Top 10 Best Eufy Video Doorbell in 2026 Compared
The table highlights the major differences among the 10 eufy options, including camera design, resolution, night visibility, power configuration, storage, and keyless-entry functions. It is intended as a quick orientation before reading the detailed reviews and checking the specifications of the exact bundle you are considering.
1. Eufy Video Doorbell E340 – Best Overall Eufy Video Doorbell
The eufy Security Video Doorbell E340 is the most broadly capable standalone model in this guide, earning a 4.0 rating from the supplied data. Its defining feature is a dual-camera arrangement: a front-facing camera captures people, while a downward-facing camera covers the floor and package-delivery area. That combination provides a more complete picture than a single camera focused only on a visitor's face.
Pros
- Excellent head-to-toe visibility
- Useful package-area view
- No recurring storage fee
- Flexible power installation
Cons
- Stored footage is limited
- Some chime compatibility restrictions

Image quality is listed at 2K Full HD, and the color night-vision system uses two lights with a light-capturing and processing algorithm. The stated clear nighttime viewing distance reaches up to 16 feet, or five meters. The E340 also includes 8GB of built-in eMMC storage and is described as operating without a monthly subscription, making it attractive for shoppers who prefer local recording over a cloud-dependent plan.
Installation flexibility is another strength. The quick-release rechargeable battery can be removed and exchanged in seconds, while a permanent wired installation uses a 16–24V source and keeps topping up the battery. Compatibility includes an existing mechanical chime, eufy HomeBase 2, HomeBase 3, selected eufy MiniBase Chime models, Alexa devices, and Google Voice Assistant devices. The trade-offs are that 8GB is a limited built-in capacity, and not every eufy chime is supported.
This is a strong choice for households wanting package awareness, a wide field of view, sharp daytime footage, and local storage without a recurring fee. It is especially suitable if the battery is your preferred primary power method but you may eventually want to connect the doorbell to existing wiring. Among the standalone options, the E340 balances coverage and flexibility particularly well.
A More Complete View of Visitors and Deliveries
The two cameras serve different but complementary purposes. The main camera provides a head-to-toe view of visitors, while the lower camera keeps packages and the immediate doorstep area in view, reducing blind spots when someone stands below a conventional camera's angle.
Local Storage Without a Monthly Requirement
Built-in 8GB eMMC storage allows the E340 to function without an ongoing subscription. HomeBase 2 and HomeBase 3 are also listed as compatible, giving buyers a path toward expanded local storage if their chosen setup requires more capacity.

2. Eufy E340 with HomeBase 3 – Best Local-Storage Eufy Video Doorbell
This eufy E340 bundle pairs the dual-camera doorbell with HomeBase 3 and carries a supplied rating of 4.6. The front camera concentrates on people while the downward camera fills in the floor-level view, creating the familiar E340 head-to-toe presentation. It is designed for households that want the E340's coverage paired with a substantial local-recording ecosystem.
Pros
- Large expandable storage capacity
- Detailed package-area coverage
- Strong supplied rating
- Advanced AI recognition tools
Cons
- Bundle includes a substantial base
- Cloud thumbnails use temporary storage

The key distinction is expandable storage. The system includes 16GB of built-in storage and supports expansion up to 16TB without ongoing costs, making it a better fit than the standalone version for households that want to retain more recordings locally. The listed BionicMind tools add facial recognition for filtering alerts, self-learning AI with a claimed accuracy of 99.9%, and automatically categorized security reports.
The doorbell also delivers 2K Full HD video, two-way talk, color night vision, and both wired and battery power options. Its nighttime viewing distance is stated at up to 16 feet. A detail worth noting is that thumbnail preview images for push notifications are temporarily stored in the cloud even though recordings can be saved locally, and the operating system occupies part of the built-in capacity.
The E340 with HomeBase 3 is the premium choice for buyers who prioritize long-term local storage and a broader AI-assisted monitoring system. It may be unnecessary for a single-door home with modest recording needs, but it is compelling for users who want more capacity, detailed reports, and a complete eufy security hub.
