Revolutionary Triple-Lens PTZ Technology
Why settle for blind spots? The eufyCam S4 features a groundbreaking dual-camera system. The fixed upper 4K lens maintains a wide-angle 130° view, while the lower 2K PTZ lens actively tracks motion. Using advanced AI-driven auto-framing, the camera identifies subjects and zooms in to capture facial details up to 164 feet away. When multiple subjects enter your property, the system automatically adjusts the zoom level to keep everyone in frame.
Intelligent auto-tracking ensures no detail is missed, even at 164 feet.

Forget the hassle of constant charging. Equipped with a massive 5.5W solar panel and SolarPlus 2.0 technology, the S4 requires just one hour of direct sunlight per day to maintain its charge year-round. The detachable solar panel design offers maximum flexibility for mounting, making it the perfect choice for remote locations or hard-to-reach areas.
