Best for Monitoring doorstep packages and visitor activity
This dual-camera setup provides a comprehensive field of view for monitoring both doorstep packages and visitors. While the 8GB of local storage is a notable privacy benefit, prospective buyers should review eufy's specific cloud subscription terms if they intend to offload footage for remote backup.

The full review
Design and build
The E340 features a dual-lens array housed in a standard box-style plastic enclosure. Its IP65 waterproof rating suggests resistance to moderate rainfall, though users in regions with heavy snowfall or extreme temperature fluctuations should verify long-term sealing. The design offers dual installation paths: a rechargeable battery for simple surface mounting or hardwiring into a 16–24V AC system for continuous power. The quick-release mechanism simplifies battery maintenance, reducing downtime during charging cycles. Connectivity is restricted to the 2.4 GHz Wi-Fi band, which necessitates a strong signal near the entrance. The build is unobtrusive, though potential buyers should confirm that the unit fits their specific door frame dimensions prior to final mounting. Eufy includes mounting hardware intended for standard exterior walls, favoring a straightforward screw-in installation method that should be accessible to most homeowners.
Real-world performance
The primary performance advantage of the E340 is its dual-camera system, which successfully mitigates the blind spots common in single-lens doorbells. The downward-facing sensor effectively monitors package drop-offs, while the 2K primary sensor provides clear coverage of visitors. Color night vision, assisted by the dual-light system, maintains visibility up to a 16-foot range. However, users must manage expectations regarding data latency; as a Wi-Fi-connected device, real-time alerts can be delayed depending on network traffic and router proximity. While the device integrates with Alexa and Google Assistant for voice alerts, it lacks Matter compatibility, limiting deeper integration into non-proprietary smart home ecosystems. The onboard 8GB eMMC storage handles local recording cycles, but buyers should verify if this capacity meets their specific historical retention requirements, as higher activity levels will overwrite clips more frequently.
Value for money
At a price point of $119.99, the E340 offers a competitive alternative to camera systems that necessitate monthly subscription fees for feature access. The absence of mandatory cloud storage fees creates a measurable cost saving over the product's lifecycle compared to competitors that lock motion detection or history behind paywalls. While the initial hardware cost covers the baseline functionality, advanced features may require the purchase of a compatible Eufy HomeBase for enhanced AI or storage expansion. When calculating total value, consider that this device effectively serves as a standalone security camera. By avoiding ongoing subscription costs and utilizing local storage, the investment is recovered relatively quickly compared to models requiring cloud storage for full utility. It represents a sensible choice for budget-conscious users seeking high-resolution local recording without long-term service agreements.
Who should skip it
This device is not recommended for users heavily invested in a Matter-compliant smart home architecture, as the E340 lacks this interoperability. Those who require deep integration with home automation hubs outside of the Amazon or Google ecosystems should verify the specific limitations of the Eufy API, as proprietary control remains a significant restriction. Furthermore, individuals residing in homes with poor 2.4 GHz signal penetration at the front door should avoid this model unless they plan to install signal boosters, as the reliance on older Wi-Fi frequencies can cause significant connectivity dropouts. Buyers prioritizing advanced privacy protections might also wish to investigate the data encryption standards further to see if they meet specific security requirements. If you require advanced cloud backup services or cross-platform device synchronization, other ecosystems may offer more robust, albeit costlier, solutions.

Common questions
Does this doorbell require a monthly fee?
No. The device includes 8GB of local storage, allowing users to save and view video clips without a subscription. This design choice removes the recurring costs associated with cloud storage plans, providing a permanent, self-contained solution for homeowners who prefer to store data on-site.
Is the E340 compatible with Matter?
No. The E340 does not support the Matter smart home standard. Potential buyers looking for a universal, cross-ecosystem device should be aware that this unit currently functions best within the Eufy ecosystem or when connected to compatible Amazon and Google voice assistant devices for basic alert functions.
Can I use this without a HomeBase?
Yes. The E340 operates as a standalone unit using its internal 8GB eMMC storage. However, pairing it with a Eufy HomeBase 3 (S380) provides expanded storage capacity and more advanced AI detection features, which may be necessary for users with very high levels of porch activity.
Does it work on 5 GHz Wi-Fi networks?
No. The Eufy Video Doorbell E340 is restricted to 2.4 GHz Wi-Fi networks. Users should ensure their router is configured to support 2.4 GHz signals at the doorbell's location, as 5 GHz networks will not be recognized during the initial setup or operational use.
How we judge smart home devices
Rule 01
Check Matter compatibility and whether Thread requires a border router; ecosystem support and local-control features vary by device.
Rule 02
Prefer local control; cloud-only devices die with their service.
Rule 03
Read the subscription terms before buying any camera.
