An Eufy video doorbell can add useful front-door awareness without requiring a full home-security system, but the right model depends on how you want to power it, store recordings, and monitor visitors. The most important considerations include image quality, field of view, night performance, battery convenience, local storage, and smart-home compatibility.

This guide compares ten eufy-branded options, including conventional E340 and C31 video doorbells, the wired S330, two E340 bundles, and related E330 and FamiLock S3 Max smart locks with integrated cameras. Features were evaluated using the supplied specifications, with particular attention to dual-camera coverage, 2K video, color night vision, pre-roll, local storage, wiring requirements, and included accessories.

The entries reveal that eufy offers several ways to approach front-door security, from a straightforward wired model to battery-powered bundles with extra power and local-storage hubs. Each review explains the strongest reasons to consider the product, along with compatibility limitations and practical trade-offs. Prices and bundle contents can change, so readers should confirm the current listing before purchasing.

1. eufy E340 – Flexible Dual-Camera Value

eufy Security Video Doorbell E340, Dual Cameras, 2K FHD4.0Editor scoreCheck price on Amazon
eufy E340
Dual front and floor cameras
2K Full HD capture
8GB built-in local storage
Battery or wired operation

The eufy Security Video Doorbell E340 combines two cameras, 2K Full HD recording, color night vision, and flexible power options in one of the more capable conventional doorbells listed here. Its 4.0 rating reflects a strong core feature set, although the lower score than several bundles suggests that customer satisfaction may depend heavily on installation, storage expectations, and accessory compatibility.

Pros

  • Useful package-focused second camera
  • No recurring storage fee
  • Flexible installation options
  • Swappable rechargeable battery
  • Color night vision

Cons

  • Smart-home chime compatibility varies
  • Included storage is limited

Its most distinctive advantage is the dual-camera arrangement. A forward-facing camera captures the visitor and surrounding area, while the downward camera fills in the floor directly in front of the entrance. That combination is especially useful for monitoring packages or activity near the threshold. The camera also uses a dual-light system and processing algorithm intended to reduce blur, with a stated clear nighttime viewing distance of up to 16 feet.

Storage is handled through 8GB of built-in eMMC, allowing local recording without a recurring subscription. The tradeoff is that 8GB is not much for a security camera that may record frequently, and the storage cannot necessarily be expanded without adding compatible equipment. A wired installation to a 16–24V source can keep the battery topped up, but households wanting a self-contained, removable-battery setup may find that the most convenient approach.

This is a strong choice for someone who wants more coverage than a single-camera doorbell and values local storage without a monthly charge. It is less appropriate if you need a particular older chime, require the S330's pre-roll behavior, or want a package that includes a backup battery or hub. For most users, though, the E340's dual views and installation flexibility make it an attainable, broadly useful choice.

Coverage Where Deliveries Arrive

The downward-facing camera gives the E340 a practical advantage over single-camera models. It is designed to show packages and floor-level activity while the main camera remains focused on people approaching the door.

Local Storage Without a Subscription

Built-in 8GB eMMC supports local recording without ongoing cloud fees. Users who need longer retention or greater capacity should verify compatible expansion options before installation.

2. eufy E340 HomeBase 3 – Complete Local-Security Bundle

eufy Security Video Doorbell E340 (with HomeBase 3), 2K Full HD Dual Cameras&Head-to-Toe View,Wired/Battery Power,Delivery Guard,Color Night Vision,Two-Way Talk, Local Expandable Storage up to 16TB4.6Editor scoreCheck price on Amazon
eufy E340 HomeBase 3
Dual camera system
2K Full HD capture
Up to 16TB local storage
HomeBase 3 included

This E340 bundle stands out as the most complete conventional video doorbell in the guide because it combines the doorbell with HomeBase 3. It carries a 4.6 rating and offers dual cameras, 2K Full HD imagery, color night vision, two-way communication, and local storage expandable to as much as 16TB. That combination makes it well suited to households that want more retention and centralized eufy management.

Pros

  • Generous expandable local storage
  • Advanced BionicMind features
  • Flexible wired or battery setup
  • Clear color night vision
  • Focused visitor and floor views

Cons

  • Bundle complexity exceeds standalone model
  • Some features require eufy ecosystem

We may earn a commission when you buy through this link, at no additional cost to you.

