Tapo C660 KIT vs eufy SoloCam S340: Which Fits Your Outdoor Camera Setup?
The advertised 4K/18x and 3K-plus-2K/8x figures do not answer which camera makes better footage; the zoom methods differ and no matched S340/C660 test was found. Pick the C660 KIT for a camera-side microSD workflow with interval snapshots, or the S340 for simultaneous wide and telephoto views plus onboard storage and optional HomeBase expansion. Neither records continuous 24/7 video.

The buying question
Does the C660 KIT's 4K and 18x zoom deliver better image quality than the S340's two-camera, 3K/2K and 8x hybrid-zoom design, and which recording setup is a better fit?
Tapo offers a microSD slot and interval snapshots between motion events; eufy combines wide and telephoto views with on-device storage and optional HomeBase expansion. The published specifications and one-sided Tapo test do not establish an image-quality winner.
Quick verdict
Choose eufy SoloCam S340 if
- You want eufy's simultaneous wide and telephoto camera views in one unit.
- The S340's onboard 8 GB storage is enough for your event-recording routine, or you already plan to use compatible HomeBase S380 storage.
Choose TP-Link Tapo C660 KIT if
- You want a microSD slot on the camera and are willing to buy a card separately.
- Interval snapshots between detected events are useful, and the camera can reach your router on a supported band.
When the recommendation changes
- If the deciding requirement is sharper identification at a particular distance or at night, use matched footage from the intended distance and lighting; these sources do not settle that head-to-head question.
- If continuous video is required, neither camera fits: Tapo's continuous-capture mode takes interval images between events, and eufy says S340 does not support 24/7 recording.
- If the camera is far from the router or the panel must face a different direction from the camera, check Wi-Fi reach and sunlight at each mounting point before buying.
The differences that matter
Lens And Zoom
eufy SoloCam S340
Two views: a 3K wide-angle lens and a 2K telephoto lens, with 8x hybrid zoom.[1]
TP-Link Tapo C660 KIT
One 4K 8 MP sensor with 18x digital zoom.[3]
What this changes: The number and type of lenses describe different ways to frame a scene; 18x digital and 8x hybrid zoom are not directly comparable image-quality scores. TechRadar's C660 review is a single-model test, not a matched S340 comparison, so these sources cannot determine which records clearer faces or plates at a buyer's distance.[1, 3, 5]
Storage Workflow
eufy SoloCam S340
The S340 has 8 GB of onboard storage and can use HomeBase S380 storage when paired; eufy says the S340 does not support 24/7 recording, even with HomeBase.[1, 2]
TP-Link Tapo C660 KIT
The C660 KIT accepts a microSD card up to 512 GB, sold separately. Its 24/7 Continuous Capture setting takes images at chosen intervals between object detections, then switches to standard video recording when an object is detected.[3]
What this changes: Compare the recording format and the extra storage hardware you will actually buy, not just the maximum capacity. Neither feature set supplies continuous video: Tapo's between-event record is interval imagery, while eufy explicitly rules out 24/7 recording for the S340.[1, 2, 3]
Solar Placement
eufy SoloCam S340
The S340's included panel can be mounted on the camera or nearby by cable; eufy says charge collected depends on sunlight and weather.[2]
TP-Link Tapo C660 KIT
The C660 KIT includes a Tapo A201 panel with an extension wire. TP-Link lists 2.5 W maximum charging power and says its 45-minute sunlight estimate uses specified test conditions and up to 100 events per day. A months-long independent C660 review reported that overcast days affected charge and interval capture strained the panel in that installation.[3, 5]
What this changes: Panel ratings and manufacturer sunlight estimates use different conditions, while the independent C660 observation is one installation. Choose by checking usable sun for the panel and signal at the camera location; these data do not prove which camera has greater real-world solar autonomy.[2, 3, 5]
Network Fit
eufy SoloCam S340
The S340 uses 2.4 GHz Wi-Fi.[4]
TP-Link Tapo C660 KIT
The C660 KIT supports 2.4 and 5 GHz Wi-Fi; TP-Link notes that 5 GHz has shorter range than 2.4 GHz.[3]
What this changes: The extra band is useful only if the camera location has a usable 5 GHz signal. Check the installed location rather than treating dual-band support as an automatic range advantage.[4, 3]
Best for your routine
Adding local storage directly to the camera and reviewing interval images between detected events
Best fit: TP-Link Tapo C660 KIT
Based on listed features, not comparative testing.
The C660 KIT has a camera-side microSD slot up to 512 GB and configurable interval-image capture; the card is an extra purchase.
Keeping a broad scene and a telephoto view available together
Best fit: eufy SoloCam S340
Based on listed features, not comparative testing.
The S340 uses separate wide-angle and telephoto cameras; this is a framing advantage, not proof of sharper image quality.
Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Compare the live offer for the exact one-camera S340 and C660 KIT variants, including the separate microSD or HomeBase equipment you intend to add. No stable premium conclusion is embedded here.
Insufficient price history to advise on purchase timing; compare the current offer and included kit contents before deciding.
Limitations
- No matched, controlled S340 and C660 KIT image test was found; the image-quality winner remains unproven.
- TechRadar's C660 KIT observations are one installation and do not establish comparative solar performance against the S340.
- Official solar sunlight estimates specify different conditions and are not a common test.
- The S340's HomeBase S380 storage option is a separate system purchase; verify the current firmware requirement and the exact Amazon bundle before purchase.
- Confirm the selected Amazon variant is the one-camera SoloCam S340 with solar panel before purchase; this research did not bridge the catalog part suffix to the selected Amazon offer.
Questions shoppers ask
Does 18x zoom mean the Tapo will capture clearer detail than the S340?
No conclusion follows from those multipliers. Tapo lists 18x digital zoom; eufy lists 8x hybrid zoom across wide and telephoto cameras. One independent C660 test cannot establish a winner against an untested S340 sample under the same scene and lighting.
Can either camera continuously record video around the clock?
The S340 does not support 24/7 recording. Tapo's 24/7 Continuous Capture takes interval images between detections, then records video when an object is detected; that is not continuous video either.
Can the S340's storage be expanded?
Eufy says the S340 can use HomeBase S380 storage, subject to the supported firmware requirement. The C660 instead accepts a separately purchased microSD card directly in the camera.
Methodology and sources
Matched each material statement to the exact product-side source, separated official feature claims from one-sided independent observation, and left image-quality and solar-autonomy leadership unresolved without a matched test.
AI assisted in organizing live source research and drafting; no Pickoryx hands-on testing or performance measurement was conducted.