Local Recording That Can Grow
The included HomeBase 3 and support for expansion to 16TB distinguish this package from simpler doorbell bundles. Buyers who expect to record continuously or retain more important events are better positioned to take advantage of that capacity.
Smarter Alert Organization
BionicMind features are intended to make frequent notifications more manageable. Facial recognition can filter alerts, self-learning AI is described as improving accuracy, and categorized reports may help users review activity more efficiently.

3. Eufy E340 with Backup Battery – Best for Battery-Powered Operation
The battery-focused E340 bundle pairs the dual-camera doorbell with an extra quick-release rechargeable battery and a compatible chime. It has a supplied rating of 4.6, matching the HomeBase 3 bundle while offering a more direct answer to households concerned about battery availability and indoor alert delivery.
Pros
- Two-battery rotation option
- Indoor chime included
- Strong supplied rating
- Subscription-free local use
Cons
- Original Wi-Fi Chime unsupported
- Several eufy chimes excluded
We may earn a commission when you buy through this link, at no additional cost to you.
The additional battery has a stated capacity of 6,500mAh. With two quick-release batteries, users can keep one charging while the other powers the doorbell, reducing the interruption associated with waiting for a depleted pack to recharge. The E340 itself uses two cameras, 2K Full HD resolution, and color night vision with a stated clear viewing distance of up to 16 feet.
The included chime makes this bundle particularly convenient for people who want audible alerts inside the home. The supplied compatibility list includes an existing mechanical chime, HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. It explicitly does not support the original eufy Wi-Fi Chime T8020 or eufy Chime T8740 and T8742, so buyers should verify their existing equipment before ordering.
This package is a good fit for homes without straightforward doorbell wiring and for users who prefer quick battery changes. It offers a complete, practical configuration with a chime and spare battery, although the compatibility exclusions and the need to manage rechargeable packs should be considered before installation.
Battery Swaps Without Waiting
A second quick-release pack makes it possible to maintain operation while one battery charges. The result is a more flexible routine than charging the installed pack in place, especially for households that receive frequent visitor or delivery alerts.
Alerts Throughout the Home
The bundled chime offers a convenient way to hear activity indoors. It can also be paired with a mechanical chime or compatible eufy hub, provided the selected device is not one of the explicitly unsupported models.

4. Eufy E340 Renewed – Best Value E340 Configuration
The renewed eufy Security Video Doorbell E340 provides the core E340 experience in a renewed package, with a supplied rating of 4.4. It retains the dual-camera layout, 2K Full HD recording, color night vision, and flexible power options, making it a practical alternative for buyers who are comfortable purchasing a refurbished device.
Pros
- Recognizable E340 feature set
- Delivery Guard package monitoring
- No monthly storage fee
- Compatible with HomeBase S380
Cons
- Renewed condition may vary
- Wired mode requires battery
We may earn a commission when you buy through this link, at no additional cost to you.
One camera focuses on visitors, while the second captures the floor and package area. The system is listed with Delivery Guard, and its color night-vision system is described as providing a clear viewing distance of up to 16 feet. It can operate in battery mode for simpler installation or in wired mode, where the installed rechargeable battery is continually topped up by connected power.
That wired arrangement has an important requirement: the battery must remain installed, and the power source must meet the listed 16–24V and greater-than-10VA requirement. Local data storage is available without a subscription fee. The doorbell is also compatible with HomeBase S380, an existing mechanical chime, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices, while several older eufy chimes remain unsupported.
This renewed option is best for a shopper who values the E340's coverage and storage model more than the assurance associated with a new unit. Renewed products can vary in cosmetic or functional condition, so buyers should review the seller's condition details, return terms, and included components carefully before purchasing.
Core E340 Monitoring in Renewed Form
The renewed package preserves the features that define the E340: two complementary camera views, 2K Full HD imagery, color night vision, and package-area awareness. It appeals to buyers who can accept refurbished condition for a more economical route into that feature set.
Understand the Wired-Power Requirement
Unlike a purely wired installation in which the battery is unnecessary, this E340 uses connected power to keep the installed rechargeable battery topped up. The battery must remain in place, and the electrical source must satisfy the stated voltage and VA requirements.

