Revolutionary Triple-Lens Bullet-PTZ Camera: A single groundbreaking device that replaces and outperforms separate bullet and PTZ cameras. The upper 4K bullet lens delivers a 130° fixed wide view, while the lower 2K dual-lens PTZ offers 360° smart tracking and zoom.
Bullet-to-PTZ Tracking and Auto-Framing: Once the bullet cam detects a subject, the PTZ camera instantly locks on, tracks, and zooms in to capture details up to 164 ft away. When more subjects enter the frame, it automatically zooms out to ensure they all stay visible.
Powerful Solar-Charging with SolarPlus: Stay charged year-round with a 5.5W ultra-large solar panel and SolarPlus 2.0. Just 1 hour of direct sunlight a day keeps the camera running, and the detachable design makes setup easy and flexible.
Great on Its Own: eufyCam S4 can work independently—no HomeBase needed. It features on-device AI for smart human, vehicle, and pet detection. It comes with 32 GB built-in storage, expandable up to 256 GB via microSD (not included).
Better with HomeBase S380: Unlock BionicMind AI to differentiate family from strangers. With 16 GB built-in storage, expandable up to 16 TB, rest easy knowing your videos are stored securely. Use the latest eufy app and update HomeBase S380 to V3.7.2.8+ to enable 24/7 recording and Snapshots. Other HomeBases (S280/Mini/Professional) and eufy NVR are not supported.No subscription fee.
Precise Detection, Powerful Deterrence: Radar and PIR sensors deliver precise motion alerts with fewer false alarms. When a threat is detected within your set zone or schedule, red and blue warning lights and a 105 dB siren activate to deter intruders.
Customers find the security camera to be of superior quality with top-notch picture and video, and appreciate its ease of setup, particularly with wood mounting. The functionality and value for money receive mixed feedback – while some say it works well and is worth the money, others report inconsistent performance and consider it overpriced. The motion tracking and battery life also get mixed reviews, with some praising the tracking while others note hit-or-miss motion detection, and while some report consistent 100% battery charge, others mention quick battery drain. Wi-Fi connectivity is another area of concern, with customers reporting unreliable connections.