The two-camera design maintains the E340's useful division of labor. One view focuses on people at the door, while the downward-facing camera covers the floor and package zone. Color night vision extends that coverage into nighttime conditions, and the stated clear viewing distance reaches 16 feet. The bundle also supports flexible installation, with either a rechargeable battery or a 16–24V wired supply capable of keeping the battery topped up.

HomeBase 3 is the major addition. Its local storage can be expanded up to 16TB, which is a major advantage over relying only on the doorbell's smaller built-in memory. The supplied information also highlights BionicMind capabilities, including facial-recognition-based alert filtering, self-learning AI, and categorized security reports. These are valuable for users who want structured intelligence rather than a basic motion feed, although they make the eufy ecosystem more relevant.

Choose this package if you want a complete front-door security setup and plan to manage recordings locally. It is less attractive for a simple single-doorbell installation, especially when another eufy hub is already present or when the listed bundle no longer represents the best current configuration. Even so, the 4.6 rating, extensive storage ceiling, and dual-camera hardware make it the strongest all-around package for serious local recording.

Storage for Long-Term Recording

The included HomeBase 3 changes the E340 from a compact standalone device into a more capable local-security system. Expandable storage up to 16TB reduces the need for routine manual deletion and supports a broader recording history.

Smarter Visitor Alerts

BionicMind adds facial-recognition filtering, self-learning accuracy, and categorized reports. These tools are most useful for households that want relevant notifications and a more structured record of front-door activity.

3. eufy E340 Extra Battery – Convenient Battery Backup

eufy E340 Extra Battery
Dual camera system
2K Full HD capture
Extra 6,500mAh battery
Compatible chime included

The E340 Extra Battery bundle is built around a straightforward proposition: use one rechargeable battery in the doorbell and keep the second ready for fast replacement. With a 4.6 rating, it offers the same core camera hardware as other E340 configurations while adding an extra 6,500mAh battery and a compatible chime. That makes it particularly useful for renters or newer homeowners who want simple installation without running new wiring.

Pros

  • Two-battery rotation convenience
  • Quick-release battery design
  • Included compatible chime
  • No subscription requirement
  • Strong 2K dual-camera coverage

Cons

  • Older chime models excluded
  • Battery charging still requires planning

We may earn a commission when you buy through this link, at no additional cost to you.

Both cameras contribute meaningfully to the experience. The front camera monitors visitors, and the lower camera captures the area directly in front of the door. Together they support a head-to-toe view in 2K Full HD. The stated color night vision system uses dual lights and an advanced processing algorithm to reduce blur, with a clear nighttime range of up to 16 feet.

The quick-release design is the bundle's standout practical feature. Rather than removing the entire doorbell while its battery charges, a user can swap in the backup and return the depleted pack to its charger. A compatible chime extends the audible alert inside the home, while local recording removes the need for a monthly subscription. The listed compatibility includes eufy HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa, and Google Voice Assistant devices.

Compatibility deserves attention because this bundle is not compatible with the original eufy Wi-Fi Chime T8020 or eufy Chime T8740/T8742. Buyers should therefore check what chime they already own rather than assuming every eufy accessory will work. For someone prioritizing battery convenience, an included chime, and local recording, this is one of the strongest E340 bundles in the guide.

Fast Battery Swaps

The second quick-release battery reduces the disruption associated with recharging. One pack can remain in service while the other is charging, making planned maintenance considerably easier.

Alerts Inside the Home

The included compatible chime gives visitors a way to ring in beyond the phone and camera system. Existing owners should verify compatibility because several older eufy chime models are explicitly excluded.

4. eufy E340 Renewed – Proven Core Model Value

The renewed E340 brings the familiar dual-camera and 2K Full HD platform to buyers seeking a previously owned option. Its 4.4 rating is solid, and the listed features cover the elements that make the current E340 attractive: a front visitor camera, a downward package camera, color night vision, local storage, and flexible wired or battery operation.

Pros

  • Full core E340 feature set
  • Flexible power configuration
  • Useful dual-camera coverage
  • Local storage without fees
  • Color night vision

Cons

  • Renewed condition may affect appearance
  • Battery may require replacement sooner

The forward camera concentrates on people, while the lower camera fills in the floor area. The dual-light night-vision system is specified to deliver a clear viewing distance of up to 16 feet. Color night vision is particularly useful when a porch light does not provide even illumination, while 2K resolution gives users more detail than a standard definition doorbell feed.

