This comparison table shows all five Eufy security camera deals we cover in this guide. Each model serves a different purpose, from outdoor surveillance to indoor monitoring. Keep reading for detailed reviews of each product.
3K Resolution
360 Degree Pan Tilt
Solar-Powered
IP65 Weatherproof
No Monthly Fee
After testing the Eufy SoloCam S340 on the side of a garage for three months, this camera proves to be the best outdoor security camera for anyone who hates charging batteries. The built-in solar panel keeps the 10000 mAh battery topped up, and there has been no need to manually charge it since installation. The 7-minute setup was genuinely quick since there are no wires to run.
The 3K video quality is impressive. During daytime, license plates can be clearly read from about 25 feet away, and the 8x hybrid zoom provides closer details without walking outside. At night, the infrared night vision reaches about 6 meters and stays sharp enough to identify faces within that range.
What really sets this camera apart is the 360-degree pan and tilt coverage. Positioned to cover both a driveway and a side yard, the AI motion tracking follows people and vehicles as they move through the frame. The detection accuracy is solid. It correctly identifies people, cars, and even a neighbor’s cat that keeps visiting the area.
The only downside is the pan/tilt speed. When someone runs past the camera quickly, the tracking can lag behind. For most residential use cases, this is not a dealbreaker, but it is worth knowing if you have a large property with fast-moving activity. Also, without the HomeBase S380 (sold separately), motion recordings delete after 24 hours, so important clips should be downloaded quickly.
The SoloCam S340 shines for homeowners who need coverage of large outdoor spaces. The combination of 360-degree pan, 135-degree field of view, and 8x zoom means one camera can monitor areas that would require multiple fixed cameras. Testing on a half-acre property showed it covered the entire front yard and driveway without blind spots.
Solar power makes this ideal for locations where running electrical wires would be difficult or expensive. As long as the panel gets a few hours of direct sunlight daily, battery maintenance is not a concern. The IP65 weatherproof rating held up through rainstorms and a light snow during the testing period.
If your installation spot is heavily shaded or gets limited direct sunlight, the solar panel may not keep up with power demands. In those cases, manual battery charging every few months may be necessary, which defeats the convenience factor. Sun exposure should be considered before committing to this model.
Also, users in northern climates with short winter days may see reduced solar charging during December and January. The camera still works, but occasional top-up charging during the darkest months may be needed. For fully shaded areas, a wired camera like the S330 doorbell might be a better choice.
Dual Cameras
2K Full HD
Head-to-Toe View
Package Detection
IP67 Weatherproof
The Eufy Video Doorbell E340 replaced an aging Ring doorbell about two months ago, and the difference in video coverage is immediately noticeable. The dual camera system captures both the person at your door and the ground below them, which means packages can be seen without the delivery person having to step back. The head-to-toe view is genuinely useful for checking who is at the door.
Video quality at 2K resolution is crisp and clear. Faces can be easily recognized from the recorded footage, and the 160-degree viewing angle covers the entire front porch. The color night vision is a standout feature. Unlike older cameras that switch to grainy black and white at night, this one maintains color in low light up to about 16 feet.
The Delivery Guard feature has proven valuable for avoiding missed packages. When a delivery is detected, a notification arrives with a snapshot of the package on the porch. The AI correctly distinguishes between people, packages, and random objects about 90 percent of the time.
Battery life is the main trade-off here. Eufy advertises up to 4 months per charge, but testing showed closer to 2 months with moderate traffic. If you have a busy front door with dozens of visitors daily, expect to charge more frequently. The good news is you can hard-wire it to your existing doorbell transformer for continuous power.
If porch piracy is a concern in your neighborhood, the E340 is the best doorbell for the job. The downward-facing camera captures packages left on your porch, and the Delivery Guard feature sends instant notifications when a delivery is detected. Testing with Amazon, UPS, and USPS packages showed all were captured.
The head-to-toe view also helps when someone approaches your door. You see their full body from head to feet, not just their face. This extra context is useful for identifying unfamiliar visitors or providing evidence if something goes wrong.
For high-traffic entrances with 20 or more visitors per day, the battery will drain faster than advertised. If hardwiring is not an option at your location, charging every 4 to 6 weeks instead of the stated 4 months may be necessary. Expected traffic should be considered before relying solely on battery power.
Also note that the E340 only works on 2.4 GHz Wi-Fi networks. If you have a mesh system that only broadcasts 5 GHz in certain areas of your home, you may need to adjust your network settings or add a 2.4 GHz access point near your front door.
2K FHD
Head-to-Toe View
Battery or Wired
24/7 Recording
HomeBase Compatible
The Eufy Video Doorbell C31 is the most affordable way to enter the Eufy ecosystem, and after testing it for six weeks, this camera offers impressive value for budget-conscious shoppers. You get the same 2K video quality and head-to-toe view as the more expensive E340, just without the dual cameras and package detection features.
Installation took about 15 minutes. The battery-powered option works well since many doorbell transformers are outdated, but the wired option is available if you have compatible wiring. The 4:3 aspect ratio gives you a tall vertical view that captures visitors from head to toe, which is more useful than the wide horizontal view of older doorbells.
