eufyCam S4 2-Cam Kit 4K Solar Security Cameras with HomeBase 3 – E81723W1

eufyCam S4 2-Cam Kit (E81723W1) delivers advanced outdoor security with two triple-lens cameras and the included HomeBase 3 (S380).

Each camera combines a 4K fixed wide-angle lens with a dual-2K Pan-Tilt-Zoom (PTZ) system, allowing you to monitor a wide area and follow moving subjects in greater detail. Intelligent Bullet-to-PTZ tracking automatically switches from wide-area detection to close-up tracking, while auto-framing adjusts the view to keep subjects visible.

The SolarPlus 2.0 system includes a detachable 5.5W solar panel for each camera, providing flexible solar charging. Radar and PIR motion detection, color night vision, warning lights and a built-in siren offer additional security.

With HomeBase 3, enjoy BionicMind AI facial recognition and expandable local storage without mandatory monthly subscription fees.
