The Eufy Video Doorbell E340 represents a thoughtful evolution in smart doorbell design, addressing one of the most persistent issues with conventional single-camera models: blind spots. By incorporating dual cameras into a single unit, Eufy has created a doorbell that provides complete coverage from head to toe, whilst maintaining the subscription-free approach that has made their security products increasingly popular amongst UK homeowners.
I've spent several weeks testing the E340 at my front door, and I discovered that whilst it may not be the sleekest doorbell on the market, its practical benefits and comprehensive feature set make it a compelling choice for anyone seeking robust home security without ongoing monthly costs.
Design and Installation
The Eufy Video Doorbell E340 takes a decidedly functional approach to design. At 150mm tall, 52mm wide, and 28mm deep, it's notably taller than many competitors, but I found this vertical orientation actually works in its favour. The angular black design feels robust and purposeful, though it lacks the sleek aesthetics of some premium alternatives.
Installation proved refreshingly straightforward. Unlike some smart home devices that require extensive setup procedures, the E340 can be mounted either as a battery-powered unit or connected to existing doorbell wiring. I initially opted for the wireless installation, which took roughly 20 minutes from unboxing to fully operational status.
The package includes both straight and angled mounting brackets—a thoughtful inclusion that I found particularly useful. The angled bracket proved essential for positioning the cameras optimally whilst avoiding potential issues with wall-reflected infrared lighting that can degrade night vision quality.
For those with existing doorbell wiring, the E340 supports trickle charging, which maintains battery levels whilst enabling connection to internal chimes. I tested both configurations and found the wired setup offers obvious convenience benefits, eliminating the need for periodic battery removal and charging.
Dual Camera System and Field of View
The E340's standout feature is undoubtedly its dual camera arrangement. The upper camera captures standard 2K resolution (2048 x 1536) footage, whilst the lower camera provides 1600 x 1200 resolution coverage of the area directly in front of the door.
In practice, I found this setup genuinely useful. Traditional doorbells often miss packages placed close to the wall or fail to capture the full context of what's happening at ground level. The E340's dual view eliminates these blind spots entirely, providing what feels like a complete picture of front door activity.
The transition between the two camera views creates a slight funhouse mirror effect, with visitors appearing to have elongated legs as they approach. However, this visual quirk quickly becomes negligible when you consider the practical benefits. I could clearly identify packages, see exactly where delivery drivers placed items, and monitor the complete approach path to my door.
Smart Features and Detection Capabilities
Eufy has developed several intelligent features specifically for the dual camera system. The Delivery Guard function uses the lower camera to monitor for package deliveries, automatically alerting you when items are placed in front of your door. During testing, I found this worked reliably with larger packages (roughly 25cm or more on each side) but occasionally missed smaller deliveries.
The system includes additional package-related features: Uncollected Package Alert provides daily reminders about items left outside, whilst Package Guarding can play automated responses if someone approaches a detected package. These features feel genuinely useful rather than gimmicky, particularly for households that receive frequent deliveries.
Motion detection relies on traditional PIR sensors rather than the radar-based system found in some Eufy models. Whilst this means slightly less sophisticated motion filtering, I found the detection sensitivity easily adjustable through activity zones and human-only detection modes. The facial recognition feature worked remarkably well, quickly learning to identify household members and accurately tagging them in recorded footage.
Unlike many smart home security devices, the E340 includes 8GB of onboard storage, eliminating subscription requirements for basic functionality. This storage provides approximately one month of typical recording, depending on activity levels. For extended storage, the doorbell can connect to Eufy's HomeBase system, though this requires separate purchase.
Video Quality and Performance
Image quality represents one of the E340's strongest aspects. During daylight hours, the 2K main camera produces crisp, detailed footage with excellent dynamic range. Even on my south-facing door, which experiences challenging lighting conditions throughout the day, the camera handled exposure variations admirably.