5. Eufy Video Doorbell C31 – Best Budget Eufy Video Doorbell
The eufy Security Video Doorbell C31 is the straightforward, budget-minded option in this roundup, carrying a supplied rating of 3.9. It uses one 2K FHD camera with a 4:3 field of view, providing a clear look at visitors without the complexity of the E340's dual-camera arrangement.
Pros
- Simpler single-camera design
- Crisp 2K FHD imagery
- Quick responses and voice messages
- No subscription requirement
Cons
- No second package camera
- Hardwiring requires chime bypass
We may earn a commission when you buy through this link, at no additional cost to you.
Its visitor-response features are useful for people who are not at home. A pop-up video call appears on the phone when the bell is pressed, and the product supports quick responses and visitor voice messages. The camera is designed to retain useful detail in nighttime conditions, although it does not offer the E340's lower package-focused perspective.
Power can be supplied through the quick-release 6,500mAh rechargeable battery or by hardwiring to existing doorbell wiring. In wired mode, the battery must still be inserted, and the existing chime must be bypassed. That arrangement supports continuous 24/7 recording and five-second pre-roll for motion-activated events. Users should turn off power at the circuit breaker when replacing the battery or handling an SD card, although an SD card is not included.
The C31 is ideal for buyers who value sharp video, two-way communication, and flexible power without paying for a dual-camera system. It is also compatible with HomeBase S380, MiniBase Chime, Alexa, and Google Voice Assistant devices, although the relevant accessories are sold separately. Its limitations are its lack of a dedicated package camera and the more involved chime-bypass process for wired installation.
Simple 2K Visitor Monitoring
The C31 combines a 2K FHD sensor with a 4:3 view, a useful format for showing visitors from head to torso within the doorbell's main field of view. It is a capable choice when the primary goal is knowing who is at the door.
Useful Visitor Communication
The phone-based video call supports quick responses and voice messages, allowing a homeowner to communicate with a visitor when unable to answer immediately. This adds practical value beyond basic motion detection and recorded footage.

6. Eufy Video Smart Lock E330 – Best for Fingerprint Keyless Entry
The eufy Security Video Smart Lock E330 is not a conventional stand-alone doorbell; it combines a lock, fingerprint reader, and 2K HD camera in one front-door device. It has a supplied rating of 4.1 and stands apart from the other picks by making keyless entry and remote access management central to the experience.
Pros
- Fast fingerprint access
- Multiple unlocking alternatives
- Remote visitor notifications
- No-drilling installation
Cons
- Not a conventional doorbell
- Compatible accessories sold separately
We may earn a commission when you buy through this link, at no additional cost to you.
A 2K HD camera with an f/1.6 lens handles visitor visibility, including use after dark, while fast fingerprint recognition provides quick unlocking. Household members can also use the eufy Security app, keypad, physical keys, Alexa, or Google Voice Assistant. The lock's 10,000mAh rechargeable battery is designed to supply both locking and video functions.
Installation is described as taking about 15 minutes without drilling on most standard US deadbolt setups. Durability features include BHMA Grade 3 certification and IP65 weather resistance. Remote notifications provide visitor and activity alerts, although thumbnail preview images in push notifications are temporarily stored in the cloud. Compatibility includes eufy Chime, Chime 2, HomeBase 3, and other compatible eufy devices.
The E330 is a strong recommendation for anyone who wants a front door to function as both a security camera and an electronic lock. It is less suitable for someone who only wants a simple doorbell camera and retains mechanical keys, since the value of the device comes from combining monitoring with controlled, keyless access. Compatible accessories are separate, so those costs should be considered as part of the setup.
Monitoring and Locking in One Device
The integrated design reduces the need to choose between a video visitor camera and an electronic lock. Its camera shows who is outside while fingerprint, keypad, app, voice-assistant, and physical-key options provide several ways to enter.
Installation Designed for Common Deadbolts
The lock can often be installed over an existing standard US deadbolt without drilling, making it a practical option for homeowners who do not want a complicated retrofit. Weather resistance and Grade 3 certification support everyday exterior use.