Installation can be battery-only or wired. In wired mode, the quick-release battery must remain installed and is charged by a 16–24V power source, so the wiring itself does not fully replace the battery. That design allows the same hardware to move between power arrangements, but buyers should understand the distinction. The product can connect with an existing mechanical chime, eufy HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa, and Google Voice Assistant devices.

A renewed product is most compelling for someone comfortable with refurbished hardware and seeking to reduce spending while retaining current-generation features. The principal uncertainty is cosmetic or battery condition, which may not match a new unit, particularly if the quick-release pack is near the end of its service life. It is best for value-conscious buyers who check the return coverage and battery condition carefully.

Current-Generation Coverage

A renewed listing can still provide the full E340 imaging design, including the two complementary views and color night vision. This makes it a practical alternative to buying an older single-camera doorbell.

Power Flexibility

The same unit supports removable-battery convenience or a wired setup in which the battery stays installed and remains topped up. Homes with different wiring conditions can use one model for either approach.

5. eufy C31 – Straightforward Single-Camera Option

eufy C31
Single 2K FHD camera
Four-by-three field view
6,500mAh quick-release battery
Five-second pre-roll

The eufy C31 is the guide's simplest traditional video doorbell. It uses one 2K FHD camera with a 4:3 field of view instead of the E340's dual-camera arrangement. Its 3.9 rating is the lowest among the listed options, but the specification reflects a focused product for buyers who value simplicity, familiar entry alerts, and flexible installation over package-specific coverage.

Pros

  • Simple single-camera design
  • 2K visitor detail
  • Quick-response messaging
  • Hardwired pre-roll option
  • No subscription required

Cons

  • No downward package camera
  • Wired installation requires chime bypass

We may earn a commission when you buy through this link, at no additional cost to you.

The 4:3 composition is designed to preserve more of the doorway and visitor area than a very narrow vertical feed. When someone rings, the eufy Security app can present a pop-up video call. Quick responses and visitor voice messages offer ways to communicate when the homeowner is away, adding a practical layer beyond simply receiving a motion alert.

The C31 accepts a quick-release 6,500mAh rechargeable battery for flexible installation. It can also be hardwired to existing doorbell wiring, but the battery must remain inserted and the existing chime must be bypassed. That hardwired arrangement enables continuous 24/7 recording and a five-second pre-roll for motion events, giving it one of the more useful event previews in the group.

Choose the C31 if you need a straightforward doorbell camera, want quick visitor communication, and prefer the security of continuous recording without managing battery swaps. It is less suitable when a separate downward camera is important for package visibility. The need to bypass an existing chime in a hardwired installation also makes it less convenient for homeowners reluctant to alter their current setup.

Useful Visitor Communication

Pop-up video calls, quick responses, and voice messages make the C31 more interactive than a basic motion-alert camera. These functions are helpful when a visitor arrives while nobody is available to answer immediately.

Pre-Roll for Hardwired Use

Hardwiring enables continuous recording and a five-second pre-roll for motion events. The pre-roll preserves context that a recording beginning only after motion is detected could otherwise miss.

6. eufy E330 Smart Lock – Video and Keyless Entry

eufy E330 Smart Lock
Integrated 2K HD camera
Fingerprint keyless entry
10,000mAh rechargeable battery
BHMA Grade 3

The E330 Video Smart Lock combines a 2K HD camera, fingerprint reader, keypad, physical key option, and smart access control in a single front-door device. Its 4.1 rating reflects a versatile alternative for people who want to monitor visitors and remove the need for traditional keys without installing a separate video doorbell.

Pros

  • Doorbell and lock combined
  • Multiple entry methods
  • Large rechargeable battery
  • No-drilling installation
  • IP65 weather resistance

Cons

  • Requires compatible deadbolt setup
  • Accessory devices sold separately

We may earn a commission when you buy through this link, at no additional cost to you.

The integrated camera uses an f/1.6 lens, and the lock supports fast fingerprint recognition for routine family entry. The eufy Security app, Alexa, Google Voice Assistant, keypad, and physical keys offer several alternatives, making the device useful for family members, guests, and visitors who need remote permission rather than a saved fingerprint.

Power comes from a 10,000mAh rechargeable battery intended to support both locking and video functions. Installation is listed as taking about 15 minutes without drilling on most standard U.S. deadbolt setups. The lock has BHMA Grade 3 certification and IP65 weather resistance, which are meaningful considerations for an exterior device exposed to daily use and changing weather.

