Auto-tracking
Home security has evolved beyond static cameras that simply record what's directly in front of them. The eufyCam S4 represents a breakthrough approach: a sophisticated dual-camera system that combines comprehensive area monitoring with intelligent subject tracking, all powered entirely by the sun.
This isn't just another solar security camera. The S4's innovative design features two distinct camera systems working in perfect harmony – a fixed 4K wide-angle camera that never misses the big picture, and a responsive 2K Pan-Tilt-Zoom camera that automatically follows movement with remarkable precision.
The first solar security camera that thinks and moves like a professional security operator

Active Deterrence
105dB siren and red/blue warning lights activate automatically when threats are detected
INTELLIGENT TRACKING SYSTEM
Dual-Camera Coordination
The S4's breakthrough lies in how its two camera systems work together. The upper 4K camera maintains constant surveillance of your entire property with its 130° field of view, ensuring nothing escapes detection. When movement is spotted, the lower 2K PTZ camera springs into action, rotating a full 360° to lock onto the subject with remarkable precision.
This coordination creates an unprecedented level of security coverage. You get both the wide situational awareness of a fixed camera and the detailed tracking capabilities of a PTZ system, eliminating the blind spots that plague traditional single-camera setups.
SOLAR POWER INNOVATION
SolarPlus™ 2.0 Efficiency
The S4's solar system represents a significant leap forward in renewable security technology. The 5.5W ultra-large panel is designed to capture maximum energy even in challenging weather conditions, requiring just one hour of direct sunlight to power the camera for an entire day.
The detachable solar panel design offers exceptional installation flexibility, allowing you to position the camera in the optimal location for surveillance while placing the panel where it receives maximum sun exposure. This separation eliminates the compromise between security coverage and power generation that hampers other solar cameras.
