What I actually showed
I bought all four Eufy solar cams — E30, E42, S340, S4 — and ran them.
E30 deep dive: Entry pan/tilt solar. Removable solar panel. Daytime 2K. Not a fixed cam — pans/tilts 360° and AI-tracks. Night is infrared black and white — clear range, tracks in low light, no clothing/vehicle color. Motion test: walked in with phone visible so you see when the notification hits; AI flagged me and it tracked across the yard. Audio at 15 ft and 30 ft. Solar wants about 2 hours of direct sun a day. Mid-Michigan, cloudy days. I did not charge it out of the box — set it up and left it, and it’s been on since.
How I priced them in my video: E30 ≈ family movie night with popcorn; E42 ≈ nice dinner for two; S340 ≈ same ballpark as E42 / a few coffees up from E30 when I filmed; S4 ≈ domestic round-trip flight, and I also said about $350 for one S4 — I’d rather buy multiple cams. Check the live listing.
What’s the ranking, worst to best?
4 — E42. Paid S340 money, less camera. No built-in memory — needs microSD or HomeBase 3. Cool lights weren’t enough.
3 — S4. Beast: better picture, track, zoom, color night. Price is the hit. One perfect unit people: your lane. Multi-cam house: maybe not.
2 — E30. Honest upgrade from something like an S220 / small budget. AI tracking, clear IR night, 2K enough, mic surprised me. No onboard storage — budget a HomeBase if you go this route.

1 — S340. Best bang. Color night, 3K, pan/zoom while tracking, 8GB onboard expandable to 32, no HomeBase 3 required. When filmed, roughly E42 money and maybe $10–20 off the E30. That’s why it won.

S340 vs E30 in one glance
S340 — my winner. Color night. 3K. Pan/zoom while it tracks. 8GB onboard, expandable to 32. No HomeBase 3 required.
E30 — honest upgrade from a small budget cam. AI tracking. 2K day. IR night (no clothing/car color). Mic surprised me. No onboard storage — budget a HomeBase if you go this route. Solar wanted about 2 hours of direct sun a day in my video; I didn’t charge it out of the box and it stayed on in mid-Michigan clouds.
If S340 is gone: E30 plus a HomeBase. Don’t buy the E42 just because it’s in the thumbnail.
What if the S340 is sold out?
Look at the E30 plus a HomeBase. Don’t buy the E42 just because it’s in the thumbnail.
Do I pay a monthly fee?
Coolest part of Eufy here: no monthly subscription.
Spec strip
In my video: The E30 gave me a 2K picture by day, IR at night, and a 360 pan-tilt with AI tracking. It wants about 2 hours of sun a day, and I never charged it out of the box. It has stayed on. The E42 has lights and no onboard memory. The S340 has color night, 3K, a tracking zoom and 8GB onboard (expandable to 32GB), and it doesn’t need a HomeBase. The S4 has a higher resolution, better tracking, AI zoom and color night, and I said about $350 for it when I filmed.
Specs from the maker, not my lab meters:
E30: ~3W detachable solar (eufy UK compare) · Wi-Fi 2.4 GHz · HomeKit: no · 2K · microSD (no onboard)
E42: ~3W solar (eufy UK compare) · Wi-Fi 2.4 GHz · HomeKit: yes (eufy lists; often via HomeBase) · 4K · microSD

Who this is for / not
For: someone picking one Eufy solar outdoor cam and wanting bang-for-buck → S340. Small budget / S220 upgrade path → E30 (+ HomeBase). One-and-done beast budget → S4.
Not for: buying the E42 as the “deal” from the thumbnail. Paying monthly to replay your own clips (Eufy path here doesn’t).
How this compares
I bought the E30, E42, S340, and S4 with my own money and ranked them for my wallet, worst to best: E42, S4, E30, S340.

Coolest part in my video: no monthly subscription. When I filmed, I compared the prices to a family movie night, a nice dinner, a few coffees and a domestic flight, and I said about $350 for one S4.

What other reviewers said (their tests — not mine in my video):
- John R. Delaney (PCMag) — Editors’ Choice framing for SoloCam S340: dual-lens 3K wide + 2K tele / 8× hybrid zoom, mechanical pan/tilt + AI track, color night when ambient/spotlight allows, solar panel on the nonremovable battery, 8GB local storage with no required cloud plan; notes it’s pricey and lacks HomeKit / Matter / IFTTT. PCMag: Eufy SoloCam S340 Wireless Outdoor Security Camera Review
- Stephen V. (Sensor & Latch) — picks S340 as a top subscription-free outdoor cam: solar + dual lens + pan/tilt + local onboard (or HomeBase) storage for core record/alert/live/playback with no monthly fee; honest skip if the mount gets no real sun. Sensor & Latch: eufy SoloCam S340 Review
- Simon’s Reviews — After about 18 months on a UK garage roof, the reviewer never took the camera down to charge it, through winter and summer in their sun. They ran it standalone with 8GB of storage, with HomeBase 3 optional. It was still their favorite eufy after two years, with no ongoing subscription for that path. Their weather and sun, not mine. Simon’s Reviews: eufy SoloCam S340 two-year review
Beyond my video:
- Public listings / named reviews talk optional cloud tiers and HomeBase add-ons. In my video the win was local path + no monthly subscription as I framed it — confirm current plan language before you buy.
- If you only want one maxed-out beast and budget isn’t the point, S4 is the one. Multi-cam houses: I’d still start S340 / E30+HomeBase from this video.
Still pick from this video if: you hate monthly fees and want one Eufy solar outdoor cam with bang-for-buck → S340. Small budget / S220 upgrade → E30 (+ HomeBase). Skip E42 as the default thumbnail “deal.” Check the live listing.
FAQ
Which Eufy solar camera should I buy if I hate monthly fees — S340, E30, or skip E42?
I bought the E30, E42, S340, and S4. For my wallet, worst to best: E42, S4, E30, then S340. S340 wins bang-for-buck — color night, 3K, tracking zoom, onboard memory, no HomeBase required. If S340 is gone, E30 plus a HomeBase. Skip buying the E42 just because it’s in the thumbnail. Coolest part: you don’t have to pay a monthly subscription. Check the live listing.
Do I pay a monthly fee on this Eufy path?
No monthly subscription — that’s the coolest part of eufy as I framed it in my video. Clips stay local on the path I used (onboard or HomeBase), not a required cloud plan.
What’s the ranking, worst to best?
4 — E42. 3 — S4. 2 — E30. 1 — S340. S340 is best bang for the buck for me.
Why does S340 win?
Color night vision, 3K, pan and zoom while it’s tracking, built-in memory (8GB expandable to 32), and you don’t even need a HomeBase 3. That combo beat E30 for me when prices were close.
What if the S340 is sold out?
Look at the E30 plus a HomeBase. Don’t buy the E42 just because it’s in the thumbnail.
Why is E42 last?
It cost what I paid for the S340, with less performance, no onboard memory, and it needed a microSD or HomeBase 3. Cool lights weren’t enough.
Does the E30 need a HomeBase? Does it pan?
No onboard storage on E30 — budget a HomeBase if you go that route. And yes, it pans/tilts 360° with AI track — not a fixed cam. ~2 hours direct sun/day in my video; I didn’t charge it out of the box and it stayed on in mid-Michigan clouds.
Is the S4 “better” — should I just buy that?
S4 outperforms on picture, track, zoom, color night. Price is the hit — I said about $350 for one when I filmed, and I’d rather cover more points with multiple cams. One perfect unit people: your lane. Check the listing yourself if that’s your budget.
