Eufy SoloCam S340 Review 2026: Should You Buy This?

Outdoor cameras often fail in the same ways. The battery dies, the view has blind spots, or the monthly fees pile up.

The Eufy SoloCam S340 tries to fix all three problems. It has two lenses, a motor that spins the camera, and a solar panel that keeps it charged.

I looked at the specs, expert tests, and owner feedback from 2026. This review covers what works and what does not. Read on to see whether this camera fits your home.

In a Nutshell

• Two lenses in one camera. The wide lens records 3K video with a 135 degree view. The telephoto lens records 2K video and zooms up to 8x. You get both the big picture and the close detail.
• 360 degree pan and 70 degree tilt. The motor moves the camera to cover your whole yard. Blind spots shrink a lot compared to fixed cameras.
• Solar power keeps it running. The 2.2W panel tops up the battery daily. Without the panel, the battery lasts about three months.
• No monthly fee. The camera has 8GB of built in storage. You keep your clips without paying for a cloud plan.
• AI tracking follows people and vehicles. The camera spots a target and moves to keep it in view. It also sends alerts to your phone.
• The price sits on the higher side. Expect to pay roughly $160 to $200 depending on sales. Most buyers find the features worth it.

Eufy SoloCam S340 Overview

Last update on 2026-10-26 / Affiliate links / Images from Amazon Product Advertising API

The Eufy SoloCam S340 is a wireless outdoor security camera. It runs on a battery and charges through a small solar panel. You can mount it almost anywhere without running a power cable.

The S340 stands out because of its dual lens design. One lens shows a wide view of your property. The second lens zooms in on faces, plates, or packages.

The camera also moves. A motor pans it a full circle and tilts it up and down. One camera can do the work of two or three fixed cameras.

PCMag gave the S340 an Editors’ Choice award. The reviewer praised the sharp video, the free local storage, and the smooth pan and tilt motion.

Owners report good results too. A user who tested the camera for two and a half years said it still tracks well and pans at a decent speed.

This review covers the design, video quality, night vision, tracking, battery, setup, and price. You will also see three alternatives and a final verdict.

Design and Build Quality

The S340 has a white body and a round black camera head. The head hangs below the main housing. It looks clean and does not draw much attention on a wall or post.

The camera has an IP67 weather rating. Dust and heavy rain should not harm it. Eufy lists the working temperature range as minus 4°F to 140°F.

The solar panel clips onto the top of the camera. It measures about 4.7 by 4.7 inches. You can also remove it and place it somewhere sunnier.

Eufy includes a 10 foot USB C cable for that purpose. This is handy if your camera sits under a roof or in shade.

The back of the camera has a USB C charging port and a sync button. A small LED on the front shows the charging status. It glows blue while the battery charges.

The mount is simple. You screw the bracket to a wall, fence, or post. Then you slide the camera into place.

The build feels solid in the hand. The motor is quiet, and the housing does not creak. For a camera that lives outside, that matters.

Dual Lens Camera and Video Quality

Video quality is the best part of the S340. The wide lens records at 3K resolution, which is 2880 by 1620 pixels. It covers a 135 degree field of view.

The second lens is a telephoto lens. It records at 2K and supports 8x hybrid zoom. Eufy lists a clear detail range of about 50 feet.

In the app, you see both lenses stacked on the screen. The top view shows the wide scene. The bottom view shows the zoomed close up.

PCMag tested the camera in a backyard. The reviewer found that both lenses gave highly detailed and colorful video. The zoom lens gave a sharp look at the target area.

There is one catch. The Ambient review noted that dual mode lowers image quality a bit. You may want to pick a single lens view when you need the sharpest picture.

Daytime color looks natural and clean. Faces and license plates stay readable at a fair distance. Packages on a porch are easy to see.

The zoom lens is the feature that sets this camera apart. Most cameras in this price range only offer one fixed lens.

Night Vision and Spotlight

Night footage matters as much as day footage. Most break ins happen after dark. So I checked how the S340 handles low light.

The wide lens has an f/1.6 aperture. Eufy says it captures 20 percent more light. Color night vision works up to about 26 feet when ambient light is present.

When the area is too dark, the camera switches to black and white. PCMag found that black and white night video looked crisp and well lit. It also showed good contrast.

Color night video was a different story. The reviewer called it a bit dull. A cheap wired camera showed richer night colors in the same test.

The built in spotlight helps here. It puts out 100 lumens and turns on when the camera senses motion. The light also acts as a warning for anyone who lurks near your door.

The siren adds another layer. It reaches 90 dB, which is loud enough to catch attention on a quiet street. You can trigger it by hand from the app too.

Night performance is good, not perfect. Place the camera near a porch light or street light for the best color footage.

Top 3 Alternative for Eufy SoloCam S340

The S340 is a strong pick. But other cameras may suit your budget or setup better. Here are three options worth a look.

The Eufy SoloCam S230 is a cheaper solar camera. It records 3K video and supports solar charging. It does not have the dual lens or the pan and tilt motor.

The Eufy Floodlight Camera E340 shares the dual lens idea. It adds a 2,000 lumen floodlight and 360 degree pan and tilt. It needs wired power, so it suits homes with an existing outdoor electrical box.

The Ring Spotlight Cam Pro is a good choice if you like the Ring app. It offers advanced 3D motion detection and dual band WiFi. Ring locks some features behind a paid plan, and the camera has no pan and tilt motor.

Pick the S230 for a lower price. Pick the E340 for wired power and bright light. Pick the Ring if you already use Ring devices.

