1. Eufy Video Doorbell E340 – Best Overall Balance
Eufy Security Video Doorbell E340
Dual camera system
2K Full HD resolution
8GB local storage
Battery or wired
The eufy Security Video Doorbell E340 is the most balanced standalone model in this roundup, earning a 4.0 rating from the supplied data. Its defining strength is the two-camera arrangement: a forward-facing lens records visitors, while a downward-facing lens provides a head-to-toe view of the entrance and the ground where packages are usually left. That combination addresses the most common blind spot in a traditional doorbell camera without requiring a separate security camera.
Pros
- Excellent package visibility
- Flexible installation options
- Built-in local recording
- Useful color night vision
- Broad chime compatibility
Cons
- Basic bundle lacks chime
- HomeBase storage expansion absent

Image quality is specified at 2K Full HD, with a dual-light system and advanced light-processing algorithm supporting color night vision. The listed clear nighttime viewing distance reaches up to 16 feet, or five meters. Local recording is handled through 8GB of built-in eMMC storage, allowing the doorbell to operate without a monthly fee. The device can also work with compatible HomeBase models and chimes, giving buyers options for expanding storage and audible alerts.
Installation flexibility is another major strength. A quick-release rechargeable battery makes battery installation straightforward, while a 16–24V wired connection can keep the battery topped up for longer-term operation. The trade-offs are that this listing focuses on the doorbell itself rather than including a chime or HomeBase, and the built-in storage is smaller than the expandable storage available in the HomeBase bundle. Buyers wanting a one-package setup may prefer a more complete configuration.
This is the strongest general recommendation for someone who wants package awareness, visitor identification, and flexible power without a recurring fee. It suits both renters and homeowners, provided the existing doorbell wiring is compatible. Choose the plain E340 if you already have a suitable chime or plan to use the built-in storage; select a bundled version if you need more capacity or an extra battery from the outset.
A Purpose-Built Package View
The lower camera is the E340's most important differentiator. It fills in the floor-level view that a single high-mounted lens can miss, making it easier to monitor where a courier leaves a parcel.
Storage Without a Subscription
Built-in eMMC storage supports local recording without ongoing cloud fees. Compatible HomeBase and chime options provide additional flexibility, although they are not required for the core experience.

2. Eufy E340 with HomeBase 3 – Best Local Storage
Eufy Video Doorbell E340 with HomeBase 3
Dual camera system
2K Full HD resolution
16GB built-in storage
Expandable to 16TB
This E340 and HomeBase 3 package earns a 4.6 rating and stands out as the most storage-focused recommendation. The E340 retains the dual-camera design, 2K Full HD resolution, flexible battery or wired operation, and color night vision. Adding HomeBase 3 changes the proposition by introducing 16GB of built-in storage at the base and expansion of local recordings up to 16TB.
Pros
- Large expandable storage
- Advanced BionicMind features
- Excellent dual coverage
- Flexible power operation
- No recurring storage fees
Cons
- More complex initial setup
- Bulkier overall configuration
We may earn a commission when you buy through this link, at no additional cost to you.
That capacity is particularly useful for households that want long recording windows and do not want to pay a monthly fee for video access. The supplied information also identifies BionicMind features, including facial recognition that filters alerts, self-learning AI described as improving accuracy to 99.9%, and automatically categorized security reports. Push-notification thumbnail previews may temporarily use cloud image storage, a nuance worth considering for privacy-conscious buyers.
The main compromise is complexity. A standalone E340 can be installed and used with little additional equipment, while this bundle requires setup of both the doorbell and base. The benefits are substantial for someone building a broader local-security system, but they may be unnecessary if 8GB of doorbell storage is enough. Compatibility with existing mechanical chimes and supported eufy accessories also makes it more adaptable than a tightly isolated single-device setup.
Choose this bundle when local retention, expandable capacity, and centralized eufy functionality matter most. It is a particularly strong option for users who want the E340's package-focused dual view but expect to add more cameras or other compatible devices later. If you only need a simple visitor alert and a small amount of local recording, the less elaborate E340 configuration may be more appropriate.
Expandable Local Recording
HomeBase 3 supports storage expansion to 16TB, giving users a way to preserve more footage without depending on a recurring subscription. Built-in storage also provides a useful starting point.
Smarter Alert Filtering
BionicMind is intended to reduce unnecessary notifications and organize security events. Facial recognition and self-learning features make the base more valuable for users building a broader ecosystem.

