eufy is best known for home security cameras that save video on hardware you own instead of charging you every month for cloud storage. For a first-time buyer, that one idea is the heart of the brand: you buy the camera once, recordings live on the camera, a microSD card or a small hub called a HomeBase, and the app on your phone shows you what happened. Many eufy outdoor cameras also charge themselves from sunlight, so you never have to climb a ladder to swap batteries.
The six models below range from a tiny single solar camera to a four-camera pan-and-tilt kit and a fully wired eight-camera system, and they differ mainly in picture sharpness, how much ground each camera can turn to watch, and where the footage is stored.

Price and specifications are read from the Amazon product page and can change.
eufy Security SoloCam E42
Best for: Sharpest detail on driveways
Pros
- 4K resolution
- Plates readable to 33 ft
- Siren and strobe light
- Needs 2 hours of sun
Cons
- MicroSD card not included
- 4GHz Wi-Fi only
Best for: Simple solar camera for one entry point
Pros
- Solar keeps it running
- Built-in 8GB storage
- IP67 weather rating
- No monthly fee
Cons
- Black-and-white night vision only
- 4GHz Wi-Fi only
The eufy Security SoloCam S220 is the most straightforward camera in this lineup. It is a small bullet-shaped camera (a bullet camera is the long, tube-like style that points in one fixed direction) that runs on solar power. eufy says about three hours of sunlight is enough to keep it going, and because there are no wires you only need to drill one hole to mount it.
Storage is built right in: the listing names an 8GB eMMC chip, which simply means a small memory chip inside the camera, so you do not need to buy a memory card. Human detection uses on-device AI to tell people apart from moving branches, and if you later add a HomeBase 3 the camera can recognize individual faces. It carries an IP67 rating, which means it is sealed against dust and can survive rain and even brief submersion. Night vision is black and white only, using infrared light, and the camera connects to 2.4GHz Wi-Fi only.
This model suits renters, gift shoppers and anyone who wants to watch one door or gate without learning a whole system. If you need color at night or a camera that can turn to follow someone, the C37 or E42 below are the better fit.
eufy Security eufyCam C37 for Wide Yards
eufy Security
eufy Security eufyCam C37 4-Cam Kit, 360° Pan&Tilt Auto Tracking
Price and specifications are read from the Amazon product page and can change.
eufy Security eufyCam C37 4-Cam Kit
Best for: Covering every side of a house
Pros
- Four pan-and-tilt cameras
- HomeBase Mini included
- Face, pet and vehicle detection
Cons
- Not compatible with HomeKit
- More mounting work
Best for: One camera covering a wide yard
Pros
- 360° pan and tilt tracking
- 2K color night vision
- Detachable 3W solar panel
Cons
- MicroSD card sold separately
- No cloud storage option
The eufy Security eufyCam C37 is a PTZ camera, short for pan, tilt and zoom style movement: the lens can swivel side to side and up and down. eufy describes 360° coverage from one camera, and auto-tracking keeps a person, car or pet centered as they move. It records in 2K, which the listing says delivers 77% more pixels than standard 1080p, and a built-in spotlight lets it show faces and clothing in color after dark.
The solar panel is a separate 3W unit, so you can put the panel in the sun and the camera in the shade if that is where it needs to look. To store video you add a microSD card up to 256GB (sold separately) or connect it to a compatible HomeBase; cloud storage is not supported. The listing lists HomeBase Mini, HomeBase 3, HomeBase Professional, the S4 recorder and the E10 display as compatible, and notes it does not work with HomeKit or HomeBase 2. It connects on 2.4GHz Wi-Fi and is rated IP65, which covers rain and splashing water.
Pick the single C37 if one camera needs to watch a big open space like a backyard. If you want the same camera on several sides of the house, the four-camera kit is the neater buy.
eufy Security SoloCam E42 for 4K Detail
The eufy Security SoloCam E42 is the sharpest wireless camera here, with true 4K recording. eufy says it can make out license plates up to 33 feet away, which makes it a natural choice for a driveway or the street edge of a front yard. Like the C37 it pans and tilts to give 360° coverage and uses AI to detect and follow people and vehicles, which helps cut false alarms.
Two features stand out for a beginner. First, SolarPlus 2.0 charging: eufy says two hours of direct sunlight per day keeps it fully charged, backed by a 44.3 watt-hour battery. Second, a motion-activated siren with a strobe light to startle unwanted visitors. Video goes to a microSD card up to 128GB (not included), or you can pair it with HomeBase S380 for AI features and up to 16TB of storage, or HomeBase S280. It supports 2.4GHz Wi-Fi only.
The E42 suits homeowners who want the most detail from a single wireless camera and a deterrent built in. If you mostly need broad coverage across several sides of the house, a multi-camera kit gives more ground for the effort.
eufy Security eufyCam C37 4-Cam Kit for Whole-Home Coverage
The eufy Security eufyCam C37 4-Cam Kit takes the single C37 camera and multiplies it by four, then adds a HomeBase Mini to tie them together. Each camera keeps the 360° pan and tilt, auto-tracking, 2K color night vision and detachable 3W solar panel described above, plus infrared LEDs alongside the spotlight.
