Triple-Lens Bullet-PTZ Kit

The eufyCam S4 4-Cam Kit with Video Doorbell E340 delivers whole-home coverage using wireless cameras that combine a 4K bullet lens with a dual-lens PTZ unit. Each camera provides a 130° fixed wide view alongside 360° smart tracking and 8X zoom. On-device AI handles human, vehicle and pet detection without a subscription fee. The kit suits homeowners who want comprehensive outdoor monitoring with local recording and solar charging.

Solar Power and Local Storage

A 5.5W SolarPlus 2.0 panel keeps each camera running year-round with just one hour of direct sunlight daily. The detachable panel design allows flexible placement for optimal exposure. Every camera includes 32GB built-in storage expandable to 256GB via microSD for standalone operation. Pairing with HomeBase S380 unlocks BionicMind AI for familiar-face recognition and expands total capacity to 16TB. Radar and PIR sensors reduce false alerts while a 105 dB siren with red and blue lights provides active deterrence.

Replaces Separate Bullet and PTZ Units

This system replaces the need to install separate fixed bullet cameras and motorised PTZ units at each corner of a property. The bullet-to-PTZ tracking hands off subjects automatically, capturing details up to 164 ft away and auto-framing multiple people. The jump is worth it when you want 24/7 recording with snapshots, cross-camera tracking and centralised AI management via HomeBase S380 firmware 3.7.2.8 or later. It is not for buyers who need wired PoE connectivity or who rely on older HomeBase models that are not supported.