3. Eufy E340 with Backup Battery – Best Battery Convenience
Eufy E340 with Backup Battery
Dual camera system
2K Full HD resolution
Extra 6,500mAh battery
Compatible chime included
The E340 with an extra quick-release rechargeable battery and chime earns a 4.6 rating, making it a strong choice for households that prioritize simple maintenance. The included second battery has a listed capacity of 6,500mAh, allowing one pack to remain installed while the other is charged or swapped. That arrangement can reduce the inconvenience of taking the doorbell offline whenever its primary battery needs attention.
Pros
- Two-battery system included
- Quick-release battery design
- Compatible chime included
- Strong nighttime clarity
- Local storage without fees
Cons
- Incompatible with older chimes
- Backup battery adds bulk
We may earn a commission when you buy through this link, at no additional cost to you.
Core imaging is identical in spirit to the other E340 configurations. Two cameras cover people and the floor in front of the entrance, 2K Full HD resolution preserves useful detail, and the dual-light system supports color night vision with a stated viewing distance of up to 16 feet. Local storage is available without subscription fees, while a compatible chime provides audible alerts inside the home.
Compatibility deserves careful attention. The doorbell can connect with the HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. It is specifically not compatible with the original eufy Wi-Fi Chime T8020 or eufy Chime T8740 and T8742. If you own one of those excluded accessories, verify the model number before purchasing. Keeping a spare battery also means maintaining a second pack over time.
This bundle is ideal for a home without straightforward doorbell wiring, especially when household members want an audible indoor alert. It is also more complete than the standard E340 because both a spare battery and a compatible chime are included. Buyers who already have a supported eufy base or chime can save money by choosing a simpler configuration, but the supplied feature set makes this option particularly approachable for first-time owners.
Swap Batteries Without Waiting
The quick-release design makes each 6,500mAh pack easy to remove. Keeping two packs ready reduces charging gaps and simplifies routine front-door maintenance.
A Complete Battery-First Setup
A compatible chime is included, so the bundle supports both mobile and in-home alerts. Check your existing chime model because several older eufy units are excluded.

4. Renewed Eufy E340 – Best Value With Dual View
Eufy E340 Renewed
Dual camera system
2K Full HD resolution
Color night vision
Renewed condition
The renewed eufy Security Video Doorbell E340 carries a 4.4 rating and gives buyers access to the model's dual-camera design at a potentially different value tier from new inventory. The forward camera focuses on visitors, while the downward camera fills in the view of the floor and doorstep area. That is particularly useful for anyone who regularly receives packages or wants to monitor porch activity more completely.
Pros
- Core E340 dual coverage
- Battery or wired flexibility
- HomeBase S380 compatible
- No recurring subscription
- Delivery Guard included
Cons
- Renewed cosmetic condition varies
- Older accessories remain incompatible
We may earn a commission when you buy through this link, at no additional cost to you.
The specified imaging features include 2K Full HD resolution and color night vision reaching up to 16 feet. Battery operation simplifies installation, while a 16–24V wired source with the battery installed can top it up continuously. The renewed listing also supports local storage without subscription fees and compatibility with HomeBase S380, the HomeBase S280, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices.
The defining trade-off is condition. Renewed products may show cosmetic wear, and the supplied data does not state the original packaging or accessory completeness. As with the standard E340, the original Wi-Fi Chime T8020 and Chime T8740 or T8742 are not supported. Buyers should review the listing carefully and confirm the included components rather than assuming they match a new retail package.
This is a sensible option for a practical shopper who values the E340's core features and accepts refurbished cosmetic wear. It is particularly compelling for anyone who wants Delivery Guard, flexible power, and local recording without paying for a premium bundle. Choose it over a new unit if the savings are meaningful and you are comfortable assessing the condition offered.
Dual Coverage at a Lower Tier
Renewed inventory retains the E340's visitor-and-floor camera arrangement. It remains focused on the same practical package monitoring that distinguishes the model from a single-camera doorbell.
Understand Renewed Condition
Refurbished status can introduce visible marks or differences in packaging. Confirm the doorbell, battery, mounting hardware, and any stated accessories before completing the purchase.

