Installation and App Experience
Setting up the S350 is a breeze through the eufy Security app. The dual cameras calibrate automatically, and within minutes you can customise detection zones, notifications, and viewing preferences. The app also allows you to control pan and tilt manually or set up automated patrol patterns — ideal for large spaces like open-plan living rooms or play areas.
Image Quality and Night Vision
Thanks to the dual-lens setup, the S350 captures both wide-area coverage and zoomed-in detail in stunning 4K UHD and 2K clarity. Low-light performance is exceptional, with infrared LEDs that preserve detail even in complete darkness. The zoom lens delivers crisp close-ups without pixelation, making it perfect for pet or baby monitoring.
AI Features and Smart Integration
The onboard AI is capable of identifying humans, pets, and sound-based triggers like baby cries. It supports motion tracking that locks onto subjects and follows them smoothly using the pan & tilt motors. Integration with Alexa and Google Assistant allows voice commands and smart display streaming. It also supports Apple HomeKit Secure Video for iOS users, providing end-to-end encrypted storage via iCloud.
Storage and Privacy
The S350 stores footage locally via a microSD card, so there are no ongoing fees. For cloud storage, users can optionally subscribe to eufy’s cloud plan, but it’s entirely optional. The camera includes privacy mode, where the lens physically turns inward when disabled — a reassuring feature for any indoor device.
Final Verdict
The eufy S350 Indoor Cam stands out in a crowded market with dual lenses, true 4K video, and AI-powered tracking that’s accurate and responsive. It’s ideal for anyone looking to upgrade their indoor surveillance system with top-tier clarity and zero monthly fees. Whether for family safety or home monitoring, it’s one of the best indoor cameras you can buy in the UK for 2025.