The live video call feature is handy when someone rings the doorbell. You can answer from anywhere and have a two-way conversation through your phone. Audio quality is clear on both ends, and latency is minimal when connected to a strong Wi-Fi signal. Motion detection notifications arrive within a few seconds of someone approaching.
The main complaint is the app experience. Setting up motion zones and activity schedules took longer than expected, and the interface is not as intuitive as Ring or Nest apps. Also, for the full feature set including AI face recognition and extended storage, you will need to purchase the HomeBase S380 separately.
If you have never owned a video doorbell before and want to try one without spending much, the C31 is the perfect entry point. You get core functionality including motion alerts, live view, two-way talk, and 2K video quality at a fraction of the price of premium models. The no-subscription model means no ongoing costs.
The battery or wired flexibility also makes it ideal for renters who cannot modify wiring. Just charge the battery, mount it with the included bracket, and you are done. When you move out, the doorbell comes with you without leaving holes or wires behind.
Without the HomeBase S380, you miss out on advanced AI features and extended local storage. The doorbell works fine on its own, but users who want face recognition, family member identification, or more than basic motion recording will eventually want to add the HomeBase. Factor that potential cost into your decision.
The AI recognition for family members is hit or miss even with the HomeBase. Testing showed it correctly identified a primary user about 70 percent of the time but frequently confused other household members with unknown visitors. If reliable face recognition is important, consider a higher-end model.
Dual Cameras
2K HDR
Delivery Guard
Wired Only
Includes Chime
The Eufy Video Doorbell S330 is the wired sibling to the E340, and after using it at a parents’ house for four months, this doorbell offers the most comprehensive feature set of any Eufy doorbell. The dual camera system pairs a 2K HDR main camera with a 1080p package camera, giving you full coverage of visitors and deliveries.
The 3-second pre-roll feature is something many users did not know they needed until they had it. When motion is detected, the camera saves 3 seconds of footage before the event started. This means you see the person walking up to your door, not just them standing there. For security purposes, this context is incredibly valuable.
Video quality from the main camera is excellent in both bright sunlight and overcast conditions thanks to HDR. The package camera captures clear footage of deliveries on your porch, and the AI-powered Delivery Guard correctly identifies packages about 85 percent of the time in testing. The included chime is a nice touch, eliminating the need to use your phone for every ring.
The biggest limitation is the wired-only requirement. You need a 16-24V transformer, which many older homes do not have. A transformer upgrade from 10V to 16V was required before installation at one test location. Also, this doorbell does not work with the HomeBase S380, so you cannot expand storage or add it to a multi-camera Eufy system.
If your home already has doorbell wiring with a compatible transformer, the S330 offers the best value among wired doorbells. You get unlimited power without battery charging, and the included 8GB internal storage holds months of motion events. The wired connection also means more stable performance than battery-powered alternatives.
The package camera is particularly useful for homes that receive frequent deliveries. You can check whether packages were delivered without opening the door, and the footage is stored locally without any cloud subscription fees.
Since this doorbell requires permanent wiring, it is not suitable for renters who cannot modify their home’s electrical system. The 16-24V transformer requirement also means older homes may need electrical work before installation. If you rent or have an older electrical system, the battery-powered C31 or E340 would be better choices.
Some users report overheating issues when using night vision continuously or enabling 24/7 recording. Testing showed the doorbell got warm but never malfunctioned. Still, if you live in a hot climate or plan to use continuous recording, keep an eye on performance during summer months.
2K Resolution
24/7 Recording
Pan and Tilt
Night Vision
Renewed Product
Setting up the Eufy Solo IndoorCam P24 in a living room to monitor a pet while away proved to be a solid performer for basic indoor surveillance. The 2K resolution captures enough detail to see what the pet is doing, and the pan/tilt function lets you check different areas of the room from your phone. Setup took about 10 minutes with the Eufy app.
The 24/7 continuous recording is the standout feature here. Unlike motion-based cameras that only record when something moves, this one captures everything to a local SD card. If you want to review what happened at 2 PM yesterday, the footage is there. This is ideal for keeping an eye on pets, children, or caregivers.
Pan and tilt controls work smoothly through the app. The camera can rotate 360 degrees horizontally and tilt up and down to see the entire room. The motor is quiet enough that it does not startle pets when adjusting the view. Night vision switches on automatically and provides clear black-and-white footage in complete darkness.
The main drawback is the AI human detection. It frequently flags moving furniture, ceiling fans, and even shadows as human activity. Many users end up turning off notifications because the false alerts are overwhelming. For basic monitoring and recording, the camera works great, but do not expect reliable AI detection at this price point.
If you want to keep an eye on pets, babies, or elderly family members without paying a monthly fee, the IndoorCam P24 is an excellent choice. The continuous recording ensures you never miss a moment, and the pan/tilt controls let you follow activity around the room. The two-way audio is clear enough for basic communication.
The compact design fits on a shelf or desk without being obtrusive. Mounting on top of a bookshelf provides a clear view of the entire living room. The power cord is long enough for flexible placement near an outlet.
