Overview
The eufyCam 3 (S330) is eufy’s 4K solar outdoor camera, built around an integrated solar panel for year-round ‘Forever Power’ and face-recognition AI through HomeBase 3. With an f/1.4 aperture and 8MP sensor it captures sharp, bright footage day and night, all stored locally with no subscription.
Key Features
Setup & Compatibility
Set up in the eufy Security app on 2.4GHz Wi-Fi and pair to a HomeBase 3 with the SYNC button. The built-in solar panel keeps it charged with a couple of hours of daily sun. The motion sensor detects movement 8–10m away — mount so movement crosses the view.
What’s New
The integrated solar panel is the key feature — no separate panel or cable to mount, just sunlight keeping it topped up, paired with eufy’s 4K sensor and HomeBase 3 face recognition.

Is Eufy Safe? The Privacy History Explained
Eufy markets its cameras on privacy and local, subscription-free storage, but it’s worth knowing the background. In November 2022 a security researcher found that some eufy cameras uploaded thumbnail images to the cloud even when cloud features were switched off, and that camera streams could in some cases be viewed without authentication by anyone with the right link. In January 2023, eufy’s parent company Anker acknowledged to The Verge that its cameras were not natively end-to-end encrypted at that time.
In January 2025 the New York Attorney General secured a $450,000 settlement with the companies distributing eufy products over these security findings, requiring them to strengthen their security programme and encrypt video in storage and transit.
Since then eufy has moved its cameras to encrypted-by-default streaming, applied AES-128 and RSA-1024 encryption on HomeBase 3, run third-party security audits and launched a bug-bounty programme. If subscription-free local storage and strong privacy are the reason you’re looking at eufy, it’s sensible to keep firmware up to date and review your cloud and notification settings. We think the current products are a reasonable choice, but we’d rather you knew the full history and decided for yourself.
