The S4 blends a 4K fixed bullet lens with a 2K dual-lens PTZ module so the system can monitor wide areas and then lock on to individuals for detail. The camera's built-in solar charging and on-device AI mean it can run independently for routine surveillance, while optional HomeBase S380 integration unlocks advanced cloud-style features for users who want longer retention and smarter identification.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTriple-lens design:\u003c\/strong\u003e Combines a 4K 130 fixed wide view with a 2K dual-lens PTZ so users get both broad coverage and close-up detail without extra cameras.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBullet-to-PTZ tracking:\u003c\/strong\u003e The system auto-locks and follows detected subjects, zooming in to capture identifying features up to about 164 ft away.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolarPlus charging:\u003c\/strong\u003e An ultra-large 5.5W detachable solar panel and SolarPlus 2.0 keep the camera running with as little as 1 hour of direct sunlight a day.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandalone operation:\u003c\/strong\u003e On-device AI provides human, vehicle, and pet detection with 32 GB internal storage, allowing the camera to work without a HomeBase.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHomeBase S380 compatibility:\u003c\/strong\u003e When paired with the S380 and updated firmware, users unlock BionicMind AI, 24\/7 recording, Snapshots, and large expandable storage options for extended retention.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive deterrence:\u003c\/strong\u003e Radar and PIR sensors reduce false alerts and trigger red\/blue warning lights plus a 105 dB siren to deter intruders.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe eufyCam S4 suits homeowners and small businesses that need flexible coverage from a single device: wide-area monitoring by day and precision zoom and tracking when motion is detected.
