Triple-Lens Bullet-PTZ Camera

The eufyCam S4 combines a 4K bullet lens with a 2K dual-lens PTZ unit in one wireless outdoor camera. It is built for homeowners who want wide-area awareness and close-up detail without installing multiple devices. On-device AI detects people, vehicles and pets locally with no monthly fee.

Sustained Solar Operation

A 5.5 W SolarPlus 2.0 panel keeps the battery charged with only one hour of direct sunlight per day. Radar and PIR sensors reduce false alerts so the PTZ activates only when genuine motion occurs, preserving power during long recording periods. The detachable panel allows flexible placement for consistent exposure.

Replaces Separate Bullet and PTZ Units

This single camera covers the roles of a fixed wide-angle bullet cam and a motorised tracking PTZ, saving mounting points and cabling. The jump is worth it when you need 130° overview plus 360° tracking with 8× zoom up to 164 ft. It works standalone with 32 GB internal storage or expands to 256 GB via microSD; pairing with HomeBase S380 adds BionicMind AI and up to 16 TB capacity.
