No Wi-Fi needed — solid 4G off-grid. Storm night when my Wi-Fi cams died, this one stayed up.
Easy solar attach + few-screw mount. Live feed is a bit delayed; almost-360 (not full) on my unit. Audio latency shows at distance.
Farms, cabins, remote spots. Check the live listing — prices / SIM / plan needs move.
Got a farm, cabin, or construction site with no Wi-Fi? Don’t leave it in the dark. I unboxed the SEHMUA 2K solar 4G LTE camera. Had my doubts — pretty decent so far, with cons. Working completely off the grid, which is pretty much where I live. Solid 4G. Storm night when Wi-Fi cams died, this one stayed up. Check the live listing.
SEHMUA 2K solar 4G LTE security camera — off-grid install I filmed.

What I actually showed
Unbox: docs, solar panel, mounting hardware. Panel is easy to attach — multiple ways, and it can sit farther from the cam. Mount with a few screws. Pre-drill so you don’t wreck them. Snap the cam onto the bracket.
App home / live open — slight delay. D-pad pans up, down, around. Almost-360, then it stops and I reverse. SD on live vs HD on recorded clips. Audio walk at about 50 yards, then about 10–15. Night IR still from the storm stretch.
Does it work with no Wi-Fi?
It’s on 4G. I haven’t found a way to switch it to Wi-Fi — maybe it can’t. That’s a con if you want both. Let me know in the comments if you know otherwise.
Live feed is slightly delayed, but overall pretty good for the camera type. I was watching SD because it’s a live stream — recorded footage can show HD.
4G LTE connection itself has been really solid.
Install and pan
Solar panel attaches easy. Mount is a few screws after pre-drill. Put it together beforehand so the last bit snaps on.
App control panel pans the view. Pretty straightforward. Does not do a full 360 — almost 360, then it stops, and I have to send it the other way. Box can say 360; my unit doesn’t.
Audio, storm win, who it’s for
Audio from about 50 yards, then about 10–15. Pros and cons on latency / talkback response. 4G connection solid.
Thunderstorm that turned into a tornado up the road — this camera was still working when all my other cameras were down because there was no more Wi-Fi.
No camera is perfect. This one ranks pretty high among the random security cams. No huge budget + need a decent HD cam that doesn’t need Wi-Fi → look at SEHMUA. Set and forget somewhere remote.
If you’ve got solid Wi-Fi at the house, this may be the wrong post — see the solar / house-cam sisters below.
Spec strip
Said on camera: SEHMUA (brand on unit; ASR misheard Swann) 2K solar 4G LTE; off-grid; docs + solar panel + mounts; easy panel attach; few-screw mount / pre-drill; 4G only (no Wi-Fi switch found); slight live latency; SD live vs HD recorded; almost-360 pan (not full); D-pad control; audio ~50 yd then ~10–15 yd; latency/talkback cons; solid 4G; storm stay-up when Wi-Fi cams died; remote set-and-forget pitch.
Shown: night IR still during the stay-up stretch (shown, not a lab grade).
Listing: Spec, not a test I ran — current price / SIM / plan needs. Check the live listing. No dollar spoken.
Pros
Works completely off-grid on 4G where I live
Stayed up in a storm when Wi-Fi cams died
Easy solar attach + few-screw mount
Decent live quality for the type; HD on recorded clips
Solid 4G connection
Remote set-and-forget pitch
Cons
No Wi-Fi switch found (4G only for me)
Live feed slightly delayed
Not a true full 360 on my unit
Audio latency / talkback shows the cons at distance
Not a perfect cam — basic remote tool
Who it’s for / not for
For: farms, cabins, construction / remote spots with no Wi-Fi who want a budget-ish 2K solar 4G set-and-forget.
Not for: people who need Wi-Fi + 4G in one body; anyone who needs true continuous 360; anyone chasing zero-latency talkback.