This is a compelling choice when a smart lock can replace both the deadbolt and a stand-alone doorbell. It is less suitable if the door has an unusual deadbolt, if existing doorbell wiring is already in place, or if you want the E340's separate package camera. Compatible eufy cameras, doorbells, chimes, and HomeBase 3 can expand the setup, but those accessories are sold separately.

Several Ways to Enter

Fingerprint recognition provides quick access for regular users, while the app, keypad, voice assistants, and physical key provide alternatives for different situations. This flexibility helps accommodate family members and temporary visitors.

Camera and Lock in One Device

Combining a 2K camera with a full smart lock reduces the need for separate front-door hardware. The result is especially useful for consumers seeking integrated access and visitor awareness.

7. eufy S330 Wired – Fixed-Power Dual-Camera Security

eufy Security Video Doorbell (Wired) S330 with Chime, Dual Cam, Delivery Guard, Security Camera, 2K with HDR, No Monthly Fee, 16-24V, 30VA, homebase NOT Supported, Motion Only Alert4.0Editor scoreCheck price on Amazon

The wired S330 is a fixed-power alternative for homes with compatible doorbell wiring. It combines two cameras with 2K HDR recording, Delivery Guard package detection, and a three-second pre-roll preview. Its 4.0 rating makes it a practical choice for users who prefer continuous wired operation and are not interested in managing a rechargeable battery.

Pros

  • No battery charging routine
  • Strong dual-camera coverage
  • Useful package detection
  • HDR image capture
  • Chime included

Cons

  • HomeBase unsupported
  • Wiring installation required

We may earn a commission when you buy through this link, at no additional cost to you.

The dual cameras expand coverage beyond the primary visitor image, while HDR helps preserve detail in scenes with bright and dark areas. Delivery Guard can recognize package arrival, send arrival and pickup reminders, and alert when a package appears to be disturbed. These package functions give the S330 a useful role beyond simply showing who rang the bell.

Pre-roll is particularly valuable because it preserves a short sequence before a motion event, providing context for events that might otherwise begin too late. The bundle includes a chime and supports Alexa and Google Assistant for voice control and smart-home integration. It does not require a monthly subscription, and the specified electrical requirement is 16–24V and 30VA.

The major limitation is ecosystem rigidity. HomeBase is not supported, so users seeking a large expandable local archive through a eufy hub should look elsewhere. Motion-only alerts may also be less comprehensive than systems that provide a broader range of event categories. For a homeowner with the correct wiring who wants a dual-camera, no-subscription doorbell, however, the S330 offers a straightforward and dependable configuration.

Package Activity Awareness

Delivery Guard provides package arrival and pickup reminders along with tampering alerts. It turns the doorbell into a more useful monitoring point for households that frequently receive deliveries.

Context Before Motion

The three-second pre-roll shows activity that occurred before a motion event. That context can make recorded events easier to understand and reduces the chance that a short recording begins after the important action.

8. eufy FamiLock S3 Max – Advanced Biometric Lock

eufy FamiLock S3 Max
Integrated 2K HD camera
Palm vein recognition
150-degree wide-angle view
Matter and Apple Home support

The FamiLock S3 Max is the most technically advanced locking product in the guide, using palm vein recognition instead of a conventional fingerprint sensor. It unlocks in a stated 0.6 seconds, stores biometric data locally, and combines that access system with a 2K HD camera, smart-lock functions, and a 150-degree head-to-toe view.

Pros

  • Fast palm vein recognition
  • Rear interior video screen
  • Wide head-to-toe camera view
  • Local biometric data storage
  • Strong backup power design

Cons

  • Higher-complexity smart lock
  • Camera streams unavailable through Matter

We may earn a commission when you buy through this link, at no additional cost to you.

The palm vein system reads the unique vein pattern in the user's hand and is presented as forgery resistant. The 2K camera uses an f/1.8 lens for low-light visibility, while the wide field of view is intended to reduce blind spots around packages and visitors. A rear video screen lets people inside check the front-door status without opening the eufy app, which may be particularly useful for children and older residents.

Power redundancy is a notable feature. The rechargeable battery can provide up to four months of full functionality, while four AAA batteries supply an additional month of essential operation during an outage. Matter support allows integration with Apple Home, Google Home, Alexa, and SmartThings. The eufy app remains necessary for the complete experience because camera streaming is not supported through Matter under current limitations.

