eufy Security eufyCam S4 Solar Triple-Lens Bullet‑PTZ Camera — 4K UHD + 2K PTZ, 360° Pan/Tilt, 8× Hybrid Zoom, Auto-Track, Color Night Vision, HomeBase S380 Compatible

A single camera that replaces both bullet and PTZ units: the eufyCam S4 pairs an upper 4K bullet lens with a 130° fixed wide view and a lower 2K dual-lens PTZ module capable of 360° smart tracking and zoom. When the wide bullet lens spots a subject, the PTZ instantly locks on, auto-frames and zooms in to reveal details out to 164 ft; if additional people appear, it will automatically zoom out so everyone stays in view. Solar-powered with SolarPlus 2.0: the 5.5W ultra-large solar panel keeps the system running year-round — just 1 hour of direct sunlight a day is enough — and its detachable design simplifies installation. Operates standalone or with HomeBase S380: eufyCam S4 can run independently using on-device AI for human, vehicle, and pet detection and includes 32 GB built-in storage, expandable up to 256 GB via microSD (not included). Pairing with HomeBase S380 unlocks BionicMind AI for distinguishing family from strangers and provides 16 GB built-in storage expandable up to 16 TB. If you already own a HomeBase S380, make sure it’s updated to version V3.7.3or later and that your eufy app is updated to the latest version to enable 24/7 recording and Snapshot features. Precise sensing and strong deterrents: radar and PIR sensors reduce false alerts while delivering accurate motion notifications. When motion is detected inside your configured zone or schedule, red and blue warning lights plus a 105 dB siren activate to help deter intruders. Additional capabilities include color night vision, auto-tracking, and 8× hybrid zoom for close-up clarity.