5. Eufy Video Doorbell C31 – Best Straightforward Doorbell
Eufy Security Video Doorbell C31
Single 2K camera
Four-by-three field view
6,500mAh quick-release battery
Battery or hardwired
The eufy Security Video Doorbell C31 has a 3.9 rating and offers a more traditional single-camera approach than the E340. Its 2K FHD sensor uses a four-by-three field of view, producing a wider, more vertically oriented image than many standard doorbell formats. That aspect ratio can help retain both a visitor's face and more of the area directly in front of the door.
Pros
- Simple 2K imaging
- Flexible power installation
- Quick visitor responses
- Supports continuous recording
- No recurring subscription
Cons
- No downward package camera
- SD card not included
We may earn a commission when you buy through this link, at no additional cost to you.
Communication features center on a pop-up video call when the bell is pressed. Users away from home can rely on quick responses, and the specification says visitors can leave voice messages. A 6,500mAh quick-release rechargeable battery supports simple installation, while hardwiring is available for users who want constant power and uninterrupted operation.
Hardwired mode adds meaningful functionality: continuous 24/7 recording and five-second pre-roll for motion-activated events. Installation requires bypassing the existing chime, and an SD card for removable storage is not included. The single lens also cannot provide the dedicated downward view offered by the E340, so package monitoring depends entirely on how much floor area falls within the four-by-three frame.
The C31 is the most approachable choice for someone who wants a clear doorbell without dual-camera complexity or a complete ecosystem bundle. It is a good fit for apartments, straightforward installations, and users who prioritize a simple video call and flexible recording modes. Buyers whose main concern is checking the exact location of every package should favor the E340 instead.
A Wider Vertical Perspective
The four-by-three format is intended to balance headroom and floor coverage. It is still a single-camera view, but it can show more of the entrance than a narrow, traditional aspect ratio.
Recording That Suits Different Needs
Battery mode prioritizes simple installation, while hardwiring enables continuous recording and five-second pre-roll. Existing chime bypass and the lack of an included SD card should be considered before installation.

6. Eufy Video Smart Lock E330 – Best Keyless Entry Upgrade
Eufy Video Smart Lock E330
2K HD camera
Fingerprint keyless entry
10,000mAh rechargeable battery
IP65 weather resistance
The eufy Security Video Smart Lock E330 earns a 4.1 rating and belongs in this guide as an adjacent alternative for shoppers who want a video doorbell and smart lock in one device. It combines a 2K HD camera with an f/1.6 lens, fast fingerprint recognition, keypad access, physical keys, and control through the eufy Security app, Alexa, or Google Voice Assistant.
Pros
- Combines lock and camera
- Fast fingerprint access
- Multiple entry methods
- Relatively quick installation
- BHMA Grade 3 certified
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.
Its camera is intended to provide front-door awareness even after dark, while the lock gives family members, guests, and everyday visitors several ways to enter. The app offers remote access management and real-time notifications for visitors and entry activity. Thumbnail preview images included in push notifications are temporarily stored in the cloud, which is a relevant consideration for users focused on local-only operation.
A 10,000mAh rechargeable battery powers the lock and video functions. Installation is stated to take about 15 minutes without drilling on most standard US deadbolt setups, and the product carries BHMA Grade 3 certification plus IP65 weather resistance. The trade-off is that this is fundamentally a smart lock rather than a conventional doorbell, and compatible eufy Chime, HomeBase 3, cameras, and doorbells are sold separately.
Choose the E330 when keyless entry is central to your front door and consolidating access control with video awareness appeals to you. It is less suitable for someone who only wants a simple chime button, or for a home whose door and deadbolt configuration is outside the stated standard setup. Confirm measurements, strike placement, and accessory needs before installation.
Entry and Monitoring Combined
Fingerprint access removes the need to search for a key, while keypad, app, voice-assistant, and physical-key options provide alternatives for different household members and guests.
Designed for Everyday Installation
The stated no-drill process works on most standard US deadbolt setups and can simplify the transition to an integrated smart lock. Weather resistance and Grade 3 certification support regular exterior use.

7. Eufy S330 with Chime – Best Wired Package Monitor
Eufy Video Doorbell S330 with Chime
Dual camera system
2K HDR imaging
Three-second pre-roll
Wired 16–24V operation
The eufy Security Video Doorbell S330 with Chime has a 4.0 rating and is a practical wired choice for homes with compatible doorbell power. Dual cameras improve front-door coverage, while 2K HDR video is designed to retain more detail in bright and dark areas. Delivery Guard is the standout feature, detecting packages and sending arrival, pickup, and tampering alerts.