Pan, Tilt, and AI Tracking

The motor is a big reason to buy the S340. It spins the camera 360 degrees on the horizontal axis. It tilts 70 degrees up and down.

You control the movement from the app. A four way pad lets you steer the view. You can also save up to four preset positions and jump to them with one tap.

The 360 degree round look button is a neat trick. The camera does one full spin and then returns to its start point. It gives you a quick scan of your whole yard.

AI tracking is the star feature. The camera spots a person or vehicle and follows it. It pans, tilts, and zooms to keep the target in frame.

PCMag said motion tracking worked flawlessly in testing. The pan and tilt motion was smooth too.

Owners agree. One long term user said tracking still works well after more than two years.

Face recognition and pet detection need extra hardware. You must add a HomeBase hub for those functions. The camera alone handles person and vehicle detection.

The tracking cuts down on false alerts. It also gives you better clips of what actually happened.

Solar Power and Battery Life

Solar charging keeps the S340 running without any chores. The panel is a 2.2W unit. Eufy says two hours of good sunshine can power the camera for a full day.

The numbers are simple. In good light, the panel stores 800 to 1,200 mAh per day. The camera uses only 100 to 200 mAh in an average day and night.

That leaves a healthy surplus. The battery should stay full in sunny places.

Eufy calls its panel technology SolarPlus. The company says the panel converts up to 25 percent of sunlight into energy. Eufy claims this beats typical rivals by a wide margin.

You can skip the panel if you want. The battery then lasts up to three months per charge, based on normal use. You recharge it through the USB C port.

Winter is the weak spot. Short days and cloudy skies cut the solar income. One owner who tested the camera for years flagged winter solar performance as a point to watch.

You can fix this with placement. Mount the panel on a south facing wall or use the extension cable. A sunny spot makes a big difference.

The app shows weekly and monthly solar charging data. You can see if your panel gets enough light.

Setup and the Eufy Security App

Setup is quick. PCMag had the camera running in minutes. Eufy says the install takes about five minutes.

You charge the battery first. Then you download the Eufy Security app on Android or iOS. You add the device and pick the SoloCam S340 from the battery camera list.

Next, you connect the camera to your WiFi. The S340 works on the 2.4GHz band. Make sure your router offers it.

The app then shows a QR code. You hold it up to the camera. Two beeps confirm the link.

After pairing, you name the camera and choose a power plan. The options include optimal battery life and optimal surveillance. You can also set custom recording lengths.

The app runs a WiFi signal test at the mounting spot. That test saves you from a bad install. Run it before you drill any holes.

The main screen is easy to read. You get live view, two way talk, a light button, and a record button. Settings cover activity zones, privacy zones, motion sensitivity, and spotlight brightness.

The app has many options. New users may need a few minutes to learn the layout. After that, daily use feels simple.

Storage, Privacy, and Smart Home Support

The S340 stores clips on 8GB of built in memory. You pay nothing each month. That is a major win over camera brands that charge for video history.

The tradeoff is capacity. 8GB fills up over time, and the camera overwrites old clips. Cloud storage is not offered.

You can expand storage with the HomeBase S380 hub. It supports external drives up to 16TB. The hub also unlocks facial recognition and more accurate alerts.

Eufy lists the hub’s AI accuracy at 95 percent. The hub adds cost. PCMag listed the earlier HomeBase 3 at $149.99.

Privacy is a plus. Your clips stay on the device or on your own hub. You choose whether to use any cloud based features.

Smart home support covers the basics. The S340 works with Amazon Alexa and Google Assistant. You can ask an Echo Show to stream the camera feed.

PCMag tested an Alexa routine that turned a smart bulb red on motion. It worked without a problem.

Apple HomeKit, IFTTT, and Matter are not supported. Apple households may find this limiting.

Pros and Cons

Every camera has strengths and weak spots. Here is a clear summary of the S340.

Pros:

• Dual lens setup gives a wide 3K view and a 2K zoom view in one device.
• The 360 degree pan and 70 degree tilt motor removes most blind spots.
• AI tracking follows people and vehicles smoothly and accurately.
• Solar panel keeps the battery charged in sunny locations.
• No monthly fee, and 8GB of local storage comes built in.
• The 100 lumen spotlight and 90 dB siren help scare off intruders.
• Setup takes about five minutes with the app.

Cons:

• Color night video looks a bit dull compared to some cheaper cameras.
• Dual view mode lowers image quality slightly.
• The camera only works on 2.4GHz WiFi.
• Face recognition and pet detection need a separate HomeBase hub.
• Winter sunlight may limit solar charging.
• No Apple HomeKit or Matter support.
• The price is higher than many single lens cameras.

Final Verdict: Is the Eufy SoloCam S340 Worth Buying?

Last update on 2026-10-26 / Affiliate links / Images from Amazon Product Advertising API

The Eufy SoloCam S340 is one of the best solar security cameras you can buy in 2026. It offers sharp video, smart tracking, and a motor that covers your whole yard. All of that comes without a monthly fee.

The dual lens design is the biggest draw. You see the wide scene and the fine detail at the same time. Few cameras at this price do that.

Buy it if you have a large yard, a driveway, or several entry points. One S340 can replace two fixed cameras. The solar panel saves you from regular battery swaps.

Skip it if you rely on Apple HomeKit. Skip it too if you live somewhere with weak sun and long winters. In those cases, a wired camera like the Floodlight E340 may fit better.

Watch for sales. The camera has dropped to about $160 at times. At that price, the value is excellent.

I rate the S340 4.5 out of 5. It is a reliable camera that keeps working year after year, and most owners will be happy with it.