This is best suited to a household that wants a sophisticated smart lock and local biometric access rather than a conventional doorbell. The rear display adds family convenience, and the wide camera can perform many doorbell-monitoring tasks. The tradeoff is complexity: buyers must use the eufy app for full features, and the product is not compatible with HomeBase 2, although Matter works with HomeBase 3.

Palm Vein Access

The lock recognizes a hand's vein pattern and is specified to unlock in 0.6 seconds. Because biometric information remains stored locally, the system is designed to keep sensitive access data under the user's control.

In-Home Door Status

The rear lock video screen provides a straightforward way to check who is outside without a smartphone. It reduces dependence on the app for routine household visibility.

9. eufy E340 HomeBase S380 – Hub-Ready Battery Bundle

Two 6,500mAh batteries
HomeBase S380 included

This E340 package combines the standard dual-camera doorbell, an extra 6,500mAh quick-release battery, and HomeBase S380. The 4.5 rating reflects a well-rounded bundle that covers three common needs: local event storage, uninterrupted battery operation, and detailed 2K coverage with color night vision.

Pros

  • Hub and two batteries included
  • Flexible battery replacement
  • Local storage without fees
  • Strong dual-camera coverage
  • Color night vision

Cons

  • Redundant for single-door setups
  • Compatibility must be checked carefully

We may earn a commission when you buy through this link, at no additional cost to you.

The battery arrangement is designed for straightforward rotation. One pack operates the doorbell while another is charged, reducing the chance of an extended period without service. The cameras cover different parts of the entrance, with the front-facing lens focused on visitors and the lower lens directed toward packages and the floor.

The included HomeBase S380 serves as the local hub. This makes the bundle suitable for consumers who want recordings kept through the eufy ecosystem rather than depending solely on the doorbell's built-in capacity. Compatible accessories include eufy HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa, and Google Voice Assistant devices, while the older T8020 and T8740/T8742 chimes are not supported.

Choose this configuration if you are starting a broader eufy security setup and want the hub, spare battery, and dual-camera doorbell together. It may be excessive for a single entrance where phone-only viewing is enough. The strongest use case is a battery-oriented household that values local recording, planned battery swaps, and detailed visitor monitoring without recurring storage fees.

Hub-Based Local Recording

HomeBase S380 provides a central location for compatible eufy security devices and supports the bundle's no-subscription approach. It is a sensible foundation for users planning to add more cameras or locks later.

Two-Battery Operation

The extra quick-release pack allows charging to happen outside the doorbell. Users can maintain front-door coverage by swapping packs rather than taking the entire unit out of service.

10. eufy E340 Smart Display E10 – Hands-Free Home Alerts

eufy E340 Smart Display E10

Smart Display E10 included

The E340 Smart Display E10 bundle is the most complete premium package in the guide because it adds an indoor display to an already capable dual-camera doorbell. Its 5.0 rating is the highest listed, and the defining feature is automatic, hands-free notification: the display lights up with a live feed and voice alert when someone rings, unlocks the door, or is detected by the camera.

Pros

  • Automatic live visitor display
  • Voice and hands-free alerts
  • Detailed dual-camera coverage
  • Color night vision
  • Flexible power modes

Cons

  • Display adds another device
  • Battery mode still needs charging

We may earn a commission when you buy through this link, at no additional cost to you.

The doorbell retains the E340's strongest imaging features. One camera focuses on people while the downward-facing camera covers packages and floor-level activity. Both feed into 2K Full HD recordings, and the dual-light system with color night vision is specified to reduce blur and provide a clear nighttime viewing distance of up to 16 feet.

Installation remains flexible. Battery mode offers the simplest setup, while wired mode keeps the installed battery topped up through a suitable power source. This makes the bundle appropriate for both renters and homeowners with existing doorbell wiring. Local storage is available without a subscription fee, allowing users to avoid recurring costs for camera recording.

Choose this package when someone wants to know immediately who is at the door without reaching for a phone. It is especially useful in kitchens, offices, or other rooms where an indoor display is convenient. The tradeoff is added hardware and another screen in the home. Battery-powered users must also maintain the charging routine, and those wanting a wide field of view may find the E330 or FamiLock S3 Max more suitable.

Alerts Without Reaching for a Phone

The Smart Display E10 automatically presents a live feed and voice alert for rings, unlocks, and camera detections. It creates a more visible and immediate way to monitor the front door.