Pros
- Strong package detection
- Useful activity pre-roll
- Indoor chime included
- HDR image detail
- No monthly subscription
Cons
- HomeBase not supported
- Wired installation required
We may earn a commission when you buy through this link, at no additional cost to you.
A three-second pre-roll provides context before a motion event, helping users understand what prompted a notification instead of seeing only the moment detection begins. The included chime supports indoor awareness, and the product works with Alexa and Google Assistant for voice control and smart-home integration. Local operation does not require a monthly subscription.
The constraints are significant. This S330 configuration is wired and requires compatible 16–24V, 30VA power, making it less convenient for a quick retrofit in a home without existing wiring. HomeBase is expressly unsupported, so it is not suitable for buyers hoping to create a broader local eufy storage network. Alerts are also described as motion-only, which may make the device less useful for people who want every ring or door event sent directly to the phone.
This doorbell is best for a wired home where package management is a priority and a supported indoor chime is welcome. It is particularly attractive for users who want Delivery Guard, pre-roll context, and 2K HDR without a recurring fee but do not need HomeBase expansion. Verify your transformer rating and existing wiring before ordering.
Package Alerts With Context
Delivery Guard watches for parcels and can provide arrival, pickup, and tampering notifications. The three-second pre-roll adds useful context to motion-triggered activity.
A Purpose-Built Wired System
The S330 emphasizes stable wired operation and indoor chime alerts. Its lack of HomeBase support means it should be evaluated as a self-contained option rather than the foundation of an expandable eufy hub.

8. Eufy FamiLock S3 Max – Best Palm Vein Access
Eufy FamiLock S3 Max
2K HD camera
Palm vein recognition
150-degree viewing angle
Rear lock video display
The eufy Security Video Smart Lock FamiLock S3 Max has a 4.2 rating and is built around distinctive palm vein access. Its biometric system recognizes a user's vein pattern in 0.6 seconds, and the supplied information states that the data remains stored locally on the lock. That focus on local biometric storage may appeal to households that want fast entry without relying on a physical key.
Pros
- Fast palm vein recognition
- Local biometric storage
- App-free rear display
- Wide entry-area view
- Broad Matter support
Cons
- Camera streams unsupported via Matter
- Not compatible with HomeBase 2
We may earn a commission when you buy through this link, at no additional cost to you.
The device combines a 2K HD camera with an f/1.8 lens, a 150-degree head-to-toe view, and real-time visitor alerts. A rear lock video screen provides a simple way to check front-door status without opening a smartphone app, which could be useful for children and older adults. This makes the product more than a traditional lock or doorbell.
Power is handled by a rechargeable battery rated for up to four months of full functionality, with four AAA batteries providing another month of essential operation during an outage. Matter support extends connectivity to Apple Home, Google Home, Alexa, and SmartThings, but camera streams are not supported through Matter because of current limitations. It is also not compatible with HomeBase 2.
The S3 Max is best for buyers seeking a combined access-control, camera, and video-entry solution rather than a conventional doorbell. The rear screen and palm recognition are particularly useful for multi-generational households. For a standard doorbell use case, however, an E340-style model offers a more direct path to package monitoring and visitor alerts.
A Different Kind of Biometric Access
Palm vein recognition uses unique internal vein patterns and is specified to unlock in 0.6 seconds. Storing the recognition data locally gives the lock a more privacy-conscious design foundation.
Visible Status Without an App
The rear video screen lets household members inspect the front entrance directly. That simple interface can be especially helpful for children and older residents who may not want to manage a mobile application.

9. Eufy E340 Complete Bundle – Best Ready-Made System
Eufy E340 Complete Bundle
Dual camera system
2K Full HD resolution
HomeBase S380 included
Extra 6,500mAh battery
This complete E340 bundle earns a 4.5 rating and combines three useful components: the E340 doorbell, an extra 6,500mAh quick-release rechargeable battery, and HomeBase S380. The doorbell delivers the familiar dual-camera view, 2K Full HD resolution, and color night vision with a stated range of up to 16 feet.
Pros
- Doorbell and base included
- Two rechargeable batteries
- Expandable local ecosystem
- Excellent package visibility
- No monthly subscription
Cons
- Largest bundle footprint
- Older chime models unsupported
We may earn a commission when you buy through this link, at no additional cost to you.