7. Eufy Video Doorbell S330 – Best for Wired Dual-Camera Coverage
The eufy Security Video Doorbell S330 is a wired dual-camera system with a supplied rating of 4.0. It targets homeowners who already have suitable doorbell wiring and want package-oriented alerts, HDR video, and a bundled chime rather than battery convenience or local-storage expansion.
Pros
- Package arrival and pickup alerts
- Tampering notifications
- Useful pre-roll previews
- HDR-enhanced 2K video
Cons
- HomeBase is not supported
- Requires compatible doorbell wiring
We may earn a commission when you buy through this link, at no additional cost to you.
Its two cameras enhance front-door coverage and capture 2K HDR footage. Delivery Guard is designed to detect packages, send arrival and pickup reminders, and issue alerts when a package is tampered with. A three-second pre-roll preview gives users context about what happened before a motion event, which can be valuable when distinguishing a visitor from incidental movement.
The S330 operates on 16–24V, 30VA wiring and does not support HomeBase. It works with Alexa and Google Assistant for voice control and smart-home integration, and it operates without a monthly subscription fee. A chime is included in the package, which helps make the wired setup more complete for households that do not already have a compatible indoor unit.
The S330 is a good fit for a fixed installation with reliable existing wiring and a strong focus on package protection. Its lack of HomeBase support rules it out for buyers who want a larger eufy local-storage hub, while the motion-only alert behavior may be less suitable for people who want every doorbell press to trigger a particular notification category. Existing wiring should be checked before ordering.
Package Monitoring with Added Context
Delivery Guard provides package-specific arrival, pickup, and tampering notifications. The three-second pre-roll adds a brief look at preceding activity, helping users understand more about each detected event.
A Purpose-Built Wired Installation
This model is designed around reliable 16–24V, 30VA doorbell wiring and does not support HomeBase. That makes it a more constrained but potentially simpler option for buyers with established wiring and no interest in a networked base.

8. Eufy FamiLock S3 Max – Best for Palm Vein Smart-Lock Access
The eufy Security Video Smart Lock FamiLock S3 Max is a feature-heavy combination of smart lock, video doorbell, and front-door display, with a supplied rating of 4.2. Its most distinctive access feature is palm vein recognition, which is described as reading unique vein patterns and unlocking in 0.6 seconds.
Pros
- Fast palm vein recognition
- Useful rear lock display
- Broad Matter ecosystem support
- Emergency battery reserve
Cons
- Camera streams unavailable via Matter
- HomeBase 2 is unsupported
We may earn a commission when you buy through this link, at no additional cost to you.
Video monitoring comes from a 2K HD camera with an f/1.8 lens and a 150-degree head-to-toe wide-angle view. The rear lock video screen lets household members check the front-door status without opening a smartphone app, which is especially useful for children and older adults. The system also provides real-time visitor alerts, while the biometric data is described as remaining stored locally on the lock.
Power comes from a rechargeable battery offering up to four months of full functionality, backed by four AAA batteries for an additional month of essential operation during an outage. Matter support allows integration with Apple Home, Google Home, Alexa, and SmartThings. However, the supplied information notes that camera streams are not supported through Matter because of current limitations, and the eufy app is recommended for the full experience.
The FamiLock S3 Max is a compelling choice for households seeking sophisticated keyless access and a convenient in-home display. It is less suitable for users whose main requirement is a simple camera doorbell, especially if they depend on HomeBase 2. The combination of palm vein recognition, local biometric storage, a rear screen, and broad smart-home support gives it a distinctive role among the 10 products.
A New Form of Biometric Entry
Palm vein recognition uses the unique vein pattern in the user's palm as its access credential. The stated recognition time is 0.6 seconds, and the biometric data is described as being stored locally on the lock.
Check the Front Door Without an App
The rear lock video screen provides a simple way for household members to inspect the entrance. That convenience can make the product more approachable for children and older adults who may not want to use a smartphone for every visitor check.

9. Eufy E340 with HomeBase S380 – Best Complete Local-Security Bundle
This E340 package combines the dual-camera doorbell, an extra 6,500mAh quick-release battery, and HomeBase S380. Its supplied rating is 4.5, and the bundle is aimed at households that want more than a single camera: local recording infrastructure and backup power are included from the start.