Detailed Coverage Day and Night

The E340's separate visitor and downward cameras cover complementary areas of the entrance. Color night vision and 2K resolution make those views more useful across changing lighting conditions.

Buying Guide – How to Choose the Best Eufy Video Doorbell

The right eufy video doorbell depends on installation conditions, camera coverage, recording preferences, and the accessories you already own. Comparing these factors before buying can prevent unnecessary accessories and help ensure that the device works with your home's wiring, smartphone, and smart-home setup.

Dual Cameras Versus a Single View

Dual-camera models divide the doorbell's job between a forward-facing visitor camera and a downward-facing package or floor camera. This arrangement gives a more complete view of the entrance and is especially useful for delivery monitoring. A single-camera model such as the C31 is simpler and may be sufficient when your priority is seeing and communicating with people at the door. Consider the geometry of your porch, the distance between the door and package drop zone, and whether you want to identify a visitor or monitor objects near the threshold.

Image Resolution and Night Vision

The E340, C31, S330, E330, and FamiLock S3 Max all specify 2K-class imagery, but resolution alone does not determine image quality. The E340 family's color night vision uses a dual-light system and processing algorithm, while the S330 uses 2K HDR. Pay attention to the stated viewing distance as well: the E340 is specified to remain clear for up to 16 feet, or 5 meters. Actual results will vary with porch lighting, reflective surfaces, weather, and the camera's position.

Battery Versus Wired Installation

Battery operation is easiest for renters and homes without compatible wiring. Quick-release packs can be swapped for charging, although you will need a way to keep a charged pack ready. Wired operation can provide continuous availability, and most E340 variants can also use the battery as a top-up source. The S330 is specifically wired and requires 16–24V at 30VA. The C31's hardwired mode requires bypassing the existing chime, so inspect the wiring before selecting a model.

Local Storage and Subscription Needs

Local recording is a central advantage of the E340 line, which is specified without a recurring subscription. The standalone E340 includes 8GB of eMMC, while the HomeBase packages offer a more scalable local-storage path. If you want weeks or months of searchable recordings, prioritize a compatible hub and its supported capacity rather than assuming the doorbell's built-in memory is sufficient. Also consider whether temporary cloud storage of notification thumbnails affects your privacy expectations.

Package Monitoring Features

Package-focused monitoring can include a downward camera, Delivery Guard alerts, arrival and pickup reminders, and tamper warnings. The E340's lower camera provides visual coverage, while the S330 explicitly emphasizes Delivery Guard and package notifications. These features are useful for households receiving frequent deliveries, but they do not replace a proper exterior camera if your goal is broad property surveillance. Check the precise package-detection features included in the specific bundle.

Smart-Home and Chime Compatibility

Most options work with the eufy Security app, Alexa, or Google Voice Assistant, while specific bundles include a chime. Compatibility is not universal: the E340 bundles with the listed extra battery exclude the original eufy Wi-Fi Chime T8020 and eufy Chime T8740/T8742. The S330 does not support HomeBase. The FamiLock S3 Max supports Matter but cannot stream camera feeds through Matter under current limitations. Make a list of your existing hub, chime, app, and voice-assistant setup before ordering.

Doorbell or Integrated Smart Lock

The E330 and FamiLock S3 Max are smart locks with integrated cameras rather than ordinary stand-alone doorbells. They are compelling when keyless entry, fingerprint or palm vein access, and visitor awareness should be combined in one device. A conventional E340 or C31 is generally easier to add to an existing door without replacing the deadbolt. Consider door hardware, installation complexity, entry methods, interior access needs, and how important a rear display is to your household.

Power Redundancy and Ongoing Maintenance

A spare battery is valuable for any battery-powered installation because it allows one pack to charge while the other remains in service. The E340 extra-battery bundles include a second 6,500mAh pack. The FamiLock S3 Max takes a different approach with a rechargeable battery plus four AAA emergency cells. Whichever model you choose, establish a charging routine and check battery health periodically. For critical monitoring, wired power or a redundant battery design is generally easier to maintain.

How to Use and Care for Your Eufy Video Doorbell

Begin by identifying the installation path. For a battery setup, mount the unit where you can clearly see visitors and the important package area, then insert the quick-release battery and connect it through the eufy Security app. For a wired installation, switch off power at the circuit breaker, follow the device's wiring instructions, and confirm the required voltage before connecting anything. The C31 requires the existing chime to be bypassed for hardwired operation, while E340 wired mode requires the battery to remain installed so it can be topped up.

