What it costs to keep it running

A rough budget for the first 3 years of upkeep, based on what owners said in reviews and what replacement parts sell for online.

Projected 3-year upkeep cost

$5

How we estimated the upkeep number

This figure is the estimated cost for replacement parts, repair shipping overhead, and common mechanical component failures over a 36-month horizon, based on real community feedback and secondary-market part prices.

Repairs look manageable

Community reports suggest replacement parts and repairs should stay modest over the next three years.

Longer notes from the same comments we summarized above.

What people reported

The Eufy SoloCam S40 is generally described as easy to set up with an intuitive app interface. Owners appreciate the solar-powered aspect, noting that it charges well in good sunlight. The camera offers full-color night vision and the flexibility to use either a spotlight or infrared (IR) for nighttime recording. Many users value the convenience of not needing to run wires for power, and it can integrate with Alexa for routines.

Problems people mention

A recurring concern for the SoloCam S40 is unexpected battery drain, with some cameras dying quickly even when the solar panel is actively charging. Durability issues are also frequently cited, including the top layer of the solar panel flaking, discoloration and water ingress into the housing, and permanent spots on the lens leading to foggy or blurry video, especially in humid conditions. Owners in rainy climates report routine failures after only about six months. Some users found the human detection to be slow, allowing trespassers to pass by before being fully captured. The camera also lacks 24/7 continuous recording; it only provides short event clips and does not offer a timeline-style playback bar. If the camera is stolen, all footage recorded on the device is lost, as it cannot connect to an NVR.

Where owners disagree

There isn't significant disagreement on core features, but rather varying experiences with performance. While some praise the solar charging, others find it inconsistent, particularly in cloudy weather or during winter when sun exposure changes. WiFi range is also a point of concern, with users questioning if the camera will work at distances like 80 or 100 feet from their home router, suggesting it needs to be within good home Wi-Fi range.

Who it's for

The Eufy SoloCam S40 is best suited for users looking for a wire-free, solar-powered security camera in consistently sunny, dry climates where continuous 24/7 recording isn't a priority. It is for those who are comfortable with event-based video clips and can mount the camera high enough to prevent theft. Buyers should be aware of potential durability and battery performance trade-offs, especially in wetter or less sunny environments.
