In a world where convenience and peace of mind go hand in hand, the Eufy Security Video Doorbell E340 delivers a robust front-door defense without locking you into monthly bills. This sleek, modern unit marries high-resolution imaging with intelligent processing, ensuring you always know who-or what-is on your doorstep.
Two Lenses, Zero Blind Spots
The hallmark of the Eufy Security video doorbell e340 is its dual cameras in a dual-camera architecture. A forward-facing 2 K sensor captures crystal-clear footage of visitors, while a downward-angled lens keeps parcels in sight. Together, these cameras eradicate the blind zones that plague single-lens doorbells, offering a panoramic, detail-rich perspective of your entryway.
Crystal-Clear 2 K Visitor View
Ultra-sharp 2 K resolution means facial features, clothing, and even small accessories are rendered with striking clarity. No more squinting at pixelated thumbnails-identify guests instantly, even when your phone's brightness is low.
Parcel Protector Perspective
The secondary camera watches over packages, pets, and stray deliveries stacked below eye level. You'll receive distinct video clips of both visitor and parcel zones, so you can verify that your shipment is safe without stepping outside.
Vivid Footage Day or Night
High-power sensors and advanced color night vision technology maintain natural hues long after the sun sets. Streetlights, porch lamps, or even starlight provide enough illumination for the doorbell to generate full-color clips, helping you discern clothing tones, vehicle paint, and other critical details.
A dual light system of warm and cool LEDs ensures even, balanced illumination in low-light environments.
Secure Video, Zero Subscriptions
Many video doorbells hide their true cost behind cloud plans. The E340 bucks that trend with 8 GB of built-in eMMC storage, capable of holding roughly two months of motion-triggered recordings. Your clips stay local, encrypted, and accessible only to you, eliminating recurring fees and third-party exposure.
Power It Your Way
- Long-Life Battery Setup – The 6 500 mAh rechargeable battery supports months of normal use. Pop it in, screw on the bracket, and you’re live in minutes-ideal for apartments or brick façades where wiring is tricky.

Installation Guide: Wired vs. Battery Setup
The E340's dual power options accommodate diverse installation scenarios. Understanding both approaches ensures successful deployment:
Battery-Only Installation (Renters, Brick Façades, No Existing Wiring):
- Download the Eufy Security app and create an account
- Select "Add Device" and follow the doorbell setup wizard
- Choose the mounting location at eye height (48-66 inches typically ideal)
- Use the provided bracket to align screw holes and mark with pencil
- Drill pilot holes (optional for some substrates) and install mounting bracket
- Fully charge the 6500 mAh battery (2-3 hours via USB-C)
- Snap the doorbell onto the bracket and secure
- Scan the HomeKit/QR code in the app to complete pairing
- Configure motion zones and detection sensitivity
- Test doorbell by walking past the camera; verify video and notification
Battery installation takes 15-20 minutes and requires no existing wiring. No electrician needed.
Hardwired Installation (Existing Doorbell Chime, Permanent Power):
- Turn off power to existing doorbell at your home's breaker panel
- Remove your old doorbell and photograph the existing wiring for reference
- Disconnect old doorbell wires from chime transformer connections
- Install Eufy mounting bracket in the same location as the old doorbell
- Connect the doorbell's power wires to the existing transformer leads (24V AC)
- Snap the E340 onto the bracket
- Restore power and test that the doorbell receives power
- Complete app setup, scanning HomeKit code to register the device
- Test doorbell-hardwired operation prevents battery drain
Hardwired installation takes 20-30 minutes and requires basic electrical knowledge. Consider hiring an electrician if uncomfortable with electrical work.
Hybrid Operation (Battery with Optional Hardwire Kit): The E340 also supports the optional Eufy Power Adapter (sold separately) which allows continuous charging of the battery while mounted, providing unlimited operation without hardwiring. This middle-ground option works for properties where hardwiring is impractical but continuous operation is desired.
Advanced Configuration and Customization
Maximizing E340 effectiveness requires understanding configuration options:
Motion Zone Masking: The app allows drawing custom zones to exclude specific areas (sidewalk, street, neighbor's property) from triggering alerts. This reduces false notifications from passing pedestrians or vehicles while ensuring front-door activity detection. Properly configured zones reduce alert fatigue by 70-80%.
Detection Sensitivity Levels: The app provides three sensitivity presets (Low, Medium, High) plus custom configuration. High sensitivity detects packages and small animals; Low sensitivity ignores minor movements. For busy streets, Low sensitivity prevents constant alerts; for security-focused users, High ensures no intrusions go unnoticed.
