What Is the eufy SoloCam E30?

Last update on 2026-06-09 / Affiliate links / Images from Amazon Product Advertising API

The eufy SoloCam E30 is a solar powered outdoor camera. It shoots 2K video day and night. It spins a full 360° and tilts 70°. This means it can watch every corner of your porch, yard, or driveway.

The E30 uses a single lens with an f/1.6 aperture. That wide aperture pulls in more light. So your night footage stays sharper and cleaner. You get clear color video when you add the spotlight.

Battery life is a strong point here. A removable solar panel keeps the camera charged. eufy says just 2 hours of daily sun keeps it running. You can detach the panel and mount it where the sun hits best. This flexibility helps homes with shady walls.

Storage is simple and private. You drop in a microSD card up to 128GB. Your footage stays local with no monthly fee. You never pay a cloud bill to view your clips.

The E30 also works with the HomeBase S380 and S280. That upgrade unlocks smarter AI and larger storage. Built in AI detects and tracks people, cars, and events. This cuts false alarms from swaying trees or shadows.

At around $99.99, the E30 is a smart budget buy. It covers the basics well and adds solar power on top.

What Is the eufy SoloCam S340?

Last update on 2026-06-09 / Affiliate links / Images from Amazon Product Advertising API

The eufy SoloCam S340 is the dual lens flagship. It packs a 3K wide camera and a 2K telephoto camera. Together they give you a wide view plus close detail. This combo is the main reason to pick the S340.

The wide camera covers your whole scene at 3K resolution. The telephoto lens zooms in up to 8x. So you can read a license plate or spot a face far away. You switch lenses right inside the app during live view.

Like the E30, the S340 pans 360° and tilts 70°. AI motion tracking follows movement smoothly. The camera keeps the subject in frame from start to finish. Reviewers praise the smooth tracking with little blur.

The solar panel keeps it topped up. Two hours of sun a day is enough in most seasons. You can attach the panel to the top or extend it with a cable. This lets you place the camera in shade and the panel in sun.

Storage works differently here. The S340 has 8GB built in and no microSD slot. That fills up faster than a card. For more space, you connect it to a eufy HomeBase. The HomeBase also adds facial recognition.

At about $139.99, the S340 costs more. You pay extra for the second lens and the zoom power.

The eufy SoloCam S40 is a fixed lens solar camera. It shoots 2K video and skips the pan and tilt motors. This makes it cheaper and simpler for a single fixed view. Choose it if you only need to watch one spot.

The eufy SoloCam S220 is a great value fixed camera. It offers 2K video, solar charging, and 8GB built in. It runs on continuous solar power with no monthly fee. This is a smart pick for a tight budget.

The eufyCam E40 works as an add on camera for a system. It brings 2K MaxColor night vision and an integrated solar panel. It pairs with HomeBase 3 for local storage. Pick it if you want to expand a full eufy setup.

Video Quality Compared

Video quality is where these two cameras split apart. The S340 shoots 3K on its main lens. The E30 shoots 2K. That gap gives the S340 sharper wide shots with more detail.

In daylight, both cameras look great. The E30 delivers clean, well exposed 2K footage. Faces and shapes are easy to spot up close. For most porch and yard use, 2K is plenty sharp.

The S340 pulls ahead at distance. Its 3K sensor holds detail better across a large yard. When you crop or zoom, the extra pixels help a lot. This matters if you watch a driveway or long path.

At night, both cameras do well. Each uses IR for black and white footage. Each also offers full color night mode with the spotlight on. The wide f/1.6 aperture on both helps low light shots.

One note on the S340. Its dual mode records both lenses at once. This mode drops overall image quality. Reviewers suggest you skip dual mode and switch lenses live instead.

So the winner depends on your view. For close range, the E30 looks nearly as good. For wide yards and detail, the S340 wins clearly. The 3K sensor is the deciding edge.

Zoom and Dual Lens Power

This section is the S340’s biggest strength. The S340 carries a real telephoto lens. It zooms up to 8x with true optical reach on the second camera. The E30 has no telephoto lens at all.

The E30 relies on digital zoom only. Digital zoom just crops and enlarges the image. This softens the picture the more you zoom in. So distant details blur on the E30.

The S340’s telephoto lens keeps distant subjects sharp. You can read small text or spot faces far off. This helps you watch a gate, a mailbox, or a street. You get usable detail where the E30 falls short.

You switch between the wide and telephoto view in the app. During live view, one tap moves you to the zoomed lens. This makes checking a specific spot fast and clear.

If you have a large property, this lens is worth the price. It turns one camera into two useful views. For big yards, the S340 zoom is a game changer.

If you have a small porch, you may never need zoom. In that case, the E30 saves you money. The dual lens is only worth it if you use it.

Solar Power and Battery Life

Both cameras run on the sun. Both need just 2 hours of daily sunlight to stay charged. This means little to no manual charging in most seasons.

The E30 uses a removable solar panel. You can detach the panel from the camera body. Then you mount it wherever the sun hits hardest. This split design helps homes with shaded walls.

The S340 attaches its panel to the top of the camera. You angle the panel toward the sun. eufy also includes an extension cable in the box. So you can mount the panel away from the camera if needed.

