Key takeaways
- Ten Eufy Security camera listings compared by title specs, from solar eufyCam and SoloCam kits to the plug-in C31 and the S4 Max system, with picks by power source.
Which Eufy camera is best depends mostly on how many spots you need to watch and whether you have a power outlet nearby. For yards with no outlets, the solar kits in this list (eufyCam C37, SoloCam E42, S340 and E30) lean on built-in panels and local storage, while the C31 suits any wall with a plug. Eufy lists many overlapping models on Amazon, and several titles below describe kits while others describe a single camera. We compared ten listings using their own titles, so confirm the pack contents on each page before ordering.

The ten Eufy cameras, one by one
eufyCam C37 4-Cam Kit
This kit’s title packs in four wireless outdoor cameras, 2K resolution, solar power, 360-degree pan and tilt with auto tracking, human, vehicle, pet and face detection, no subscription, and 64GB of built-in local storage. That is a lot of reach for a front door, side gate, garage and back yard in one order. The title does not say how the 64GB is shared, so check the listing.
- Pros: Four solar cameras in one purchase, which avoids running cable
- Pros: Pan and tilt lets each unit sweep a wide area
- Cons: Solar charging depends on sun exposure, so shaded walls need a check
- Cons: Storage split across four cameras is not explained in the title
Who it’s for: Homeowners who want a full perimeter without wiring.
SoloCam E42 4-Cam Kit
The E42 is listed at 4K with solar power, AI facial recognition and motion tracking, a strobe light, pan and tilt, and local storage described as up to 16TB. Four cameras at 4K make it the highest-resolution outdoor kit here on paper. The 16TB figure is a ceiling, so check what storage is actually included.
- Pros: 4K resolution suits reading plates or faces at distance
- Pros: Strobe light adds a visible deterrent
- Cons: Likely the pricier end of the solar kits
- Cons: Included storage versus the 16TB ceiling needs confirming
Who it’s for: Buyers who value image detail over saving money.
eufyCam C35 4-Cam Kit
The C35 is listed as a wireless indoor/outdoor camera with a magnetic mount, color night vision, local storage, no monthly fee, IP67 weather rating and facial recognition. The catch is the phrase solar panel compatible: the panel is not clearly part of the bundle, so budget for it separately if you want solar.
- Pros: Magnetic mount makes repositioning simple
- Pros: IP67 is a higher dust and water rating than the IP66 on the C31
- Cons: Solar panel appears to be an extra purchase
- Cons: Title does not give resolution, so check the listing
Who it’s for: Renters or tinkerers who like moving cameras around.
SoloCam S340 4-Cam Kit
This bundle includes the HomeBase S380 and lists 3K dual-lens solar cameras with 360-degree views, pan and tilt, AI tracking and expandable local storage up to 16TB. Dual lenses are meant to reduce blind spots during a pan. It is the priciest kit here apart from the S4 Max, and the base station adds one more device to power.
- Pros: Dual lenses plus pan and tilt aim to remove blind spots
- Pros: HomeBase keeps footage in one place
- Cons: Base station needs its own outlet and a network connection
- Cons: Costly compared with the 2K kits
Who it’s for: Larger properties that justify a central hub.
eufyCam C37 (solar, single listing)
This C37 listing shares its family name with the 4-cam kit above, but the title gives no pack size. Treat it as an add-on candidate and confirm whether you are getting one camera or a bundle. It lists 2K, a flexible solar panel, 360-degree pan and tilt, human, pet and vehicle detection, and color night vision with no monthly fee.
- Pros: Flexible solar panel is part of the title
- Pros: Probably the lowest-cost way into the C37 line if it is a single unit
- Cons: Unclear pack size makes comparison hard
- Cons: Storage is not mentioned in the title
Who it’s for: People adding one camera to an existing setup.
SoloCam S340 (single camera)
The one-camera version of the S340: 3K dual-lens, solar, 360-degree views, pan and tilt, AI detection, color night vision, no monthly fee and 8GB of built-in storage. Eight gigabytes fills quickly at high resolution, so older footage will be overwritten, and the title does not mention a base station.
- Pros: Lets you try the S340 line without buying four
- Pros: Dual-lens design with 360-degree views
- Cons: 8GB built-in storage is small for 3K video
- Cons: Expandability is not stated in the title
Who it’s for: One-spot buyers with a sunny mounting location.
SoloCam E30 4-Cam Kit
A step below the E42, the E30 kit lists 2K solar cameras with 360-degree views, pan and tilt, AI tracking, no monthly fee and built-in local storage up to 16TB. It overlaps heavily with the C37 kit, so decide on storage wording and the camera family you prefer rather than a big spec gap.
- Pros: Four cameras with the same pan-and-tilt feature set
- Pros: Local storage rather than a subscription
- Cons: Similar to the C37 kit, which makes choosing tricky
- Cons: The 16TB figure needs the listing’s fine print
Who it’s for: Middle-budget shoppers who want a multi-camera solar kit.
4K Indoor Camera E30 2-Pack
This is not an outdoor camera. It is a two-pack of 4K indoor units with pan and tilt, AI tracking, color night vision, two-way audio, human and pet detection and HomeKit support, listed for pet, baby or nanny use. Include it only if you also need monitoring inside.