I tested the system with various lighting scenarios, from bright afternoon sun to overcast conditions, and consistently found faces clearly identifiable and details sharp throughout the frame. The lower camera, whilst operating at reduced resolution, provides perfectly adequate quality for its intended purpose of monitoring ground-level activity.
Night vision performance proved equally impressive. The E340 offers two distinct modes: traditional infrared with LED spotlights, and full-colour night vision using both upper and lower LED arrays. I found the full-colour mode particularly effective, maintaining good detail on subjects close to the door whilst the infrared mode excelled in completely dark conditions.
The combination of the built-in spotlights and infrared illumination creates excellent visibility even in challenging lighting conditions. Compared to other video doorbells I've tested, including options from Ring and Google Nest, the E340's night vision consistently produced clearer, more detailed footage.
Audio Quality and Communication
Two-way audio performance exceeded my expectations. The built-in speaker provides clear, loud audio that easily cuts through ambient noise, whilst the microphone captures voices with sufficient clarity for comfortable conversation. I found the communication lag minimal when connected to home Wi-Fi, though response times increased predictably when accessing the system remotely.
The E340 includes preset quick responses—phrases like "We'll be right there" that can be triggered with a single tap. Whilst initially sceptical of this feature, I discovered it genuinely useful for common scenarios like delivery confirmations or brief visitor acknowledgements.
Smart Home Integration and App Experience
The Eufy Security app provides comprehensive control over the E340's features. The interface feels intuitive and responsive, with video playback, settings adjustment, and notification management all easily accessible. Event filtering works well, allowing quick location of specific recordings by date, device, or event type.
Smart home integration covers Amazon Alexa and Google Assistant, enabling voice control and streaming to compatible displays. However, the E340 lacks support for Apple HomeKit, Samsung SmartThings, or IFTTT, which may disappoint users invested in these ecosystems.
Live streaming initiation typically takes 3-4 seconds from notification to active video feed—responsive enough for practical use but not quite instantaneous. The doorbell's wake-up time felt appropriate for real-world scenarios, providing sufficient responsiveness for visitor interaction.
Battery Life and Charging
Eufy estimates 6-month battery life under typical usage conditions, and my testing suggests this figure is realistic for moderate activity levels. The 6500mAh battery capacity is generous, and various power-saving options help extend operational time between charges.
However, the charging process requires complete doorbell removal, which leaves your entrance unmonitored during the 3-hour charging period. This contrasts unfavourably with systems like Ring's removable battery design, where spare batteries enable uninterrupted operation. The charging port uses USB-C, which is convenient, but the need to physically remove the entire unit remains a practical limitation.
Value and Competition
At £159.99, the E340 positions itself competitively within the premium doorbell market. This pricing includes all core functionality without ongoing subscription requirements—a significant advantage over competitors that often gate essential features behind monthly fees.
Compared to Ring's Battery Video Doorbell Plus, which offers superior motion detection through radar technology, the E340 provides better overall video coverage and eliminates subscription dependency. The Ring system excels at motion filtering but becomes expensive when factoring in cloud storage costs, particularly for single-device installations.
For UK buyers particularly conscious of ongoing costs, the E340's subscription-free operation represents genuine long-term value. When considering similar smart home security devices, such as those covered in our smart home reviews, the E340's combination of features and freedom from monthly fees stands out strongly.
Final Thoughts
The Eufy Video Doorbell E340 succeeds by solving real problems rather than simply adding features. The dual camera system addresses genuine blind spots that affect most single-camera doorbells, whilst the subscription-free model provides excellent long-term value.
I found myself consistently impressed by the video quality, intelligent detection features, and practical benefits of the dual camera arrangement. The package detection worked well enough to be genuinely useful, and the comprehensive coverage eliminated the frustration of missed deliveries or incomplete activity records.
Whilst the E340 may not offer the sleekest design or the most extensive smart home integration options, it delivers exactly what most users actually need from a video doorbell: reliable monitoring, clear footage, and intelligent alerts without ongoing costs. For anyone seeking comprehensive front door security without subscription commitments, the E340 represents an excellent choice that I can confidently recommend.