The HomeBase Mini is the key difference. It is a small hub that stays inside your home, holds 64GB of footage built in and can expand to 1TB with a microSD card sold separately. eufy says it links up to 10 cameras in one app and unlocks human, vehicle, pet and facial recognition plus cross-camera tracking, meaning the system can follow someone as they pass from one camera’s view to the next. It is not compatible with HomeBase 2 or HomeKit.
This kit suits a family covering the front, back and both sides of a house who wants everything in one app. It asks for more mounting time than a single camera, and if you only have one area to watch, the single C37 or S220 is plenty.
eufy Security SoloCam S340 for Zoom and Distance
The eufy Security SoloCam S340 in this listing is a four-camera kit (the model name reads S340 4+1). Each camera has two lenses, which the listing calls a dual-camera design, recording in 3K with 8× zoom and clear detail at up to 40 feet. Mounted vertically, it offers 360° pan and tilt so one camera can check a porch, a backyard and a driveway.
Power comes from a removable solar panel, and eufy estimates about seven minutes to install each wire-free camera. The listing promises local storage with no monthly fee but does not specify whether that means a memory card, built-in storage or a hub, so check the product details before you buy if storage matters to you.
The S340 kit suits larger properties where you want to zoom in on something far from the house. If you prefer the simplicity of a kit whose hub and storage are clearly spelled out, the C37 4-Cam Kit is easier to understand.
8× 4K Turret Cameras PoE NVR for a Wired Setup
Best for: Wired, always-recording whole-property system
Pros
- Eight 4K turret cameras
- Continuous recording
- Expands to 16 channels
- IP67 weatherproof
Cons
- Needs Ethernet cabling
- Not wireless
The 8× 4K Turret Cameras PoE NVR system, sold as the E41, is the one product here that is not wireless, and it is included so you can see the alternative. PoE stands for Power over Ethernet: a single network cable carries both power and video to each camera, and an NVR (network video recorder) is the box that stores the footage.
You get eight 4K turret cameras with a 122° field of view, starlight color night vision, IP67 weatherproofing and a local AI agent for real-time detection and smart video search. The recording mode is continuous event, and the system can grow to 16 channels and 16TB of storage. Because it is corded, there are no batteries or solar panels to think about, but you do have to run cables.
This system suits homeowners who are comfortable with a wired installation, or who hire someone for it, and want nonstop recording on many cameras. Anyone who wants a quick, drill-one-hole setup should stay with the wireless models above.
How to Choose the Right eufy Wireless Outdoor Camera
Start with how many areas you need to watch. One door or gate points to the SoloCam S220 or a single C37. Several sides of the house point to the C37 4-Cam Kit or the S340 kit. A large property with many angles and a willingness to run cable points to the E41 PoE system. For more background on the brand, our guide to eufy security cameras for wireless outdoor use walks through the basics.
Next, think about detail. For a driveway where plates matter, the 4K E42 leads the wireless group. The S340’s 8× zoom helps with distant objects, while the C37’s 2K is enough for faces near the house. If color at night matters, note that the S220 records only in black and white after dark.
Then decide on storage. The S220 stores video inside the camera. The C37 and E42 need a microSD card or a HomeBase, and neither card is included. The C37 kit includes a HomeBase Mini, which is the easiest way to get facial recognition and one place for all footage.
Finally, check your Wi-Fi and sun. The S220, C37 and E42 listings all specify 2.4GHz Wi-Fi only, so make sure your router offers that band, which most do. Solar charging needs a spot with a few hours of direct light each day. If you also want cameras inside, our look at wireless indoor cameras covers that side of the home.
FAQ
Do eufy outdoor cameras need a monthly subscription?
No. Every listing here stresses no monthly fee. Video is kept locally on the camera, a microSD card, a HomeBase or an NVR, rather than in paid cloud storage.
Which eufy solar security camera needs the least sunlight?
According to the listings, the SoloCam E42 needs about two hours of direct sunlight a day, while the SoloCam S220 needs about three. The C37 listings describe continuous charging from a 3W panel but do not give a number of hours.
Do I need a HomeBase?
Not always. The S220 has built-in storage and the C37 and E42 can record to a microSD card. A HomeBase adds features such as facial recognition and more storage, and the C37 4-Cam Kit already includes a HomeBase Mini.
Will these cameras work with 5GHz Wi-Fi?
The S220, C37 and E42 listings say they support 2.4GHz Wi-Fi only. The S340 listing does not specify the band, and the E41 system is wired through Ethernet instead of Wi-Fi.
Which eufy wireless outdoor security camera should a beginner buy?
For one spot and the easiest setup, the SoloCam S220 is the simplest. For wide coverage and color night vision from one camera, choose the eufyCam C37. For the most detail, choose the SoloCam E42.
Can these cameras work with Alexa?
The S220, C37, E42 and C37 kit listings name Amazon Alexa as a supported controller. The S340 and E41 listings do not specify.
