Choose SoloCam E30 for straightforward tracking and removable-card storage; choose S340 when you repeatedly need a closer view alongside the wider scene. Both can follow activity, so paying for S340 is mainly about its extra lens and viewing options. There is also a less obvious difference: E30's current official FAQ documents continuous recording with direct power, while S340's FAQ explicitly excludes continuous recording.
What does S340 add to the view?
What changes in daily use
| Decision | SoloCam E30 | SoloCam S340 |
|---|---|---|
| Closer view | Zoom: Digital | Hybrid 8× |
| Tracking | With built-in AI and 360° pan, you can get motion-tracking recordings of the detected object, whether a human or a vehicle. | Pans and tilts to follow the action. |
| Standalone storage | SoloCam E30 does not have built-in storage. Recording storage requires a separate SD card (up to 128GB). | Built-In 8 GB EMMC |
| Continuous recording | SoloCam E30 requires direct power connection. | No. Battery cameras aren't currently capable of 24/7 recording, even if connected to HomeBase™ 3. |
The E30 uses digital zoom. S340 combines a wide-angle camera and telephoto camera, and describes a hybrid zoom system. That is a meaningful feature for someone who regularly wants to inspect a farther part of the same yard while keeping the broader scene available.
It is not proof that a face or license plate will be readable at your chosen distance. The viewing angle, movement and lighting still matter. We would pay for the additional lens when closer inspection is a recurring task, not simply because the listing displays a larger resolution number.
Do you need S340 just to follow movement?
No. E30 already documents automatic tracking of humans and vehicles using its pan movement. S340 also pans and tilts to follow activity. If your current problem is repeatedly dragging a static view across the patio, E30 addresses that problem without making the extra lens the starting requirement.
Both need thoughtful placement. A moving camera looks in a particular direction at a particular moment; it does not simultaneously see behind every object around the house. Plan its starting view around the approach that matters most. If opposite entrances need attention at the same time, the camera count and layout may be more important than upgrading a single lens system.
We have not compared their tracking accuracy. These recommendations follow the documented viewing tools, rather than assuming the more elaborate camera follows every person more reliably.
Which model is suitable for a continuous timeline?
The distinction is model-specific. E30's current FAQ says direct power is required for continuous recording. It also requires a microSD card when connected to a router, or the documented storage arrangement when paired with a compatible base. Do not expect the ordinary solar-and-battery placement to provide that same recording mode.
S340's FAQ says it does not support continuous recording, including when connected to the named compatible base. Its solar charging supports the battery-camera workflow; keeping the battery charged does not create an uninterrupted video timeline.
Choose E30's documented direct-power route when the missing information is what happened between triggered events. Choose S340 when event-based viewing with closer inspection is the useful task. Those requirements can outweigh the camera's position in the product range.
How do storage and sunlight affect the purchase?
E30 needs a separately purchased card for standalone recordings. S340 has built-in storage. Both offer a local-storage route without a required monthly recording fee, but check the selected package rather than copying a hub bundle's contents onto a single-camera offer.
Both designs let the panel sit separately from the camera. Use that flexibility: the best view of a gate may be shaded while a nearby panel location receives useful sun. Solar performance varies with weather and recording demand, so keep charging access practical.
For an existing E30 owner, S340 is worthwhile only when the current view regularly lacks the closer perspective you need. If tracking and the current framing already answer your questions, keep it. A replacement adds a feature, not a guarantee of better footage from every mounting point.
What are the checked package prices?
The checked eufy US standard single-camera solar kits list SoloCam E30 at $149.99 and S340 at $199.99. The listed-price difference is $50.00. We would pay it when the documented additional lens and zoom workflow address the view you need, rather than for subscription avoidance that both already offer. Tax, shipping, promotions and optional bundles can change checkout totals.
Watching activity across a patio
Start with E30 if its tracking and card storage fit the job. Reserve money for a suitable card, mounting and power arrangement rather than buying the second lens by default.
Frequently inspecting a farther area
Choose S340 for the documented wide-and-telephoto viewing arrangement when event recording is sufficient. Keep the camera aimed for the actual scene you want to inspect.
Frequently asked questions
Does S340 support continuous recording?
Its current official FAQ says no, including with its compatible base. Do not equate solar charging with continuous video. If an uninterrupted timeline is the requirement, choose a product and power arrangement that explicitly document that mode.
Can SoloCam E30 record continuously on solar power?
The current FAQ requires direct power for continuous recording. It also specifies storage requirements for standalone and base-connected use. A normal solar-and-battery setup should not be purchased on the assumption that it provides the same continuous timeline.
Which camera includes standalone storage?
S340 lists built-in storage, while E30 says a separate microSD card is required. Compare the exact camera kit rather than assuming a card or base shown in a different bundle is included in your offer.
Should I replace E30 with S340 for tracking?
E30 already documents automatic tracking. Upgrade for a specific viewing need, such as wanting the telephoto perspective alongside the wider scene. A new model is less compelling when your existing view and tracking already serve the space.
