Overview
The eufy Security SoloCam S340 is an advanced outdoor smart security camera that brings together dual-camera 3K resolution, 360° field of view, and solar-powered autonomy. Built for homeowners who want intelligent surveillance without monthly fees or complicated installations, this wire-free system supports both Google Assistant and Amazon Alexa. In this in-depth review, we examine the SoloCam S340’s real-world performance, smart features, security potential, and whether it’s the right fit for UK homes in 2025.
Design and Installation
The camera sports a clean black-and-white design that’s both discreet and modern, blending in well with a variety of outdoor walls. Its build quality feels solid despite the plastic construction, and the compact 8.7 x 8.7 x 12 cm size allows for easy placement.
Installation is genuinely DIY-friendly—wall mounting takes less than five minutes using standard screws. Once secured, the removable solar panel can be positioned for optimal sunlight exposure. There’s no wiring required, and it pairs quickly to your phone over 2.4 GHz Wi-Fi.
3K Dual-Camera Clarity with Zoom
One of the standout features of the SoloCam S340 is its dual-lens setup. It combines a wide-angle lens for full-area coverage with a telephoto lens capable of up to 8× zoom. This allows simultaneous viewing of the big picture and detailed close-ups in one frame.
With 3K video capture at 15 FPS, the footage is impressively sharp both day and night. You can clearly identify faces, license plates, or package details at distances up to 50 feet. It also features advanced night vision up to 10 metres, thanks to integrated infrared and LED sensors.
360° Coverage and No Blind Spots
The motorized pan and tilt mechanism gives you true 360° horizontal coverage. Using the app, you can remotely adjust the angle in real time—monitor your driveway, garden, side entrance, or patio with a single camera.
This makes the S340 a strong alternative to multi-camera setups. The motion tracking system intelligently follows movement across the frame, giving peace of mind that no activity goes unnoticed.
Smart Features and Mobile App
The companion eufy Security app (iOS and Android) offers full control: live view, motion alerts, pan/tilt control, and dual-view mode. You can customize motion zones, set schedules, and review event clips stored locally.
Integration with Amazon Alexa and Google Assistant allows you to view the feed on compatible smart displays. You don’t need a subscription—video is stored on-device or on the optional HomeBase S380 for added AI features like facial recognition and Smart Detection Zones.
Battery and Solar Panel Performance
The built-in rechargeable lithium-ion battery is designed for all-season endurance. Under regular UK weather conditions, the detachable solar panel provides enough power for year-round operation—assuming at least 2 hours of direct sunlight per day.
Battery warnings appear in the app, and you can charge via USB-C if solar input is insufficient. The overall energy efficiency and 9W power draw make it sustainable and eco-friendly for modern homes.
Weatherproof Build and Durability
With an IP65 waterproof rating, the S340 can handle British rain, fog, and temperature swings. The sealed housing prevents dust and moisture ingress, and the solar panel is also weather-rated for outdoor mounting.
Unlike some budget cameras that suffer from condensation or image fogging, the SoloCam S340 stays clear and consistent even after heavy downpours.
Security and Privacy Protections
Data is secured with military-grade AES-128 encryption. Video is stored locally on the camera or through the S380 HomeBase—there’s no requirement to upload footage to the cloud unless you choose to. This gives users full control over their privacy.
The device supports two-way audio, tamper alerts, and can trigger a siren if suspicious movement is detected. It’s a smart choice for households focused on privacy, autonomy, and advanced detection.

How It Compares
Compared to similar smart outdoor cameras like the Arlo Pro 5S or Ring Spotlight Cam Pro, the SoloCam S340 stands out with its dual-lens design, full 360° rotation, and included solar panel—all without mandatory cloud subscriptions. If you want a powerful, subscription-free, intelligent outdoor camera with complete coverage, the S340 offers excellent value in its class.
Final Verdict
The eufy Security SoloCam S340 is a premium wireless outdoor camera that delivers on clarity, power autonomy, and smart control. Its dual-lens zoom, wide-angle coverage, and privacy-first design make it an ideal option for UK homeowners who want full surveillance without hidden costs.