Once operating, adjust the camera position to cover the doorway, floor, and package drop zone without capturing unnecessary private areas. Use the app to define suitable motion areas, enable the alerts and pre-roll behavior that match your routine, and test night illumination after dark. If a chime is included or supported, place it where it can be heard throughout the home. For a smart lock, register fingerprints or palm veins carefully and retain a physical key as a backup until every household member is comfortable with access.

For care, clean the lens gently and check that the protective cover or visor is not obscured by dirt, condensation, insects, or spiderwebs. Monitor battery condition and recharge spare packs before the installed pack becomes depleted. Keep the eufy app and firmware current, confirm that local storage or hub functions are working, and test notifications and unlocks periodically. When local storage fills, review older recordings and confirm the account has no unexpected cloud-related requirements.

Frequently Asked Questions

Do eufy video doorbells require a monthly subscription?

The E340 models in this guide are specified as supporting local storage without a monthly fee. Storage capacity varies by configuration: the standard E340 includes 8GB of built-in eMMC, while bundles with HomeBase 3 or HomeBase S380 support a more expandable local-storage setup. Check the current listing for the exact storage terms and any feature-specific cloud requirements.

What is the difference between dual-camera and single-camera eufy video doorbells?

A dual-camera model uses separate views for people and the floor or package area directly in front of the door. A single-camera model such as the C31 offers a simpler 2K feed with a 4:3 view. Dual cameras are generally more useful for delivery awareness, while single-camera designs may be sufficient for basic visitor communication.

Can I hardwire an eufy E340?

Yes, the listed E340 configurations support both battery and wired operation. Wired mode requires a 16–24V power source, and the quick-release battery must remain installed so it can recharge while the doorbell operates. Turn off power at the circuit breaker and follow the included installation instructions for your model.

Which eufy chime models work with the E340?

The supplied E340 compatibility information includes eufy HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa, and Google Voice Assistant devices. It also allows connection with an existing mechanical chime. The original eufy Wi-Fi Chime T8020 and eufy Chime T8740/T8742 are explicitly not compatible with the listed extra-battery bundle, so verify your model number.

Do all eufy video doorbells support HomeBase?

No. The HomeBase 3 and HomeBase S380 bundles support compatible eufy hubs, but the wired S330 listing states that HomeBase is not supported. The FamiLock S3 Max is also not compatible with HomeBase 2, although it supports HomeBase 3 and Matter. Always check the specific model's compatibility notes before buying a hub or bundle.

Is an eufy video smart lock better than a separate doorbell and lock?

It depends on your door and priorities. The E330 and FamiLock S3 Max combine cameras, remote access, and keyless entry in one device, which can reduce hardware at the door. A conventional E340 or C31 is usually easier to add without replacing an existing deadbolt and may be the better choice for straightforward visitor monitoring.

How much night vision detail can I expect from the E340?

The E340 is specified with color night vision, a dual-light system, advanced light capture and processing, and a clear nighttime viewing distance of up to 16 feet, or 5 meters. Results will depend on porch lighting, weather, camera placement, and reflective surfaces, so a supplemental exterior light can still improve visibility in difficult conditions.

Does the C31 have a package-detection camera?

The C31 uses one 2K FHD camera rather than the E340's two-camera arrangement. It therefore does not provide the same dedicated downward package view. It can still monitor the doorway and communicate with visitors, but buyers who want a floor-level package camera should choose an E340, S330, or camera-equipped smart lock instead.

Final Thoughts on Choosing the Best Eufy Video Doorbell

The eufy E340 HomeBase 3 package is the strongest all-around choice for users who want dual-camera coverage, 2K recording, color night vision, and substantial local storage in one setup. The standard E340 is the best-value starting point, while the E340 Smart Display E10 bundle is the premium choice for households that want automatic indoor alerts and live visitor viewing without using a phone.

Prioritize the needs that cannot be changed after installation. Dual cameras matter for package awareness, wired power suits permanent homes, local hubs help with recording retention, and integrated smart locks suit households seeking keyless access. Check existing chime and hub compatibility carefully, since compatible product families can still contain older models that are excluded from support.

Finally, review the current listing before buying because bundle contents, included accessories, renewed status, and prices can change. The supplied specifications provide a strong basis for narrowing the field, but the live product page is the best source for the latest configuration and compatibility information.
