Our take on the eufyCam S330 (eufyCam 3) 4-Cam Kit

The eufyCam S330 kit pairs four wireless 4K cameras with the HomeBase 3 hub. Each camera runs on a rechargeable battery rated for months of use and carries an IP67 weather rating for outdoor mounting. The HomeBase 3 stores footage locally with encryption and expands over time, so there are no mandatory cloud fees. Its built-in AI sorts people, pets and vehicles, and the cameras add a spotlight for color night video. Reviewers rate it highly for sharp video and easy setup; the main complaints are slow app alerts and the cost of adding more cameras later.

About the eufyCam S330 (eufyCam 3) 4-Cam Kit

The eufyCam S330 (eufyCam 3) 4-Cam Kit includes four wireless 4K security cameras and the HomeBase 3. The cameras record at 4K (3840x2160) with infrared and color night vision. They are weatherproof with an IP67 rating, and each has a built-in motion-activated spotlight and a 100dB siren.

Each camera runs on a rechargeable lithium battery with an integrated solar panel. The battery lasts 365 days on its basic setting, and the solar panel extends that to continuous power. The cameras connect over 2.4GHz Wi-Fi and mount with screws, so no wiring is needed.

AI detection recognizes humans, vehicles and pets. Human recognition uses a self-learning algorithm. The HomeBase 3 manages the system and stores footage locally, with 16GB built in for about 3 months of use. Storage can be expanded with an HDD or SSD up to 16TB. The system has two-way audio and works with Alexa and Google Voice Assistant.
