🔍 Why We Picked It

The eufy Security Video Doorbell E340 stands out in a crowded market by tackling the two biggest frustrations of modern smart doorbells: blind spots and mandatory monthly subscription fees. Its dual-camera configuration combines a primary 2K front-facing lens for visitors with a dedicated 1080p downward-facing lens for package deliveries, giving homeowners a separate view of the doorstep.

Crucially, the E340 includes 8GB of built-in local storage, allowing homeowners to save, review, and manage video clips without a mandatory cloud subscription plan. Local storage should not be confused with completely cloud-free operation: rich notifications with image previews use cloud processing, and eufy offers optional paid cloud backup services. Verify model eligibility and regional plan terms before subscribing; cloud processing does not by itself establish a subscription requirement. Eufy product documentation and cloud backup guidance.

Users should also consider eufy's security history. Following the 2022 disclosure of insecure streams, the New York Attorney General announced a $450,000 settlement on January 28, 2025 with three distributors of eufy products. The investigation found weaknesses in encryption and stream authentication; the settlement required stronger safeguards. This historical finding is not an independent assessment of the E340's current firmware. Official settlement announcement.

For buyers seeking dual-lens coverage without a mandatory monthly recording bill, the E340 merits consideration alongside its ecosystem and privacy limitations.

🟢 Pros

• Dual-Camera Coverage: Secondary 1080p lens provides a dedicated view of packages at the doorstep.
• Subscription-Free Local Storage: 8GB of internal storage means no mandatory recurring subscription for local video history.
• Alexa and Google Assistant Integration: Supports these platforms; audit the exact features on the target smart display rather than assuming parity.
• Flexible Installation: Can use the removable battery or compatible doorbell wiring to top it up; the battery stays installed in wired mode.

🔴 Cons

• No Native Apple HomeKit Support: The E340 does not natively integrate into Apple's ecosystem.
• Historical Security Caveats: Past data handling practices and the 2025 settlement deserve consideration alongside current privacy settings.
• Cloud Processing for Rich Alerts: Thumbnail previews use cloud infrastructure. Local recording does not make all services local-only.
• No 5 GHz Wi-Fi: Requires an available 2.4 GHz network.

📡 Delivery Detection & Notification Performance Tests

Storage context: The supplied estimate is approximately 300 MB per day for 20 clips per day at 2K resolution. Dividing 8 GB by 300 MB gives about 26.7 days before accounting for reserved capacity and overhead. A 24–25 day rolling-history estimate may be consistent with that usage, but actual retention varies with clip duration, compression, activity, settings, and usable capacity; it is not an exact guarantee.

❓ Frequently Asked Questions

Does the eufy E340 truly require zero monthly fees?

For local recording and playback, a cloud subscription is not mandatory. The doorbell includes 8GB of local storage. Optional cloud backup services may incur fees; check eligibility and current terms. Thumbnail alerts use cloud processing, which should not be conflated with a paid-plan requirement. Eufy recording guidance.

Is the downward-facing camera high definition?

Yes. Eufy labels the lower package camera 1080p and lists a 1600 × 1200 image size. The front-facing camera is listed as 2K. Shipping-label readability still depends on lighting, placement, distance, and the results of actual testing.