Pros
- Doorbell, hub, and spare battery
- Flexible battery rotation
- Strong supplied rating
- Subscription-free local operation
Cons
- Larger combined setup
- Compatibility exclusions remain
We may earn a commission when you buy through this link, at no additional cost to you.
The doorbell provides 2K Full HD video, color night vision with a stated clear range of up to 16 feet, and separate views for people and the floor-level package area. The second battery allows one pack to remain on the doorbell while the other charges, supporting a convenient rotation routine. The complete configuration can serve as a more substantial local eufy security installation.
The bundle operates without subscription fees and can pair with an existing mechanical chime, HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. As with other E340 configurations, the original Wi-Fi Chime T8020 and Chime T8740 and T8742 are not compatible. Buyers should also consider the physical space taken by the hub and the need to keep an extra battery charged.
This is the most complete all-in-one selection for a buyer committed to the eufy ecosystem. It is a natural fit for a household that wants a dual-camera doorbell, local hub, and spare battery without assembling the system from separate components. The trade-off is a more substantial setup than a standalone doorbell and a few strict exclusions involving older chime models.
A Cohesive Local-Security Setup
Including HomeBase S380 removes the need to decide separately which local hub to use. Combined with the E340, it provides a foundation for recording and integrating compatible eufy devices within the same household system.
Backup Power in the Box
The extra 6,500mAh quick-release battery supports a rotation between two packs. This reduces downtime and complements the local hub by making the doorbell ready for regular use without waiting on a single battery to recharge.

10. Eufy E340 with Smart Display E10 – Best for Hands-Free Visitor Alerts
The E340 with Smart Display E10 has the highest supplied rating in the collection at 5.0. It combines eufy's dual-camera doorbell with an indoor display that lights up with a live feed and voice alert when someone rings the bell, unlocks the door, or is detected by the camera.
Pros
- Live feed shown on display
- Voice alerts for visitor activity
- Package-area camera view
- Subscription-free local use
Cons
- Display requires nearby power
- Hands-free features need setup
We may earn a commission when you buy through this link, at no additional cost to you.
The doorbell records in 2K Full HD and uses a front camera for people plus a downward camera for the floor and package area. Its color night-vision system is described as producing less blur than earlier iterations, with a clear nighttime viewing distance of up to 16 feet. Delivery Guard is included, helping with package monitoring, while the doorbell supports no-subscription local use.
Power is flexible: the quick-release rechargeable battery enables straightforward setup, while connected power can keep the installed battery topped up for longer operation. The Smart Display E10 provides the standout benefit of presenting visitor information inside the home without requiring someone to hold a phone or open the eufy app.
This bundle is the top choice for households that want an indoor, hands-free way to know who is at the door. It makes the most sense when the family regularly uses the display and wants both it and the doorbell in one coordinated package. The display also introduces another device that must be placed, powered, and connected, so buyers should think beyond the doorbell itself when deciding whether the bundle fits their space.
See and Hear Visitor Alerts Indoors
The Smart Display E10 automatically presents a live feed and voice alert when a relevant event occurs. This hands-free workflow is particularly useful for busy households, deliveries, and anyone who wants awareness without checking a phone.
Comprehensive Doorstep Coverage
Dual cameras capture people and the package-delivery area, while 2K Full HD resolution preserves useful detail. Color night vision extends that coverage into low-light conditions, and Delivery Guard adds package-specific awareness.

Buying Guide – How to Choose the Best Eufy Video Doorbell
The most suitable eufy video doorbell depends on whether the priority is a wide package view, reliable wired operation, expanded local recording, an indoor display, or keyless entry. Review the camera arrangement, power requirements, storage method, chime compatibility, and installation conditions before choosing a model.
Choose the Right Camera Coverage
A single camera can provide a clear 2K view of visitors, but a dual-camera system offers a more complete record of the entrance. The E340 and S330 divide their coverage between a front-facing people camera and a downward-facing package or floor camera. That second perspective is valuable when a visitor stands below the primary lens or when the main goal is to determine whether a delivery was placed, collected, or disturbed. The C31, by contrast, emphasizes a straightforward 4:3 visitor view. Choose based on the space directly below your door as well as the height at which people approach.
