The C37 is the fit if its listed 2K/127-degree view meets your framing needs and you want to choose a separate microSD card for standalone recording. The S340 is the fit if you want its wide/telephoto lens setup with hybrid 8x zoom or built-in 8GB storage. Manufacturer specifications do not establish real-world image quality or coverage at your property.

The buying question

Should you choose the C37 or S340 for the capture configuration and local storage workflow you want?

C37 is listed with 2K capture and card-based standalone storage, while S340 has two lens views, hybrid zoom and built-in local storage; neither specification establishes footage quality at a particular home.

Quick verdict

Choose eufyCam C37 (T814X, White) if

  • The C37's listed 2K resolution and 127-degree field of view suit your planned view, and you prefer to select a microSD card for standalone recording.
  • You would rather decide the microSD capacity yourself than rely only on the S340's listed built-in 8GB local storage.

Choose eufy SoloCam S340 (T8170 / T81701W1, White) if

  • You want the S340's documented wide-angle 3K and telephoto 2K views with hybrid 8x zoom.
  • Built-in 8GB local storage and the option to use HomeBase S380 storage are a better match for your setup.

When to skip: Continuous 24/7 recording is essential; eufy says neither camera supports it.
When the recommendation changes
  • If your priority is a listed dual-lens 3K wide-angle and 2K telephoto setup with hybrid 8x zoom, S340 is the feature-fit; the specifications do not prove better recorded footage.
  • If you want to choose a separately sold microSD card for C37 standalone recording, C37 offers that documented workflow; S340 instead has listed built-in 8GB storage and optional HomeBase S380 use.
  • If continuous 24/7 recording is required, neither model fits: eufy says these battery cameras do not support continuous recording.

The differences that matter

Coverage And Capture Configuration

eufyCam C37 (T814X, White)

eufy lists the C37 at 2K resolution and a 127-degree field of view; its US product page also describes 360-degree pan and tilt.[1]

eufy SoloCam S340 (T8170 / T81701W1, White)

eufy describes the S340 as a dual-camera design with a 3K wide-angle lens, a 2K telephoto lens and hybrid 8x zoom; the maker's comparison table lists a 135-degree field of view.[1, 2]

What this changes: Choose by the capture configuration you want: S340 documents separate wide and telephoto views plus hybrid zoom; C37's listed resolution and field of view may be enough for a buyer's planned framing. These specifications do not demonstrate sharper footage, readable faces or plates, or superior coverage at a particular property.[1, 2]

The better fit depends on your priorities

Local Recording And Storage Workflow

eufyCam C37 (T814X, White)

C37 has no built-in storage. For standalone recording, eufy says to add a separately sold microSD card, up to 256GB; the product page also lists HomeBase as an option.[1]

eufy SoloCam S340 (T8170 / T81701W1, White)

The eufy comparison table lists built-in 8GB eMMC storage for S340. Its US product page says the camera can use HomeBase S380 storage when connected; the listed compatibility requirement is firmware V3.3.2.6 or later.[1, 2]

What this changes: C37's standalone recording requires a separate card, while S340 has 8GB onboard and an optional HomeBase S380 storage path. Pick the workflow that fits your preferred setup; confirm the current HomeBase model and firmware before buying it.[1, 2]

The better fit depends on your priorities

Best for your routine

Based on listed features, not comparative testing.

eufy says standalone C37 recording needs a separately sold microSD card, with capacity up to 256GB; its published camera specifications list 2K and 127 degrees. This does not establish a footage-quality result.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Prices change. Compare any current price difference with the S340's documented dual-lens/zoom configuration and built-in 8GB storage; those features may matter to some setups but do not make it the right choice for every buyer.

Available price observations are current snapshots only and do not provide a long-term history window.

Limitations

  • No hands-on or controlled image, tracking, detection, night-vision or reliability testing was conducted. Manufacturer specifications do not predict results at a specific property.
  • C37 standalone recording requires a separately sold microSD card; confirm the exact listing's included accessories before purchase.
  • S340's built-in local storage is listed as 8GB. HomeBase S380 storage is optional and requires the listed firmware level; its capacity and purchase cost are not included here.
  • Neither camera supports 24/7 continuous recording according to eufy's product/support information.
  • Catalog prices and availability can change; this article does not state a price history or buying-time recommendation.

Questions shoppers ask

Does the eufyCam C37 need a microSD card?

For standalone recording, yes. eufy says the C37 has no built-in storage and that recording is unavailable without a separately sold microSD card; the product page lists support up to 256GB. It also lists HomeBase as another storage option.

Can the SoloCam S340 save footage locally without HomeBase?

eufy's comparison table lists built-in 8GB eMMC storage for the S340. Its US product page says a connected HomeBase S380 can provide additional storage; the page lists firmware V3.3.2.6 or later for compatibility.

Do either of these cameras record continuously around the clock?

No. eufy's C37 page says continuous 24/7 recording is not supported, and its S340 FAQ says battery cameras do not support 24/7 recording even with HomeBase 3.

Does S340's 8x zoom mean its footage will be clearer?

It means eufy documents hybrid 8x zoom for S340; the published specifications do not establish comparative clarity or how readable a distant object will be in your installation.