How this compares
I filmed this SEHMUA as a no-Wi-Fi farm / cabin / construction set-and-forget: 2K solar 4G LTE, easy panel + few-screw mount, app D-pad pan that is almost-360 (not continuous on my unit), slight live delay, SD live vs HD recorded, audio walk at ~50 yd then ~10–15 yd with latency/talkback cons, and a solid 4G night when a thunderstorm turned into a tornado up the road and my Wi-Fi cams died while this one stayed up. Had doubts — pretty decent so far, with cons. Price not spoken — check the live listing.
Wi-Fi solar / house lineup (different lane): If you’ve got solid Wi-Fi at the house and you want solar house cams, that’s not this video’s job — use the sisters: Which Eufy solar camera should I buy and Eufy vs Blink vs Wyze. I didn’t run S340 / Blink / Wyze head-to-heads in my video.
SoloCam S220 sun caveat (sister, not this video): For a Wi-Fi solar “set and forget” chicken-coop style pick with the sun/snow honesty, see Does the Eufy SoloCam S220 need 3 hours of sun. Not filmed on this SEHMUA cut.
What other reviewers said (their tests — not mine in my video):
- Rich Nass (Embedded Computing Design) — frames SEHMUA’s 4G LTE solar cam (he names model RBX-S40) for barns / construction / places with no Wi-Fi; separate solar panel for better sun; local TF card up to 128 GB + cheaper cloud option; UBox app straightforward; stresses cellular coverage is mandatory and it isn’t a high-end machine-vision system. Embedded Computing Design: Low-Cost 4G LTE Security Camera Likely Fits the Bill
Beyond my video:
- Listing and other writeups talk cellular SIM trial + paid data plan after trial, cloud trial, and marketing 360°. On my unit I never found a Wi-Fi switch, and pan is almost-360 then stop / reverse — don’t treat box “360” as continuous 360 from my video. Plan dollars = check the live listing; I didn’t lock them in my video.
- If you need Wi-Fi and 4G in one body, or zero-latency talkback, this page isn’t that shootout — stay on the Wi-Fi sisters or keep shopping.
Still pick SEHMUA from my video if: you need a budget-ish 2K solar 4G cam for a remote farm / cabin / site with no Wi-Fi, easy solar mount, and a cam that stayed up when Wi-Fi cams died in a storm. If you’ve got solid house Wi-Fi, use the Eufy / Blink sisters instead. Check the live listing for price / SIM needs.
FAQ
Do you need Wi-Fi for a farm or cabin cam — or will a 4G solar camera stay up? You don’t need Wi-Fi for this one — it’s a 2K solar 4G LTE cam I ran completely off-grid where I live. On a thunderstorm that turned into a tornado up the road, this camera was still working when all my other cameras were down because there was no more Wi-Fi. Solid 4G. Cons exist (live delay, almost-360 not full, audio latency/talkback). Check the live listing for price / plan needs.
Does it need Wi-Fi — or can you switch to Wi-Fi later? No Wi-Fi needed for the job I filmed. It’s on 4G. I haven’t found a way to switch it to Wi-Fi — maybe it can’t. That’s a con if you want both.
Did it stay up in a storm when Wi-Fi cams died? Yes. Thunderstorm → tornado up the road. This camera stayed up; my other cameras were down with no Wi-Fi.
Is it a true full 360? Almost — then it stops, and I reverse direction. My unit isn’t continuous 360 even if the box markets 360.
How’s live video and recorded quality? Live feed is slightly delayed; overall pretty good for the type. I watched SD live; recorded footage showed HD.
How’s audio / talkback at distance? I walked ~50 yards, then ~10–15 yards. There are pros and cons on latency and response time with the audio features.
Is install hard? No. Solar panel attaches easy (can sit farther from the cam). Few screws after pre-drill; put it together beforehand so the last bit snaps on.
Who is this for? Remote set-and-forget — farm, cabin, construction / spots with no Wi-Fi. No huge budget + decent HD that doesn’t need Wi-Fi. Not a perfect cam; ranks pretty high among random security cams I compared it to in my video.
What’s the price / cellular plan? Not spoken in my video. Check the live listing for cam price and any SIM / data plan needs.