Recording Settings: Choose between "Person" only (reduces storage), "All Motion" (maximum coverage), or "Alerts Only" (minimal storage usage). "Person" mode uses on-device AI to filter irrelevant motion, saving storage and reducing review time.
Two-Way Audio Configuration: Enable audio routing to external speakers (Echo devices via Alexa) or use the doorbell's built-in speaker. Audio delay ranges from immediate to 1-2 seconds depending on network conditions. Test audio latency before relying on real-time conversations.
Quick Reply Messages: Pre-program responses like "Deliveries accepted here," "Smile, you're on camera," or "Please leave packages on the porch." Quick-reply messages send pre-recorded audio, perfect when you can't speak in real time.
Night Vision Preferences: Toggle between automatic (sensor-activated) or manual night vision modes. Color night vision activates automatically in low light; enable monochrome mode if your porch lacks lighting.
Smart Home Ecosystem Integration
The E340 extends its value through ecosystem connectivity:
Alexa Integration: Link the doorbell to Alexa through the Eufy Security skill in the Alexa app. Enable "Visitor Announcement" to trigger "Someone's at the door" audio on all Echo devices when the doorbell detects visitors. Display the live feed on Echo Show devices by saying, "Alexa, show me the front door." Create routines that trigger lights, alarms, or notifications based on doorbell activity.
Google Home Integration: Similar Alexa integration available through Google Home app. Announce visitors to Google Nest speakers and display on Google Nest Hub devices. Voice commands allow live feed access and recording review.
Automation Routines: Combine doorbell sensors with other smart home devices. Examples:
- Parcel detected → Enable porch lights for 5 minutes
- Person detected after sunset → Flash porch lights and send emergency notification
- Nobody home (geofenced) + motion detected → Trigger loud alarm
Local Network Integration: E340 connects to your home Wi-Fi (2.4 GHz only) for app control and cloud backup. Importantly, the doorbell operates locally even without internet-your motion detection, recording, and local alerts function if the internet is down.
Troubleshooting Common Issues
Understanding common problems and solutions ensures reliable operation:
Doorbell Not Connecting to Wi-Fi:
- Verify your router broadcasts 2.4 GHz (not 5 GHz only; E340 doesn't support 5 GHz)
- Restart your Wi-Fi router by unplugging for 30 seconds
- Move doorbell closer to router temporarily to test if distance is the issue
- Forget the network in the app and re-add with correct Wi-Fi password
- Factory reset the doorbell if other steps fail (hold reset button 10 seconds)
Motion Alerts Not Triggering:
- Verify app notifications are enabled in phone settings
- Check motion zone configuration-ensure detection area includes your porch
- Increase detection sensitivity to Medium or High
- Verify Internet connection is stable (test by playing online video)
- Check if app is running (background processing sometimes disables)
Poor Video Quality:
- Check Wi-Fi signal strength (move router closer or use extender if signal weak)
- Clean doorbell camera lens with soft cloth (dust/debris reduce clarity)
- Adjust brightness settings if back-lit (bright sky behind person creates darkness)
- Ensure adequate lighting for night vision (E340 needs some ambient light)
- Update firmware through the Eufy Security app settings
Battery Drains Quickly:
- Reduce detection sensitivity if receiving excessive notifications
- Disable continuous recording; use motion-triggered recording instead
- Check Wi-Fi signal strength (weak signals drain battery faster)
- Consider hardwiring if battery depletes faster than expected
- Verify night vision not set to always-on mode
Two-Way Audio Lag or Delay:
- Network latency causes audio delays-this is normal with Wi-Fi connections
- Ensure doorbell maintains strong Wi-Fi signal (above -70 dBm)
- Close other apps consuming bandwidth during conversations
- Hardwiring doesn't improve audio latency (it's network-dependent)
Storage and Privacy Insights
Understanding how the E340 handles your video data is critical for privacy-conscious users:
Local Storage Capacity: The 8 GB built-in storage holds approximately 50-60 hours of motion-triggered video (depending on compression). For normal usage (10-20 motion events daily, 30-60 seconds each), expect 1.5-2 months of storage. The app shows storage usage percentage; when full, oldest videos automatically delete.
Local vs. Cloud: Footage is stored locally on the device by default. Optional cloud backup (Eufy HomeKit Secure Video compatible on HomeKit devices) can back up video without subscription-HomeKit subscribers get 10 days of video history for free through HomeKit Secure Video.
Encryption: All stored video is encrypted with AES-256, preventing unauthorized access even if the doorbell is physically stolen.
Data Access: Only you and people you explicitly share access with through the Eufy Security app can view footage. Eufy servers process person detection AI (you can disable cloud processing for maximum privacy), but video never passes through Eufy's servers unless you enable optional cloud backup.