The backup battery reduces the inconvenience of charging interruptions, while HomeBase S380 provides a central foundation for compatible eufy devices and local storage. Recordings can remain local without a subscription, making the package attractive to households that want dependable monitoring without a recurring storage plan. It is a more complete answer than buying only the camera and discovering later that a base or spare battery is needed.
The main drawback is that a complete package may be more than a single-doorbell household requires. It also occupies more setup time and shelf space than the standard E340, and the battery is not compatible with the original Wi-Fi Chime T8020 or the T8740 and T8742 chimes. Existing mechanical chimes and other compatible eufy accessories can be used according to the supplied guidance.
Choose this configuration if you want a ready-made eufy front-door system with backup power and a local hub. It is a strong choice for new smart-home users, frequent package recipients, and anyone expecting to add compatible equipment later. If your priorities are limited to one camera and one alert method, a less comprehensive E340 bundle may be easier to manage.
Everything Needed for Continuity
Two rechargeable battery packs support quick replacement, and the included base provides local ecosystem storage. The arrangement reduces the need to purchase several accessories separately.
A Foundation for Expansion
HomeBase S380 is the centerpiece for a broader eufy setup. It is particularly useful for users who want local recording and may later add compatible cameras or other home-security devices.

10. Eufy E340 with Display E10 – Best Hands-Free Alerts
Eufy E340 with Smart Display E10
Dual camera system
2K Full HD resolution
Color night vision
Smart Display E10 included
The eufy Security Video Doorbell E340 with Smart Display E10 has the highest supplied rating at 5.0 and is the most distinctive package in the roundup. Its defining addition is the E10 display, which automatically shows a live feed and provides a voice alert when someone rings the bell, unlocks the door, or is detected by the camera.
Pros
- Immediate live-display alerts
- Hands-free voice announcements
- Dual package coverage
- Battery or wired flexibility
- No recurring subscription
Cons
- Display needs nearby placement
- Battery mode requires charging
We may earn a commission when you buy through this link, at no additional cost to you.
That creates a useful alternative to constantly checking a phone. Household members can receive immediate, hands-free awareness from an interior screen, while the E340 itself continues to provide dual-camera monitoring, 2K Full HD imagery, Delivery Guard, and color night vision up to 16 feet. The doorbell can operate on its rechargeable battery or be wired with the battery kept topped up.
The premium experience depends on placing the display where it is useful and visible. This makes setup more involved than a doorbell-only purchase, and households without a suitable interior location may receive less benefit from the screen. Battery operation also retains the normal charging and swapping considerations, although the quick-release design helps make that process easier.
This is the best configuration for users who want more than phone-based alerts. It is particularly suitable for busy homes, deliveries, or anyone who appreciates an always-available indoor view of the front door. If you do not need the display, a standard E340 package offers the same core camera benefits with fewer components and a simpler setup.
Alerts That Reach the Room
The E10 responds automatically to a ring, unlock, or camera detection by lighting up with a live feed and voice alert. This reduces the need to retrieve and unlock a phone.
Premium Visibility Around the Clock
Dual cameras, 2K Full HD resolution, Delivery Guard, and color night vision form the core monitoring system. The display makes those feeds more accessible throughout the home.

Buying Guide – How to Choose the Best Eufy Video Doorbell
The right Eufy video doorbell depends on how you monitor deliveries, what your wiring allows, where recordings are stored, and how much you value a separate indoor display. Use the following factors to narrow the field before choosing a configuration.
Single or Dual Camera Coverage
A single camera is simpler and may be enough when your main goal is answering visitors from a conventional front door. The C31 uses one 2K FHD camera with a four-by-three field of view, balancing vertical coverage and a wide view of the entrance. A dual-camera system adds a dedicated lower perspective. On the E340 and S330, the front lens focuses on people while the downward lens captures the floor, providing a clearer view of packages and porch activity.
Choose dual cameras when package awareness matters or when blind spots below a high-mounted camera are a concern. Choose a single camera when simplicity, a more compact design, and a lower-complexity setup are your priorities.
Resolution and Night Visibility
All of the conventional doorbells in this guide offer 2K-class imagery, but resolution alone does not determine low-light usefulness. The E340 and S330 feature dual-light systems and color night vision, with a listed clear viewing distance of up to 16 feet, or five meters. The C31 specifies crisp night imagery without the same advanced dual-light description. Consider not only the sensor resolution but also the doorbell's illumination system, placement, and proximity to the area you want to inspect.
