Eufy unveils S4 camera with 4K fixed lens and dual 2K PTZ head

At the IFA trade show in Berlin on Wednesday, Eufy unveiled the eufyCam S4, a new outdoor security camera that pairs a fixed 4K wide angle lens with a dual 2K pan, tilt and zoom module and a detachable solar panel to deliver continuous, AI-driven surveillance for residential properties.

The S4 merges a stationary 4K bullet camera with a two‑lens PTZ head to provide both broad coverage and zoomed detail, Eufy said. The fixed lens offers roughly a 130 degree field of view while the PTZ unit delivers 360 degree tracking and can zoom in on subjects up to about 50 meters, or 164 feet, away. Eufy said the system uses a combined triple-lens array with roughly 16 megapixels of imaging and can autoframe and dynamically zoom out to keep groups in view.

Eufy emphasized detection and nuisance-alert reduction. The camera uses radar and passive infrared sensors to distinguish humans, vehicles and pets, and the company said those sensors feed on-device AI to minimize false alarms. When the fixed camera detects activity, the PTZ head locks on and follows the target until it leaves the scene. Built-in deterrents include four LED spotlights for color night vision, red and blue warning lights and...
