart alerts with thumbnail preview

One feature we found particularly handy is auto-lock, which secures the door after a specified time. The app also allows setting temporary access codes—great for Airbnb hosts or regular visitors.

Voice Assistant Integration

Setup with Alexa and Google Assistant is smooth. You can ask your assistant to check lock status or lock the door (unlocking usually requires additional security verification).

Battery Life

Battery performance is a bit of a mixed bag. Eufy claims months of usage, but some users report needing to recharge every 1–2 months, especially in high-traffic households or colder climates. The battery is removable and charges via USB-C, which is a plus.

Estimated Battery Lifespan Table

Usage Type	Battery Duration
Low (2–4 uses/day)	Up to 5 months
Moderate (5–10 uses/day)	2–3 months
High (10+ uses/day, video events)	1–2 months