Prioritize color night vision and a useful stated viewing range when nighttime delivery monitoring matters. Ensure the camera angle covers the critical zone rather than relying on resolution to compensate for poor positioning.
Battery, Wired, or Both
Battery power makes installation simpler and is appropriate for homes without usable existing wiring. Quick-release batteries can be removed and charged away from the door. Wired operation removes battery charging as a routine task and can enable features such as continuous 24/7 recording and five-second pre-roll, as specified for the C31. Several E340 configurations can also use a 16–24V source while retaining the battery as a backup.
Choose battery operation for retrofit convenience, quick swaps, and fewer electrical requirements. Choose hardwiring for constant availability and uninterrupted recording. For hardwired models, verify the required voltage, transformer output, chime-bypass procedure, and whether the battery must remain installed.
Local Storage and Subscription Needs
Several options emphasize local recording without a monthly fee. The standard E340 includes 8GB of built-in eMMC storage, while the HomeBase 3 package includes 16GB and can expand local storage up to 16TB. The C31 supports an SD card, although one is not included. The S330 bundle explicitly does not support HomeBase, making storage expansion a more limited consideration.
Prioritize local storage if avoiding recurring fees and retaining control of recordings are important. Check capacity, expansion limits, and included media before buying. Also note that push-notification thumbnail previews can involve temporary cloud image storage even in systems that otherwise support local recording.
Indoor Alerts and Smart-Home Compatibility
A phone can provide the most important alerts, but an indoor chime makes visitor activity easier to notice. E340 configurations can pair with compatible eufy chimes, HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. The C31 supports HomeBase S380, MiniBase Chime, Alexa, and Google Voice Assistant. Some older eufy chimes are explicitly excluded from E340 compatibility.
Check the exact model number of every accessory you already own. Also distinguish basic voice-assistant compatibility from advanced local features, since some hub-dependent functions may not be available through a third-party voice platform.
Package Monitoring Features
Delivery Guard is a major advantage for people who frequently receive parcels. The S330 and the E340 Smart Display package explicitly list it, while the E340's lower camera provides the visual foundation for package awareness. Delivery-oriented functions can include package detection, arrival notifications, pickup reminders, and tampering alerts depending on the exact model and bundle.
Prioritize a downward camera for visual confirmation and Delivery Guard for automated package notifications. Consider how your alerts are delivered: mobile-only alerts may go unnoticed, while an indoor chime or smart display provides a more immediate signal.
Display and Keyless-Entry Alternatives
The E340 with Smart Display E10 adds an interior screen that shows a live feed and provides voice alerts when a ring, unlock, or camera detection occurs. It is ideal if you want a permanent, glanceable way to know who is outside. The Video Smart Lock E330 and FamiLock S3 Max go further by combining video with keyless entry, fingerprint or palm vein recognition, and multiple access methods.
Choose the E10 bundle for an added display without replacing your lock. Choose a video smart lock when removing physical keys is a primary goal, but verify door compatibility, installation requirements, and included accessories before making the switch.
New, Renewed, and Complete Bundles
A standard E340 offers the core hardware, while bundles add a chime, an extra 6,500mAh battery, HomeBase 3, HomeBase S380, or the E10 display. The renewed E340 can provide the same central camera features in refurbished condition, though cosmetic wear and package contents may vary. A complete bundle is convenient when you want fewer separate purchases; a doorbell-only option is usually simpler.
Match the bundle to your actual needs rather than assuming more accessories always mean more value. List the chimes, bases, batteries, and displays you already own, then check compatibility. If renewing is acceptable, review the condition details and included components carefully.
How to Use and Care for Your Eufy Video Doorbell
Begin by identifying whether your doorbell will run on battery or existing wiring, then confirm that the transformer meets the model's voltage and power requirements. For hardwired installations, turn off power at the circuit breaker before connecting cables, and follow the stated chime-bypass procedure. Battery-powered units are easier to retrofit, but you should test the removable pack and understand the expected charging and swapping routine before mounting the camera.
Mount the doorbell at a height that provides a useful view of visitors and the relevant floor area. After installation, use the eufy Security app to complete setup, adjust motion sensitivity, connect the chime or HomeBase, and test the live feed. If using Delivery Guard, walk a test parcel through its detection area, verify arrival and pickup notifications, and adjust the camera angle if the package is not centered. For smart displays and locks, test every access method and every household notification channel.
