eufyCam S4 - 4K Triple-Lens Outdoor Security Camera

The eufyCam S4 is designed to deliver advanced home security through a powerful 4K triple-lens surveillance system. A combination of a fixed ultra-wide 130° bullet camera and a pan-tilt-zoom (PTZ) camera with 360° coverage ensures that both broad areas and fine details are continuously monitored. Real-time smart auto-tracking is enabled when motion is detected, allowing subjects to be followed seamlessly across multiple camera views. A side-by-side live feed is provided through the app for complete situational awareness.

Enhanced AI-based monitoring is supported through intelligent detection of people, vehicles, and pets, while auto-framing ensures that individuals remain clearly captured even at long distances of up to 50 meters. The system is supported by solar charging technology and high-efficiency power management, allowing continuous operation even in low-light or partially shaded environments. Integration with smart home ecosystems further enhances usability, while optional 24/7 recording provides uninterrupted surveillance when a wired power connection is applied.
