eufy S4 Triple-Lens PTZ Camera
The eufyCam S4 Triple-Lens PTZ Camera combines a 4K fixed bullet camera with a dual-lens 2K PTZ camera for wide-angle monitoring and detailed close-up tracking. Featuring 360° pan coverage, AI-powered auto-tracking, SolarPlus 2.0 charging, and built-in local storage, it provides flexible outdoor security with no mandatory monthly subscription.
Key Features
2-in-1 Triple-Lens Bullet and Pan-Tilt-Zoom Camera: The upper 4K wide-angle camera delivers a 130° fixed view of the entire area, while the lower 2K dual-lens Pan-Tilt-Zoom camera rotates 360° for all-around coverage.
Bullet-to-PTZ Tracking and Auto-Framing: When the bullet camera detects a person, the Pan-Tilt-Zoom camera locks on and auto-tracks them with a sharp, centred close-up from up to 50 metres. When other subjects enter the frame, it automatically zooms out to ensure they're all visible.
Year-Round Power with SolarPlus™ 2.0: Stay charged in any weather with a 5.5W ultra-large solar panel and SolarPlus™ 2.0. Just 1 hour of direct sunlight a day keeps the camera running, even on a cloudy day, and the detachable design makes setup easy and flexible.
Great on Its Own: eufyCam S4 delivers next-level smart security independently, even without a HomeBase. It features on-device AI for smart person, vehicle, and pet detection and comes with 32GB of built-in storage that's expandable up to 256GB with a microSD card (not included).
Better with HomeBase S380: Unlock BionicMind™ AI to instantly differentiate family from strangers. With 16GB of built-in storage that's expandable up to 16TB, rest easy knowing you can securely store hours of footage. Before setup, update your HomeBase S380 to version V3.7.2.8 or later and use the latest eufy app version; otherwise, eufyCam S4 won’t support 24/7 recording or Snapshot.
Accurate Detection, Powerful Deterrence: Radar and PIR sensors deliver accurate motion alerts for fewer false alarms. When a threat is detected within your set zone or schedule, red and blue warning lights and a 105 dB siren activate to deter intruders.
HomeBase 2 (HomeBase S280), HomeBase Mini, HomeBase Professional, and eufy NVR are not currently supported.
