Eufy SoloCam S340 Review: Dual-Lens Solar Camera With No Fees, but 'No Blind Spots' Oversells It
A sharp dual-lens pan-and-tilt solar camera with strong AI tracking and subscription-free local storage, let down by a misleading blind-spot claim and untrainable false alerts.
The Eufy SoloCam S340 is a wireless, solar-powered outdoor camera with two lenses (a wide view plus a 3x telephoto), 360-degree pan and tilt, AI tracking and no monthly fees. Owners love the sharp picture day and night, the dual-lens coverage that captures wide areas without losing close-up detail, the accurate person, vehicle and animal tracking with cross-camera stitching, and the solar panel that keeps the battery charged even in cloudy or shaded spots. Local storage (8GB built-in or a HomeBase drive) means no subscription and no cloud-hacking worry, and setup is easy. The catches: the 'no blind spots' marketing oversells it, since it only detects motion where the camera is currently pointing (not a true 360-degree sensing like the older E30), you cannot train the AI to ignore false triggers like birds, recordings can cut off mid-event, notifications can only be silenced for 12 hours, and there is no PC viewing. It has no HomeKit. For subscription-free, wire-free dual-lens coverage that keeps footage local, it is a strong pick, just understand what 'no blind spots' really means.

Who is the SoloCam S340 for?
This is a wireless, solar-powered outdoor camera for people who want detailed coverage from one unit with no ongoing fees. Its standout is a dual-lens design, a wide lens plus a 3x telephoto, paired with 360-degree pan and tilt, AI tracking and homeowner recognition. It has a sharp sensor Eufy markets as dual-camera 3K, color and black-and-white night vision, a spotlight, a siren, two-way audio, RTSP and customizable motion zones. It runs on a rechargeable battery topped up by a solar panel, and stores footage locally on 8GB built-in storage or a Eufy HomeBase drive, with an optional cloud plan. It connects over 2.4GHz Wi-Fi and works with Alexa, Google Home and Home Assistant, but not HomeKit, SmartThings or IFTTT. It best suits subscription-free wire-free security, wide-plus-zoomed coverage, existing Eufy HomeBase owners, and shaded or off-grid solar spots. If you need true whole-area motion sensing or trainable AI, read the caveats first.
What buyers love
The dual lens and tracking win owners over. The wide-plus-telephoto setup gives a clear, detailed view of large areas without losing close-up clarity, and the 360-degree pan and tilt lets one camera replace several (one owner went from eight Wyze cameras to four S340s). Picture quality is called sharp day and night with 3x zoom, and AI tracking of people, vehicles and animals is accurate, with homeowner recognition and cross-camera stitching that combines clips from multiple cameras into one video. Solar-plus-battery is a highlight: it charges fast and stays full even in cloudy weather, winter, shade or a north-facing spot, so recharging is a non-issue. There are no monthly fees, with local storage keeping footage private and un-hackable, and setup is easy with helpful in-app guidance. Two-way audio, a spotlight and a siren add security (one owner scared a crane off their koi pond remotely), it is easy to take down for storms, notifications are quick, it integrates with the Eufy ecosystem and Alexa/Google, and kits often include a bonus solar panel.
What to know before you buy
The 'no blind spots' claim is the main disappointment. In practice the S340 only detects motion where the camera is currently pointing, so if you preset it to face one direction, the rest of the yard is effectively a blind spot until something enters the current view, at which point it centers and follows. That is different from the older SoloCam E30, which detects any motion visible to its base and then swivels to track it, a truer no-blind-spot behavior, and the E30 also detects motion farther out and has a brighter floodlight. The S340 will not auto-pan to sweep a wider area either. The AI cannot be trained to ignore false triggers, so bird feeders or a jay on the roof repeatedly flag as a person, and mounted high (around 8 feet) it may not capture enough facial detail to recognize people. Recordings can cut off while a subject is still moving in range, live streaming in the app can lag, notifications can only be silenced for 12 hours at a time (annoying at a vacation property), and there is no way to view feeds on a computer, only the phone app. It uses 2.4GHz Wi-Fi and has no HomeKit.
Is the SoloCam S340 worth it?
For subscription-free, wire-free outdoor coverage with a genuinely useful dual-lens (wide plus zoom), reliable AI tracking and excellent solar battery life, the Eufy SoloCam S340 is a strong-value camera, and most owners are very happy, especially within the Eufy ecosystem. Just buy it understanding the trade-offs: 'no blind spots' really means it tracks what enters its current view rather than sensing the whole area (the older E30 does that better), you cannot teach the AI to ignore birds or feeders, and recordings can end mid-event. Also expect occasional app lag, a 12-hour notification-silence cap, and no PC viewing. Choose it if dual-lens detail, local storage and solar convenience matter most and you can position it toward the area you care about; if you need true area-wide motion sensing, trainable AI, or HomeKit, weigh those limits, or consider the E30, first.
Frequently asked questions
Does it really have no blind spots?
Not in the way it sounds. The S340 only detects motion in the direction the camera is currently pointing, then centers and follows what enters that view, so if you preset it to face one way, the rest of the area is effectively a blind spot. The older SoloCam E30 senses any motion visible to its base and swivels to it, which is closer to true no-blind-spot behavior.
Do I need a subscription?
No. It records locally with no monthly fee, using 8GB of built-in storage or a drive in a Eufy HomeBase, and owners value keeping footage private and off the cloud. An optional cloud plan is available but not required, and most non-subscription features remain fully functional.
How is the battery and solar?
Excellent. The solar panel charges the battery quickly and keeps it topped up even in cloudy weather, winter, shade or a north-facing location, so most owners never manually recharge after the initial charge. Kits often include a bonus solar panel, and the camera is easy to take down for storms.
Can I stop it flagging birds or pets as people?
Not reliably. The AI cannot be trained to ignore specific false triggers, so bird feeders, a jay on the roof or similar motion can repeatedly register as a person. You can adjust motion zones and sensitivity, but there is no way to teach the AI that recurring events are not people.
Does it work with HomeKit?
No. It works with Alexa, Google Home and Home Assistant, but not Apple HomeKit, SmartThings or IFTTT. It also connects over 2.4GHz Wi-Fi only, and there is no option to view live feeds on a computer, everything runs through the phone app.
