Eufy SoloCam S340 Camera Review: My Detailed Test
Par Robert Doudelain•September 9, 2025•4 min de lecture•Surveillance camera review
Presentation and Installation
The Eufy SoloCam S340 is a 100% wireless outdoor security camera with 3K resolution, a dual-lens system, 360° coverage, and solar power. Right out of the box, you can tell the product is well-finished, compact, and designed for quick installation.
Installation is indeed simple: a few screws, a QR code to scan via the Eufy Security app, and the camera is ready to use. The solar panel is detachable, allowing it to be oriented separately for optimal sunlight exposure.
Image Quality and 8x Zoom
With 3K resolution and a dual-lens system, this camera is impressive. The image is clear both day and night, with a very useful 8x digital zoom to identify details from a distance. Faces remain recognizable up to 15 meters.
The dual-view function allows simultaneous display of a wide-angle (panoramic) view and a zoomed-in view on a point of interest. This is convenient for monitoring a gate while keeping an eye on the street, for example.
360° Surveillance – SoloCam S340
Like other competing models, the camera can rotate horizontally to cover its entire environment without blind spots. In automatic mode, it follows detected movements. In manual mode, you can control the camera directly from the app. It’s smooth, responsive, and precise.
Battery Life and Solar Panel
The solar power works very well, as long as the panel is properly exposed. According to my tests, 2 to 3 hours of direct sunlight per day is enough to keep the battery above 90%, even with multiple daily detections.
The panel is removable, allowing for great flexibility in placement—especially if the wall where the camera is mounted isn’t optimally oriented.
Advanced Features
The SoloCam S340 is HomeBase 3 compatible, which enables secure local recording and integration into a multi-camera Eufy system. Without HomeBase, the camera can record locally (internal memory) but without external storage.
Two-way audio is included, clear and effective. The app allows you to receive alerts, view live footage, and configure activity zones.
Note: the camera operates exclusively on 2.4 GHz Wi-Fi. No 5 GHz support, which may be a limitation for some modern home networks.

Verdict

It combines 3K resolution, a smart dual-lens system, and 360° coverage, with fast installation and a genuinely functional solar-powered battery. Subscription-free and easy to integrate into an existing Eufy system, it’s an excellent choice for anyone seeking an efficient, autonomous security solution.
Rating: 9/10 – An excellent balance between performance, simplicity, and long-term savings.
