Eufy Video Doorbell E340 review
Overview and dual-camera design
The Eufy Video Doorbell E340 is designed around a practical problem that single-lens doorbells do not always solve: a camera aimed at a visitor's face can miss a parcel placed directly below it. The E340 therefore uses a main front-facing 2K camera and a second downward-facing camera for the doorstep. The two views appear together in the app, allowing the owner to see both the caller and the delivery area without relying on an extremely distorted single image. It can run from its rechargeable battery or compatible existing doorbell wiring and includes local storage, so basic recording does not require a monthly cloud plan.
The E340 is physically larger than many Ring and Nest models, and its dark rectangular body is visually prominent on a narrow frame. That bulk accommodates the dual cameras, battery and lighting used for colour night footage. Installation is straightforward in battery mode, but positioning still needs care: the downward lens must actually cover the parcel zone, while the main camera should not unnecessarily capture a neighbour's doorway or large sections of pavement. The supplied wedge and app preview help, but difficult entrances may need an additional angled mount.
Video, detection and notifications
Daylight video is one of the E340's strengths. The main 2K feed provides more detail than older 1080p or 1536p doorbells, while the lower camera makes parcel events easier to verify. Built-in lights can produce colour footage in low light, with infrared available when there is insufficient illumination. Colour night vision should not be confused with daylight quality: moving faces can still blur, reflective clothing can affect exposure, and the result depends on the amount and direction of external lighting.
Eufy's on-device features include human and package detection, motion zones, Delivery Guard-style parcel monitoring, quick responses and two-way talk. HomeBase 3 can add broader storage and more advanced local AI functions, including familiar-face features within a larger Eufy system. The exact feature set varies between standalone and HomeBase operation, so buyers should check the intended configuration rather than assuming every advertised HomeBase feature is available from the doorbell alone.
Independent long-term testing generally praises the clarity, night performance and useful second view, but reports also show that remote live view can take longer to open when the doorbell has a weak Wi-Fi connection. Notification quality depends on sensitivity and activity zones. A door facing a busy footpath can still produce excessive alerts until settings are tuned, while settings that are too conservative may miss someone who approaches quickly. Package recognition is helpful but cannot guarantee that every delivery, collection or theft will be classified correctly.
Storage, power and privacy
The E340's strongest ownership advantage is local recording. The standalone product includes 8GB of local storage for event clips, with older footage overwritten as space fills. HomeBase 3 can expand capacity substantially and places storage deeper inside the property rather than in the outdoor unit. Optional cloud services exist, but they are not required for ordinary local event history. This avoids a compulsory subscription, although the higher purchase price and optional hub should still be included in the comparison.
Battery endurance depends on traffic, temperature, detection range, spotlight use and live viewing. Real-world testing can be much shorter than optimistic laboratory claims, particularly at a busy entrance. Removing the unit for charging creates downtime, so compatible wiring is attractive where available. Wiring can maintain charge and unlock some response improvements, but owners should not assume it creates uninterrupted 24/7 recording like a dedicated wired security camera. The exact transformer requirements and chime compatibility must be checked before connecting existing wiring.
Local storage reduces routine cloud dependence, but a connected doorbell still uses online services for app access and notifications. Eufy faced substantial criticism in 2022 over security and cloud-handling claims; the company says it redesigned protections and now emphasises local processing. Buyers should treat privacy as an ongoing configuration issue rather than a one-time brand promise: use unique credentials, enable two-factor authentication, install firmware updates, restrict shared users and review whether thumbnail notifications temporarily use cloud services. Privacy zones should limit capture beyond the household boundary.
Value and verdict
The Eufy E340 is the strongest option in this MainBuyer group for buyers who want direct parcel coverage and local recording without a mandatory subscription. Its main advantages are the genuinely useful second camera, clear 2K main feed, included storage, flexible power and compatibility with a larger HomeBase system. Its drawbacks are a bulky body, variable battery intervals, an app that can require careful tuning and an ownership decision about whether to trust Eufy's revised privacy approach.
It costs more upfront than the Tapo D235, but the dual-camera design is easier to justify at a doorstep where packages are often left directly below the bell. Ring offers a more polished Alexa and cloud experience but adds recurring fees; Nest provides excellent free object alerts but much shorter free history; Tapo is the value choice with local microSD storage. For a household that wants subscription-light security and can position the two cameras properly, the E340 is a compelling long-term buy.