- Pros: HomeKit support helps Apple households
- Pros: Two units cover two rooms in one order
- Cons: Indoor only, so it will not replace the outdoor models
- Cons: Plug-in power limits placement
Who it’s for: Pet owners and parents who want indoor monitoring.
Camera System S4 Max
Listed as a 4-camera, 2TB system with 4K triple-lens bullet-PTZ hybrid cameras, cross-camera tracking, 24/7 recording, smart video search, 8x auto zoom, starlight color night vision, up to 16 channels and no subscription. It is the largest system on this page, so expect a more involved installation than the solar kits.
- Pros: Cross-camera tracking follows a person between views
- Pros: 24/7 recording with 2TB of storage
- Cons: Highest cost on the list by a wide margin
- Cons: Installation is likely more demanding than the wireless kits
Who it’s for: Owners of large properties who want a recorder-style setup.
Indoor/Outdoor Camera C31
The simplest listing here: a plug-in powered camera with spotlight-free PURECOLOR VISION, IP66, AI detection for humans, vehicles, pets and crying, 24/7 recording and no subscription. Because it is plug-in, it suits porches, garages and sheds with an outlet rather than open yards.
- Pros: No battery or solar to manage
- Pros: 24/7 recording supported in the title
- Cons: Needs a power outlet within reach of the cable
- Cons: Single camera only, with no pan and tilt listed
Who it’s for: Anyone wanting a low-effort camera on a powered wall.
How we picked these
We selected ten Eufy Security listings from Amazon and compared them using their titles, published specifications, manufacturer documentation and buyer reviews. Models were grouped by power source and system type, and we flagged anything the title leaves unclear, such as pack size. Nobody on the team used or measured these units. Check each product page for current contents, compatibility and base station requirements before you buy.
What to look for in a Eufy camera
Power: solar, plug-in or system
Solar kits trade wiring for dependence on daylight. A wall that gets only a couple of hours of direct sun can leave a battery camera underfed, so look at where light actually falls before choosing. Plug-in models like the C31 avoid that problem but need an outlet and a cable route. System packages such as the S4 Max add a recorder and more installation work in exchange for continuous recording.
Storage and the subscription question
Every Eufy listing here says no subscription or no monthly fee, which usually means footage stays on local storage. That only helps if the capacity is large enough. A single 8GB camera overwrites quickly at high resolution, while 2TB across four cameras holds far more history. A camera taken off a wall also takes its built-in storage with it, so a hub or base station is a safer home for footage.
Kit, single or base-station bundle
Titles blur these categories. Some include a HomeBase, some state four cameras, and some say nothing about pack size at all. Open the listing’s “in the box” section and write down what you receive before comparing.
A mounting checklist
- List every spot you want covered: front door, garage, side gate, back door.
- Mark which of those have an outlet within cable reach.
- Note how many hours of direct sun reach the rest.
- Match sunny, outlet-free spots to solar cameras and powered spots to plug-in models.
- Leave one spare slot for the blind spot you will find after the first week.
Worked example: a house with four entry points where only the garage has an outlet suits one C31 there and three solar cameras elsewhere, or a single 4-cam solar kit if all four spots get sun.
Mistakes buyers make
The most common error is assuming a model name tells you what is in the box. A single C37 and a 4-cam C37 kit share branding but not contents. Buyers also forget Wi-Fi range: cameras at the edge of a yard may sit outside the router’s reach. Others overlook that an indoor-only camera will not suit rain, or that solar compatibility does not mean a panel is included.
Verdict
For most outdoor yards, the eufyCam C37 4-Cam Kit looks like the strongest all-round package on paper, with the SoloCam E42 for people who prioritize resolution. The C31 is the easy choice for a powered wall, and the S4 Max is for large properties that want a fuller system. None of this rests on use, so verify the pack contents.

Frequently asked questions
Do Eufy cameras need a monthly subscription?
The listings in this guide state no subscription or no monthly fee, which points to local storage for footage. Some Eufy products may still offer optional cloud services, so read the specific product page to see which features need a plan. Titles describe baseline behavior only, and terms can change, so check the listing before you buy rather than relying on a roundup.
Which Eufy camera works without a power outlet?
The solar models, including the eufyCam C37, SoloCam E42, S340 and E30 listings, are described as solar powered. The C35 is only listed as solar panel compatible, so the panel may be a separate purchase. Plug-in models such as the C31 need an outlet. Solar output varies with sunlight, so shaded walls may struggle to keep the battery charged.
What is the difference between eufyCam and SoloCam?
Going by these titles, SoloCam models are described as standalone cameras with built-in local storage, while eufyCam listings mention kits and, in some cases, a base station. The naming is not always consistent across listings, so rely on the title and the in-the-box section for each product rather than assuming the brand line decides how it connects.
Is the Eufy indoor camera safe to use outside?
Based on its title, the 4K Indoor Camera E30 is designed for indoor spaces such as nurseries and pet areas. It does not mention weather resistance, so do not mount it where it will be exposed to rain or direct sun. For porches and yards, choose a model with an IP rating in the title, like the C35, C31 or the solar SoloCam kits.
How many cameras does a typical house need?
A common starting point is one camera per entry point, so a front door, back door and garage means three, plus extras for a driveway or side gate. Pan-and-tilt models can cover more angle each than fixed cameras. Sketch your property first, then match camera counts to the spots rather than buying the biggest kit.
