eufy SoloCam S340 4-Cam Kit Review: solar security that actually lets you ditch subscriptions

I’ve been slowly moving away from subscription-based cameras, and this eufy SoloCam S340 4-Cam Kit with the HomeBase S380 is the first setup where I felt I could realistically cancel the cloud stuff and not feel half-blind. I ran it side-by-side with a Ring Floodlight and a Blink outdoor cam for a couple of weeks to see if the 3K dual-camera and 360° pan/tilt are just marketing or actually useful day to day.

The short version: it’s a pretty solid all-in-one kit if you want full coverage around a house and you’re tired of monthly fees. It’s not perfect, the app has some annoying quirks, and the 2.4 GHz-only Wi‑Fi is a bit old-school, but for something you buy once and then stop paying for, it holds up well. The solar panels are not magic, but if you place them correctly, you really can avoid climbing a ladder every month.

What stood out for me was the combo of local storage + usable AI features without a subscription. Things like person/vehicle detection and tracking are usually locked behind paywalls on other brands. Here, they’re part of the base deal. That’s a big deal if you’re already paying for a few other subscriptions and you’re tired of adding more.

If you’re expecting a flawless, plug-it-in-and-forget-it system, you’ll be a bit disappointed. Motion detection range at night is weaker than during the day, the app sharing is weird, and the mounts could be better thought out. But if you want good image quality, 360° coverage, and no recurring charges, this kit gets the job done pretty well overall.

Price-wise, this kit sits higher than the usual budget stuff, but you’re getting four PTZ cameras plus a HomeBase with local storage. If you compare it to buying four Ring or Arlo cameras and then paying monthly for cloud storage and smart detection, the math starts to look good after a year or two. The fact that you get person/vehicle detection, AI tracking, and long clips (up to around 60 seconds) without a subscription is where the value really shows up.

For me, the main savings is mental: I’m not juggling another subscription tier or worrying if I’ll lose recordings when a trial runs out. I bought it, I installed it, and that’s basically it. Over time, if you would have paid, say, $10–$15 a month for another brand’s cloud plan, this kit pays for itself. If you’re the type who doesn’t mind subscriptions and you just want the cheapest hardware up front, then this might feel a bit pricey compared to super basic 1080p cameras.

In terms of what you actually get for the cost:

• Pros for value: strong image quality for the price, real 360° coverage per camera, solar + battery so no wiring, and no monthly fees for smart features.
• Cons for value: app is a bit frustrating, 2.4 GHz-only Wi‑Fi feels outdated, and the mounts/solar arms are just okay, not great.

Overall, I’d call the value solid but not mind-blowing. You’re paying a bit more upfront than the bargain brands, but you’re getting better clarity, PTZ, and no recurring costs. Over a couple of years, it makes sense financially, especially if you were going to pay for cloud recording anyway.

The cameras themselves are smaller than they look in photos. Compared to my older bullet-style cameras, the SoloCam S340 units feel more compact and less bulky on the wall. The black-and-white color scheme is pretty neutral, so they don’t scream “industrial camera” from the street, but they’re still clearly visible, which is good if you want a deterrent effect. The dome-ish shape with the pan/tilt hardware gives off a more modern vibe than the usual boxy outdoor cams.

The main design win is the integrated pan/tilt mechanism. You don’t need a motorized mount or anything; the camera body itself rotates. In use, I could swing from the driveway gate to the front door in a couple of seconds right from the app, and the movement is smooth, not jerky. This is a big step up from my static Blink camera that forces you to pick a single angle and live with it. The AI tracking also uses that pan/tilt to follow people or cars, which works decently in daylight.

Now, the downside: the mounting hardware is a bit limited. One of the Amazon reviewers was right: the included bracket is mainly optimized for wall mounting. If you want to mount it under a soffit or a ceiling, you can do it, but it’s not as clean or flexible as it could be. You end up fighting with angles a bit to avoid the camera seeing too much of the wall or eaves. Same for the solar panel: the arm could be longer. If your mounting spot is slightly shaded, it’s tricky to angle the panel into direct sun without it looking odd.

Overall, I like the compact size and the look, and the PTZ design is genuinely practical. But if you’re picky about cable runs, angles, and mounting on rafters or overhangs, you’ll probably swear a bit during installation. It’s not a deal-breaker, just something to be aware of before you plan your mounting spots.

Battery and solar are usually where wireless cameras fall apart, but here it’s pretty decent if you set it up correctly. Each S340 has an internal battery plus a removable solar panel that plugs in with a cable. Over about three weeks, with motion detection set to people/vehicles and a moderate number of events per day (driveway + front door, so not extreme), the cameras with decent sun stayed between 85–100% the whole time. I never had to take them down to charge.

The key is placement. The small solar panel isn’t some huge high-output thing; it needs a few hours of direct sun to keep up. On the camera I put on the north side of the house, which only gets short direct sunlight, the battery slowly drifted down. It didn’t die quickly, but it dropped from 100% to around 70% over two weeks. That lines up with one reviewer who said they only have to manually recharge once every ~6 months for a poorly placed camera. So it’s not “install anywhere and forget forever,” it’s more like “install smartly and mostly forget.”

In terms of raw battery performance, if you disable the solar panel and run just on battery, you’ll be okay for several weeks or a couple of months depending on motion level and how often you view live video. The PTZ tracking and spotlight do consume more power, so if you’re in a busy street with constant motion and you’re hammering the live view, don’t expect miracles. But for a regular suburban house with occasional events, the combo of battery + solar is more than enough.

