Eufy eufyCam S330 (eufyCam 3) Add-on Camera

4K Security That Charges Itself — 365-Day Battery Meets Built-In Solar

The eufyCam S330 (eufyCam 3) add-on camera captures outdoor footage in true 4K Ultra HD (3840 × 2160), making faces, license plates, and activity crisp enough to actually identify. Infrared and color night vision keep the picture clear after dark, and a motion-activated spotlight adds full-color detail exactly when something moves.

Power is where the S330 shines: a rechargeable lithium battery delivers up to 365 days per charge, and the integrated solar panel tops it up continuously with daily sunlight — a genuinely set-and-forget setup. Smart AI with self-learning human recognition distinguishes people, vehicles, and pets to cut false alerts, while two-way audio and a 100dB siren let you respond to whatever it sees.

Storage is local and subscription-free: 16GB built in, expandable up to 16TB via HDD or SSD through the HomeBase. The IP67-rated body handles rain, dust, and -20°C to 50°C extremes. Note: this add-on camera requires a eufy HomeBase 3 (S380).
