Which eufy Solar Camera Fits Your Yard?
The S220 is the simpler fit for one fixed 135-degree area; the S340 adds remote pan/tilt, tracking and two lenses for sites where changing the viewing direction matters. The S340 does not watch every direction simultaneously: eufy describes a 135-degree view at a time and possible brief gaps while panning. Both list 8 GB onboard storage, both can use HomeBase 3 for added local storage, and neither records continuously even with HomeBase 3.

The buying question
Does the S340's moving dual-lens view solve a real placement need, and can either camera provide continuous recording or more onboard storage?
The S220 keeps one fixed 135-degree view with an integrated solar panel; the S340 can pan and tilt between views and has two lenses, but its view is 135 degrees at a time and may briefly gap while moving.
Quick verdict
Choose eufy Security SoloCam S220 if
- One fixed 135-degree view covers the area you need to watch.
- You prefer an integrated solar panel and do not need the camera to change its viewing direction.
Choose eufy Security SoloCam S340 if
- You need to remotely pan or tilt between directions or use the dual-lens views and tracking.
- A removable, separately positionable panel suits the mounting location, and the option you select includes it.
When the recommendation changes
- If continuous 24/7 recording is required, choose neither: eufy says both cameras lack it even with HomeBase 3.
- If the S340's removable panel would solve a mounting problem, check that the package you choose includes it.
The differences that matter
View Adjustment And Lens Configuration
eufy Security SoloCam S220
Fixed 135-degree view; single 2K camera.[1]
What this changes: Fixed framing versus remotely moving between views is a site-layout choice; no coverage or detection superiority is established.[1, 4, 2]
Solar Panel Placement
eufy Security SoloCam S220
Integrated 0.9 W panel.[1]
What this changes: Panel placement flexibility may help when the camera and a sunny mounting spot are in different places; confirm that the option you select still includes the panel.[1, 2, 5]
On Device And Homebase Storage
What this changes: On-device capacity is equal by manufacturer specifications; HomeBase 3 is an added local-storage route for both.[1, 4, 2]
Continuous Recording
eufy Security SoloCam S220
T8134/S220 does not support continuous recording, including with HomeBase 3.[3]
eufy Security SoloCam S340
T8170/S340 does not support continuous recording, including with HomeBase 3.[5]
What this changes: Neither is suitable when continuous 24/7 recording is a non-negotiable requirement.[3, 5]
Best for your routine
A doorway or path where one fixed camera angle covers the priority area and the integrated solar panel fits the mounting site.
Best fit: eufy Security SoloCam S220
Based on listed features, not comparative testing.
The S220's stated 135-degree view stays fixed, avoiding a need to reposition the frame remotely.
A location where the owner needs to redirect the camera between areas or can benefit from its two focal views, with the limitation of a moving 135-degree-at-a-time view.
Best fit: eufy Security SoloCam S340
Based on listed features, not comparative testing.
The S340 adds pan/tilt and a dual-lens setup; this is a feature-fit choice, not evidence of better measured detection or reliability.
A buyer who requires continuous all-day recording.
No clear winner
eufy states neither camera records 24/7 even with HomeBase 3.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
If the S340 costs more at checkout, its pan/tilt, dual-lens arrangement, tracking and flexible panel placement need to solve a real site-layout problem; storage is not a differentiator and neither model supports continuous recording.
Available observations cover only a short dated window and are too brief to assess purchase timing.
Is the upgrade worth it?
Worth considering if
- A mounting site where remote redirection between views solves a real monitoring-layout need.
- A site where the S340's removable panel placement is helpful and the selected option includes the panel.
Skip the upgrade if
- One fixed view covers the target area.
- You expect more onboard storage or continuous recording; neither is established as an S340 advantage.
- The selected offer's panel or other package contents are unclear.
Limitations
- No independent controlled test was used for image quality, detection, tracking, coverage, battery runtime or reliability; the recommendations are feature-fit only.
- The S340 view is 135 degrees at a time and eufy notes possible brief gaps while panning; do not read marketing references to 360-degree pan/tilt as simultaneous all-direction recording.
- The S340's removable panel is a model feature; package contents can vary by offer, so check the in-box list for the option you select.
- eufy's compatibility guide and the S220 US product page conflict about older HomeBase models. This comparison uses only their shared HomeBase 3 compatibility/storage facts.
- Price observations are short-history only; no historical low, savings, or purchase-timing claim is made.
- No hands-on test or owner-community research was conducted.
Questions shoppers ask
Does HomeBase 3 let either camera record 24/7?
No. eufy support says the S220/T8134 and S340/T8170 do not support continuous recording even when connected to HomeBase 3.
Does the S340 see every direction at the same time?
No. Its pan/tilt changes the viewing direction; eufy describes a 135-degree view at a time and possible brief gaps while panning.
Does the S340 have more onboard storage?
No difference is established: both models list 8 GB onboard storage. Both can use HomeBase 3 for expanded local storage.
Does the S340 Solo Cam package include its solar panel?
The Amazon Solo Cam offer checked on September 27, 2026 listed a removable solar panel in the box. Package contents can differ between options, so check the in-box list for the one you select before checkout.