Charging is via cable when you need it, and that’s the annoying part: you do still need a ladder and a bit of time if one camera isn’t getting enough sun. Personally, I’d say:

• Good sun exposure: basically maintenance-free.
• Partial shade: you’ll probably top up a few times a year.
• Mostly shade: treat it as a standard battery cam and expect regular manual charging.

From a build standpoint, the SoloCam S340 feels solid enough for outdoor use. The housing doesn’t feel cheap or flimsy, and the joints for the pan/tilt don’t wobble. I had a couple of days of pretty heavy rain and some decent wind gusts while testing, and nothing leaked, fogged up, or started acting weird. The lenses stayed clear, and the motors for pan/tilt behaved like normal. It’s not a tank, but it doesn’t feel like something that will fall apart after one season either.

The cameras are rated for outdoor use, and in practice they handled temperature swings fine. I saw no condensation inside the dome or behind the lens, which is something I’ve had with cheaper cameras. The moving parts are always a concern with PTZ designs, but so far I haven’t seen any grinding or misalignment. The rotation is smooth, and the camera doesn’t lose its position. Obviously I can’t simulate two years of use in a few weeks, but based on other user reviews that mention having similar eufy cams for a couple of years with no big issues, I’m reasonably confident it’ll hold up.

The weaker spots are the mounts and solar panel arms. They’re fine, but they don’t feel as overbuilt as some pro-level systems. If you’re in a very windy area or you tend to bump into things with ladders, I’d be a bit careful not to crank the screws too hard or stress the plastic. The solar panel cable also needs a bit of care in routing so it doesn’t flap around or get pinched. Once I tied it down with a couple of extra clips, it felt secure enough.

Overall, I’d call the durability good for a consumer system. It’s not industrial-grade, but for a typical home—rain, sun, some wind, maybe a bit of snow—it should be fine. If you live in an extreme climate (very hot sun all day or heavy coastal storms), I’d just make sure to mount under a bit of cover where possible to give it some extra protection.

On the performance side, the video quality is genuinely good for the price range. During the day, the 3K image is sharp enough that I can clearly read license plates parked in front of the house at around 35–40 feet, and faces are easy to recognize. When the camera switches to the zoomed telephoto view (up to 8×), you obviously lose some brightness and stability, but it’s still much more usable than what I get from my older 1080p cameras. If you care about actually identifying people instead of just seeing blobs, this matters.

Night vision is split into two modes: color with the spotlight on, or black-and-white IR. The black-and-white IR is surprisingly clean: not much noise, and you can make out details like clothing and basic facial features if the person is within 25–30 feet. The complaint from other users is accurate though: motion detection range drops at night. During the day, the camera consistently picked up motion at around 30–40 feet. At night, I often only got notifications when someone was closer, maybe 20–25 feet. So if you need long-range detection in the dark, this isn’t perfect.

The detection filters (people, vehicles, “all motion”) work pretty well. I set one camera to only alert for people and vehicles, and it cut down most of the false alerts from swaying trees. Compared to my Ring, eufy’s AI feels at least as good, maybe a bit better at ignoring random movement. One thing I liked: you don’t need a subscription to get these smart detections. That’s exactly what pushed me away from other brands. I also liked the AI tracking: watching the camera physically follow someone walking across the yard is oddly satisfying and actually useful when you review the clip later.

The weak point is the app. It works, but it’s rough around the edges. Live view loads reasonably fast on Wi‑Fi, a bit slower on 4G, but still okay. The multi-user sharing is clunky: I had the same issue as one of the Amazon reviewers where sharing the system with another resident basically removed the cameras from my account when they tried to add them under theirs. In the end, we just all used one shared login. Also, the app occasionally logs people out, which is annoying when someone wants to quickly check a notification. So performance of the cameras: solid. Performance of the app: usable, but needs work.

This kit is basically a full perimeter setup in one box: four SoloCam S340 cameras plus the HomeBase S380. Each camera is a wireless, battery-powered unit with a small removable solar panel, and the HomeBase sits inside your house plugged into power and your network. All video is stored locally on the HomeBase (and/or internal storage), so you’re not paying for cloud recording every month. That’s the main appeal of this bundle.

Each camera has pan and tilt (PTZ), which is the interesting part. When you mount them vertically on a wall, you can sweep around 360° horizontally and tilt up and down from the app. In practice, that means one camera can cover a wide area: driveway plus sidewalk, or backyard plus side gate, depending on where you put it. Compared to my fixed Blink cams, I needed fewer angles because I could just rotate the S340 instead of installing a second camera.

Resolution-wise, you get 3K video by default, and it can go up to 4K when you’re using AI tracking or dual views. The dual-camera design is there to give you a wide view and a zoomed-in view up to 8× so you can actually see faces or plates at around 40–50 feet if lighting is decent. For context, my Ring footage looks softer when I zoom in on someone at the end of the driveway; the S340 keeps more detail, especially in daylight.

The kit is meant for outdoor use only, runs on 2.4 GHz Wi‑Fi only (no 5 GHz), and is controlled through the eufy Security app on your phone or desktop. There’s Alexa integration if you care about that, but I mostly used the app. Out of the box, the setup is fairly straightforward: plug in the HomeBase, add it in the app, then add each camera one by one. For four cameras, plan around 30–40 minutes if you’re not rushing and you’re also mounting them.
