Triple-Lens Bullet-PTZ Camera Kit

The eufyCam S4 2-Cam Kit combines a 4K bullet lens with a 2K dual-lens PTZ in each unit. The fixed upper lens covers a 130° view while the lower PTZ provides 360° tracking and zoom up to 164 ft. Designed for homeowners who want wide coverage and detailed follow-up without wiring.

Wireless Setup and Storage Requirements

Each camera operates wirelessly and includes a detachable 5.5W solar panel that needs roughly one hour of direct sunlight daily. The kit works standalone with 32GB internal storage per camera, expandable to 256GB via microSD. For 24/7 recording and BionicMind AI, a HomeBase S380 running firmware 3.7.2.8 or later is required; other HomeBase models and eufy NVR are not supported.

Replaces Separate Bullet and PTZ Cameras

A single S4 replaces the need to mount and align distinct bullet and PTZ devices, cutting installation time and reducing blind spots. The upgrade is worthwhile when you want automatic hand-off from wide-angle detection to close-up tracking with 8X zoom and colour night vision, all without monthly fees.

Should I choose the standalone cameras or add a HomeBase S380 for this S4 kit?

The S4 works alone with on-device AI and 32 GB storage; adding HomeBase S380 unlocks BionicMind AI, 16 TB expansion and 24/7 recording on firmware 3.7.2.8+.

What does the 164 ft tracking range mean when the bullet lens spots someone at night?

The 4K bullet lens detects motion across 130°, then the 2K PTZ zooms 8× to follow the subject up to 164 ft away with color night vision.