Care for the system by keeping the lens clean, checking the rechargeable battery before performance declines, and confirming that storage remains available. Review local storage capacity, compatible accessory connections, and notification settings periodically. For renewed or battery-heavy configurations, inspect the battery contacts and charging pack more often. Follow the manufacturer's safety instructions when replacing a battery, inserting storage, or working with low-voltage doorbell wiring.
Frequently Asked Questions
Which Eufy video doorbell has the best package coverage?
The E340 models offer the most clearly defined package advantage because their downward-facing camera captures the floor directly in front of the entrance. The S330 also pairs dual cameras with Delivery Guard, including package arrival, pickup, and tampering notifications. Your choice should depend on whether you value a complete local hub, a spare battery, an indoor display, or simply a more straightforward wired system.
Do Eufy video doorbells require a monthly subscription?
The featured models emphasize local storage and no recurring subscription for core recording functions. Some E340 bundles include expandable local storage through a HomeBase, while the C31 can use an SD card, although one is not included. Push-notification thumbnail previews may temporarily use cloud image storage even when the main recording system is local, so privacy-conscious buyers should review the current app disclosures.
Can I hardwire an E340 video doorbell?
Yes, the E340 supports both battery and wired operation. In wired mode, the listed requirement is a 16–24V power source, and the rechargeable battery remains installed while the wired supply tops it up. Confirm the transformer's output and follow all breaker and low-voltage safety instructions before installation.
Are older eufy chimes compatible with the E340?
The original eufy Wi-Fi Chime T8020 and eufy Chime T8740 or T8742 are not compatible with the E340 according to the supplied product information. Supported devices include compatible existing mechanical chimes, HomeBase S280, HomeBase S380, MiniBase Chime T8023, Alexa devices, and Google Voice Assistant devices. Check the model number on your current chime before purchasing.
What is the difference between the E340 and C31?
The E340 uses two cameras, combining a visitor-focused view with a downward package view. It also offers advanced color night vision and multiple bundle options involving chimes, batteries, HomeBase models, or the E10 display. The C31 uses one 2K camera with a four-by-three view, offers a simpler traditional format, and supports battery or hardwired operation with continuous recording in wired mode.
Should I choose a video doorbell or a video smart lock?
Choose a video smart lock when keyless entry is the priority. The E330 supports fingerprint recognition, while the FamiLock S3 Max uses palm vein recognition and adds a rear video screen. Choose an E340-style doorbell when you want easier installation, a dedicated package view, and the option to retain your existing lock.
Is a HomeBase necessary for an E340?
No, the standard E340 includes built-in local storage and can operate without a HomeBase. A compatible base can be useful for expanded storage, broader smart-home integration, and additional eufy devices. The HomeBase 3 bundle supports storage expansion up to 16TB, while the S330 configuration in this guide explicitly does not support HomeBase.
How should I position an Eufy video doorbell?
Mount it high enough to see a visitor clearly but low enough for the downward camera to capture where parcels are placed. Check the live feed in both daylight and darkness, then adjust the angle rather than relying on digital zoom. Test package notifications and motion activity after installation, and keep the lens clean for reliable identification.
Final Thoughts on Choosing the Best Eufy Video Doorbell
The eufy Security Video Doorbell E340 is the strongest all-around recommendation because it combines a visitor camera, a dedicated package view, 2K Full HD imaging, color night vision, local storage, and flexible power. The HomeBase 3 version is ideal for expanded local storage, the backup-battery bundle is convenient for simple maintenance, and the Smart Display E10 configuration is the best choice for hands-free indoor alerts.
For a simpler and more traditional experience, the C31 provides 2K imagery, a four-by-three view, and battery or wired operation without the E340's second camera. The wired S330 is a strong package-monitoring system for compatible homes, while the E330 and FamiLock S3 Max make more sense when keyless entry is central to the purchase. Prioritize the camera angle, power method, storage arrangement, and chime compatibility that match your actual home.
Product configurations, bundles, compatibility details, and prices can change over time. Before ordering, confirm the exact model, included accessories, transformer requirements, storage method, and supported chimes on the current listing. This review is based on the supplied product information rather than personal testing, and the final choice should reflect your priorities for package monitoring, privacy, installation, and smart-home integration.