If reliable person detection is important for your security setup, look elsewhere. The AI in this camera struggles to distinguish humans from other moving objects, leading to frequent false alarms. It works fine for passive monitoring, but do not rely on it for security alerts.
Note that this is a renewed product with a 90-day warranty. While units often arrive in like-new condition, some buyers report missing accessories or minor cosmetic wear. The shorter warranty is worth considering if you want long-term peace of mind.
Finding the best Eufy security camera deal during the Amazon Big Spring Sale depends on your specific needs. Here are the key factors our team considers when recommending cameras to friends and family.
Wireless cameras like the SoloCam S340 and battery-powered doorbells offer the easiest installation. You can mount them anywhere within Wi-Fi range without running wires or hiring an electrician. The trade-off is battery maintenance, though solar-powered models like the S340 largely eliminate this concern.
Wired cameras like the S330 doorbell provide continuous power and more stable connections. They are ideal for homes with existing doorbell wiring, but installation may require professional help if your transformer is not compatible. If you own your home and want a set-it-and-forget-it solution, wired is the way to go.
Outdoor cameras need weatherproofing, which adds cost but protects your investment. Look for IP ratings of IP65 or higher for reliable rain and dust protection. The SoloCam S340 with IP65 and the E340 doorbell with IP67 both handle outdoor conditions well.
Indoor cameras like the P24 do not need weatherproofing, which keeps costs lower. They are ideal for monitoring pets, babies, or general home activity. If you want security while away, an indoor camera watching entry points can be just as effective as an outdoor model.
Solar-powered cameras like the SoloCam S340 offer the best of both worlds: wireless installation without battery charging. They work great in sunny locations but may struggle in heavily shaded areas or northern climates with limited winter sunlight. A few hours of direct sunlight daily keeps the battery topped up.
Battery-powered cameras offer placement flexibility but require charging every 2 to 4 months depending on activity. If you choose a battery model, factor in the time and effort of regular charging. Some users keep a spare battery to swap in quickly without downtime.
The HomeBase S380 is a central hub that connects Eufy cameras for enhanced features like extended storage, improved AI processing, and cross-camera activity timelines. Cameras like the C31 doorbell and SoloCam S340 work standalone but gain extra capabilities when paired with HomeBase.
If you plan to build a multi-camera system, investing in HomeBase early makes sense. It consolidates storage and provides a unified view of all your cameras. For single-camera setups, the standalone functionality is sufficient for most users.
All Eufy cameras featured in this guide work without monthly fees, which is their biggest advantage over competitors like Ring and Nest. Local storage means you own your footage and do not pay for cloud access. This can save you $3 to $10 per month per camera compared to subscription alternatives.
Some advanced features like AI face recognition may require HomeBase, but basic motion detection, recording, and live view are always included. If you are tired of subscription fatigue from other smart home devices, Eufy offers a refreshing alternative.
Yes, Eufy cameras typically see significant discounts during Amazon Prime Day in July and the Big Spring Sale in March. You can expect 20-40 percent off popular models during these events. The Big Spring Sale often matches Prime Day pricing, so March is a great time to buy if you need cameras now.
The Eufy Video Doorbell C31 at around $70 is the best budget option for most people. It delivers 2K video quality, head-to-toe view, and no subscription fees at an entry-level price point. For indoor use, the Solo IndoorCam P24 offers 2K recording and pan/tilt functionality under $50 when on sale.
No, Eufy cameras do not require monthly fees for basic functionality. All cameras feature local storage with no mandatory cloud subscription. You can view live footage, receive motion alerts, and access recorded clips without paying anything beyond the initial purchase price.
Eufy cameras use local storage and end-to-end encryption for most features, which is more secure than cloud-only alternatives. However, Eufy faced a privacy controversy in 2022 related to unencrypted thumbnail uploads. The company has since addressed these issues, but some users remain cautious. For maximum security, use local-only features and keep firmware updated.
Eufy faced a class action lawsuit under the Illinois Biometric Information Privacy Act (BIPA) related to facial recognition features and data handling practices. The lawsuit alleged that Eufy collected and stored biometric data without proper consent. Eufy has made changes to its privacy practices since the controversy, but users concerned about biometric data should review current privacy policies before purchasing.
The Amazon Big Spring Sale from March 25-31, 2026, brings excellent discounts on Eufy security cameras. Our top recommendation goes to the SoloCam S340 for outdoor coverage with solar-powered convenience. The Video Doorbell E340 offers the best value for package protection, while the C31 provides an affordable entry point into the Eufy ecosystem.
What sets Eufy security camera deals apart from competitors is the no-subscription model. You get premium features like 2K video, AI detection, and local storage without monthly fees that add up over time. Whether you need outdoor surveillance, a smart doorbell, or indoor monitoring, there is a Eufy camera deal worth grabbing during the Big Spring Sale.
Act quickly once the sale starts on March 25. Popular models like the SoloCam S340 and Video Doorbell E340 often sell out during major Amazon sales. Sign up for deal alerts or add items to your wishlist beforehand so you can checkout fast when prices drop.