Understand the Power Options
Battery operation is the easiest option for homes without suitable existing wiring, and quick-release packs can make recharging less disruptive. The E340, C31, and related bundles use rechargeable batteries, while the S330 requires compatible 16–24V, 30VA wiring. Some E340 versions can use connected power to top up a battery that must remain installed. Read the electrical requirements carefully, especially if you intend to hardwire a model, and verify that the existing transformer and wiring meet the listed specifications before installation.
Compare Resolution and Night Performance
Resolution helps determine how much fine detail a camera can preserve, while nighttime performance affects how useful that detail remains after dark. Every doorbell in this list offers 2K-class imagery, but the E340 and S330 use dual-camera systems, and the E340 adds color night vision with a stated clear range of up to 16 feet. The C31 provides 2K FHD with a 4:3 field of view and nighttime visibility. Consider porch lighting as well: even a capable camera can benefit from illumination when motion occurs in very dark or reflective conditions.
Decide How Footage Is Stored
Local storage can reduce reliance on a recurring cloud subscription and keep recordings within the home ecosystem. The standard E340 includes 8GB of built-in eMMC storage, while the HomeBase 3 bundle includes 16GB and supports expansion up to 16TB. HomeBase S380 bundles and compatible hubs can also serve compatible eufy devices. The S330 operates without a monthly fee but does not support HomeBase. Note that some push-notification thumbnails are temporarily stored in the cloud even when recordings are saved locally, and the operating system uses part of the built-in capacity.
Check Chime and Smart-Home Compatibility
Before purchasing, list every indoor chime, voice assistant, and hub already in use. The E340 is compatible with a mechanical chime, HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. The original eufy Wi-Fi Chime T8020 and eufy Chime T8740 and T8742 are explicitly unsupported for relevant E340 bundles. The C31 works with HomeBase S380, MiniBase Chime, Alexa, and Google Voice Assistant, while compatible accessories are sold separately. The S330 includes a chime and supports Alexa and Google Assistant but does not support HomeBase.
Determine Whether You Need Keyless Entry
A video doorbell and a video smart lock solve different problems. The E330 combines a 2K HD camera with fingerprint unlocking, a keypad, app access, voice-assistant access, and physical keys. The FamiLock S3 Max goes further with palm vein recognition, a 150-degree doorbell view, and a rear video screen. These are compelling when contactless entry and remote access control are priorities, but they add installation and mechanical considerations that a conventional doorbell does not. Choose a smart lock only if the access-control functions justify the more integrated design.
Look Beyond the Camera
The best viewing experience may include an indoor alert device. A compatible eufy chime can announce activity in the home, while the Smart Display E10 bundle adds a live view and voice alert on a display. The E340 with backup battery includes a chime, whereas other E340 configurations may require separate accessories. Consider where an indoor display would be visible, whether it can be connected reliably, and whether family members will use the hands-free format often enough to justify the additional component.
Assess Installation and Environmental Needs
Examine the door, deadbolt, wiring, brick, trim, and available power before ordering. The E330 is described as installing in about 15 minutes without drilling on most standard US deadbolt setups and carries IP65 weather resistance. The FamiLock S3 Max uses a rechargeable battery with an AAA emergency reserve, while the E340 and C31 can use quick-release batteries. For hardwired models, check the required voltage and VA ratings, and follow local electrical guidance. Correct placement is as important as the model because the camera angle determines how much of the porch and package area is visible.
How to Use and Care for Your Eufy Video Doorbell
Install the doorbell where it can clearly show visitors and the important floor-level area without being unnecessarily exposed. Battery models can generally be mounted and configured without existing wiring, while hardwired models require compatible doorbell power and, in some cases, bypassing the existing chime. Before touching wiring, switch off the relevant circuit breaker and follow the product instructions. Position the camera at a height that produces the most useful head-to-toe or wide-angle view.
After installation, connect the doorbell to the eufy Security app, complete the account setup, adjust the camera orientation, and test the visitor alert and two-way communication. If a chime, HomeBase, Smart Display, Alexa, or Google Voice Assistant is included or purchased, pair it with the compatible model. Review motion zones, notification preferences, Delivery Guard settings, and recording behavior so that important package activity is visible without generating unnecessary interruptions.