Both approaches work well. The key is giving the panel real sun each day. Place either camera on a bright, south facing wall for best results. Winter sun may need a top up charge in cold regions.

Battery drain depends on activity. A busy street view triggers many recordings. That drains the battery faster on both models. Set a smart home position to avoid busy areas.

For solar flexibility, the E30’s removable panel wins slightly. It gives you more freedom in shady yards. Both cameras deliver strong solar performance overall.

Storage Options and Privacy

Storage is a clear win for the E30. The E30 accepts a microSD card up to 128GB. You buy the card size you want and expand as needed. Your clips stay local and private with no cloud fee.

The S340 has only 8GB built in. Worse, it has no microSD card slot. That small space fills up fast with frequent recordings. You cannot swap in a bigger card later.

This is a real limit for the S340. To get more space, you must add a eufy HomeBase. The HomeBase lets you attach a hard drive or SSD. That upgrade costs extra money and setup time.

Both cameras keep footage local by default. Neither forces a monthly subscription. This saves you money over cloud based rivals across the years.

The HomeBase adds bonus features on both cameras. It unlocks facial recognition and larger local storage. The E30 works with the S380 and S280 bases.

For storage freedom, the E30 is the clear pick. Its microSD slot beats the S340’s fixed 8GB. If you record a lot, the E30 is easier to live with.

AI Detection and Smart Tracking

Both cameras use smart AI to cut false alarms. Each one detects people, pets, and vehicles. This helps you ignore swaying branches and passing shadows.

AI motion tracking is a highlight on both. When motion starts, the camera pans to follow. It keeps the subject in frame from start to end. So your clips capture the full event, not just a piece.

Reviewers say the S340 tracking is smooth. It moves without the judder seen on rival cameras. The E30 offers the same smart tracking with its AI chip.

You can set activity zones on both cameras. Only motion inside your chosen zone triggers a recording. This cuts down on useless alerts from the street.

Both cameras return to a home position after events. This keeps the lens aimed at your key area. Without it, a camera could end up facing the ground.

Add a HomeBase and detection gets smarter. Facial recognition tags clips with known faces. Both cameras handle AI detection very well. This round is nearly a tie.

Installation and Design

Both cameras are easy to install. Each one mounts to a wall or a ceiling overhang. You charge the battery first, then attach the solar panel.

The S340 is chunkier due to its dual lenses and motors. It sticks out more from the wall. Mount it high so the tilt can angle down at people.

The E30 has a slimmer single lens body. Its removable panel gives you more mounting options. You can place the camera in one spot and the panel in another.

Both use the eufy Security app for setup. You connect to your 2.4GHz Wi-Fi network. Note that neither camera supports 5GHz Wi-Fi. Keep your router band in mind before you buy.

Both cameras are built for the outdoors. They handle rain and sun with weather resistant designs. Place them under a slight overhang for extra life.

Setup takes only a few minutes for either model. The app walks you through each step. Both cameras score well on easy install.

Smart Home and App Features

Both cameras plug into popular smart home systems. Each works with Amazon Alexa and Google Home. You can stream a feed to a smart display with your voice.

The eufy Security app runs both cameras. You view live feeds, clips, and settings in one place. The Events tab sorts clips by date, device, and motion type. This makes finding a clip quick and simple.

You control when each camera records with modes. Home, Away, and Disarmed modes set which lenses run. You can schedule modes or trigger them by location.

The S340 lets you set preset camera positions. You tap a preset to jump to a saved view fast. This is handy with the dual lens setup.

One small gap exists. Neither camera supports IFTTT automation. So you cannot link modes to other smart devices easily.

Both cameras deliver a smooth app experience. The features are close between the two models. The S340 edges ahead with its preset positions.

Price and Value

Price is where the E30 shines. It sells for about $99.99 and drops during sales. That is a strong deal for a solar pan and tilt camera.

The S340 costs around $139.99. You pay roughly $40 more for the second lens. That extra buys you 3K video and 8x zoom power.

Value depends on your needs. If you want simple wide coverage, the E30 wins. It gives you most of the same features for less money. The microSD slot adds long term savings too.

If you need zoom and detail, the S340 earns its price. The telephoto lens does real work in big yards. That feature alone can justify the higher cost.

Both cameras skip the monthly fee. This saves you money for years compared to cloud cameras. Your footage stays local and private on both.

For pure value, the E30 is the better deal. For premium features, the S340 is worth the stretch. Match the price to how you plan to use it.

Verdict: Which eufy Camera Should You Buy?

Both cameras are excellent solar picks with no monthly fee. Your best choice comes down to zoom needs and budget.

Buy the eufy SoloCam E30 if you want value. It costs less at around $99.99. It gives you 2K video, 360° pan, and 70° tilt. The removable solar panel and microSD slot are big wins. This is the smart pick for porches, small yards, and tight budgets.

Buy the eufy SoloCam S340 if you want detail. It brings a 3K main lens and a 2K telephoto lens. The 8x zoom spots faces and plates far away. This is the right camera for large yards, long driveways, and gates. You pay more, but the dual lens earns its keep.

In short, the E30 wins on value and storage. The S340 wins on zoom and video quality. Pick the E30 for everyday coverage. Pick the S340 for long range detail work.
