eufyCam S4 — 4K main + twin 2K PTZs, detachable solar panel & local AI

Eufy has unveiled the eufyCam S4, a multi-lens outdoor security camera system announced at IFA. The system combines a fixed 4K bullet camera with two 2K pan-tilt-zoom (PTZ) sensors that engage when movement is detected and automatically track subjects.

Key features

• 4K fixed bullet camera (130° field of view) with pan, tilt and zoom framing capabilities.
• Two 2K PTZ sensors providing 360° tracking and auto-framing up to ~164 ft (50 m) for people; intelligent zooming keeps groups in view.
• Dual motion detection using radar + passive infrared (PIR) to reduce false alarms (distinguishes humans vs vehicles).
• Warning lights (red/blue) and built-in siren to deter intruders on detection.
• Detachable 5.5 W solar panel that can fully charge the camera with ~1 hour of direct sunlight; rechargeable battery included.
• Optional HomeBase S380 hub adds BionicMind AI features: 99.9% accurate facial recognition (Eufy claim), cross-camera tracking and local storage up to 16 TB.