For routine care, clean the camera lens gently and check that the doorbell is secure, the chime remains connected, and the battery is adequately charged. Keep spare quick-release batteries charged for a smooth rotation. Firmware, app, and ecosystem updates may change available features, so review the current eufy Security app and compatibility notices. Periodically confirm that local recordings are accessible, the hub has adequate storage, and any chosen notification settings still match the household's needs.
Frequently Asked Questions
What is the main difference between the E340 and the C31?
The E340 uses dual cameras: one captures visitors and the other covers the floor or package area. The C31 has a single 2K FHD camera with a 4:3 field of view, making it simpler and generally positioned as a more economical option. The E340 also offers color night vision, while both models support battery or wired configurations and local use without a subscription.
Can an Eufy video doorbell operate without a monthly subscription?
Yes, the featured doorbells are described as supporting local recording without ongoing subscription fees. The standard E340 includes 8GB of built-in storage, and the HomeBase 3 package can expand storage up to 16TB. Some push-notification thumbnails are temporarily stored in the cloud, but the product information indicates that main recordings can be saved locally.
Do I need existing doorbell wiring for an E340?
No, because the E340 can operate with its quick-release rechargeable battery. A compatible 16–24V source can instead be used for a permanent installation that continually tops up the battery. In the described wired mode, the battery must remain installed, so buyers should review the electrical requirements before selecting that configuration.
Which Eufy video doorbell has the best view of packages?
The E340 and S330 both use dual-camera systems that include a downward-facing perspective for the floor and package area. The E340 is available with several storage, battery, chime, and display bundles, while the S330 is a wired model with Delivery Guard, three-second pre-roll, and no HomeBase support. Package-focused buyers should compare those installation and recording differences.
Are all eufy chimes compatible with the E340?
No. The supplied E340 compatibility information lists a mechanical chime, HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. It explicitly excludes the original eufy Wi-Fi Chime T8020 and eufy Chime T8740 and T8742. Check the exact bundle and existing equipment before ordering.
Should I buy an Eufy video doorbell or video smart lock?
Choose a conventional E340, C31, or S330 if the main goal is visitor visibility, alerts, and package monitoring. Choose the E330 or FamiLock S3 Max when keyless entry, remote access control, and physical lock functions are equally important. Smart locks add mechanical installation considerations and different power requirements, so the camera alone should not determine the decision.
What is the difference between a chime and a Smart Display?
A compatible eufy chime provides an audible indoor alert for doorbell or camera activity. The Smart Display E10 adds a visual live feed and voice alert on an indoor screen when someone rings, unlocks the door, or is detected. The display is therefore more useful for people who want to identify activity without reaching for a smartphone.
Does the S330 work with HomeBase?
No, the supplied S330 product information explicitly states that HomeBase is not supported. It is a wired model compatible with 16–24V, 30VA wiring, includes a chime, works with Alexa and Google Assistant, and does not require a monthly subscription. Buyers interested in eufy hub integration should consider an E340 configuration with a compatible HomeBase model.
Final Thoughts on Choosing the Best Eufy Video Doorbell
The eufy Video Doorbell E340 is the strongest all-around recommendation because it combines dual-camera coverage, 2K Full HD video, color night vision, flexible power, and local storage without a monthly fee. The E340 with Smart Display E10 is the most complete indoor-alert experience, while the C31 offers a simpler and more economical route to 2K visitor monitoring.
Prioritize the feature that will solve your actual entry problem. Choose dual cameras for package awareness, a local hub for expanded recording, an indoor display for hands-free awareness, or a video smart lock for keyless entry. Confirm wiring requirements, chime compatibility, and the contents of the exact bundle before installation, because similarly named E340 packages can include different accessories.
Product configurations, firmware, accessory availability, and listing terms can change over time. Review the current product page, eufy Security app, and official compatibility information before buying. This guide is designed to narrow the field, but the best choice is the one that matches your doorway, power setup, privacy priorities, and everyday routine.
