eufy Security eufyCam S4 2-Cam Kit — Solar Wireless Outdoor Triple‑Lens Bullet‑PTZ, 4K Bullet + 2K 360° PTZ, Auto Track, 8× Hybrid Zoom, Color Night Vision, Expandable Storage

All-in-one triple‑lens design replaces separate bullet and PTZ units: the upper 4K bullet lens gives a 130° fixed wide view, while the lower 2K dual‑lens PTZ module provides 360° smart tracking and zoom. When the bullet detects motion the system instantly hands off to the PTZ to lock on, auto‑frame and follow subjects — zooming in for detail up to 164 ft and zooming back out as additional people enter the scene. SolarPlus 2.0 and long‑run power: an ultra‑large 5.5W solar panel keeps the cameras charged year‑round. Just 1 hour of direct sunlight per day is sufficient to maintain operation, and the panel’s detachable design simplifies installation and placement. Storage and smart detection: pair with HomeBase S380 to enable BionicMind AI for distinguishing family from strangers. Each kit includes 16 GB built‑in storage and supports expansion up to 16 TB for long‑term video retention. Note: before setup, update your HomeBase S380 to V3.7.3 or later and install the latest eufy app — without these updates the eufyCam S4 will not support 24/7 recording or Snapshot. Reliable alerts and active deterrence: combined Radar and PIR sensors reduce false alarms while improving detection accuracy. When an intruder is detected in a configured zone or schedule, the system activates red and blue warning lights and a 105 dB siren to deter unwanted activity. Additional highlights: 8× hybrid zoom, auto‑tracking PTZ, and color night vision deliver clear, actionable footage for outdoor security.
