The Next Generation of Home Surveillance: eufyCam S4 Launches as the Ultimate Solar-Powered Tri-Cam Security System

eufy, a global leader in home security technology and smart appliances by Anker Innovations, has once again raised the bar for DIY home protection with the launch of the eufyCam S4. Heralded as the industry’s first solar-powered hybrid camera that fuses a fixed bullet lens with dual pan-tilt-zoom (PTZ) lenses, the S4 introduces a revolutionary Tri-Cam design to the everyday homeowner. This single, compact device is engineered to deliver 360° AI tracking and meticulous detail, combining broad coverage with precision close-ups for truly non-stop security.

For years, homeowners had to choose between the wide, dependable coverage of a fixed camera and the detailed, dynamic tracking of a PTZ unit. eufy has eliminated that compromise. While the company previously demonstrated this advanced concept with the eufy PoE NVR Security System S4 Max—which utilized the Local AI Agent for network-wide intelligence—the eufyCam S4 now brings that same powerful, multi-angle protection into an accessible, battery-powered system. The result is a smarter, more versatile security solution that is set to replace and outperform separate security cameras across the home.

The Triple-Lens Revolution: From Fixed View to 360° AI Tracking

The ingenuity of the eufyCam S4 lies in its triple-lens configuration. It seamlessly integrates a 4K fixed bullet lens with a dual 2K PTZ camera in one unit. The 4K bullet lens provides a reliable 130° fixed field of view, maintaining a constant watch over crucial areas like main doors, pathways, and driveways. Simultaneously, the dual 2K PTZ camera provides 360° field-of-view tracking, perfect for actively monitoring large, dynamic spaces such as yards and gardens.

This powerful combination is driven by AI Tracking 2.0. The two camera systems work in sophisticated concert, automatically coordinating and reframing as activity moves across their zones. With Intelligent Auto-Framing, the PTZ lenses swiftly lock onto motion, automatically zooming in or out with incredible precision. This allows the camera to smoothly track people or objects up to an astonishing 50 meters (164 ft.) away, capturing detailed facial recognition from up to 15 meters. The triple-lens innovation ensures versatile coverage, eliminating the all-too-common security blind spots and capturing every event with high-definition clarity.

Uninterrupted Power: The Detachable Solar Advantage

Non-stop performance is the bedrock of reliable home security, and the eufyCam S4 is built to sustain it. Featuring eufy’s largest and most efficient solar panel to date, the camera is equipped with a powerful built-in 5.5W detachable solar panel. Under optimal conditions, just one hour of direct sunlight can fully charge the camera to power it for an entire day, providing robust, non-stop surveillance without the hassle of periodic charging.

The innovative detachable design allows for flexible installation. Homeowners can position the panel for maximum sun exposure, even if the camera itself is in a shaded spot, ensuring power efficiency regardless of the mounting location. Alternatively, it can remain attached for a cleaner, low-drill setup. To guarantee longevity and reliability in harsh outdoor environments, the solar panel features a unique edge-sealed design that prevents warping and bubbling. Furthermore, the use of ethylene tetrafluoroethylene (ETFE) film offers superior resistance to water, dust, and corrosion. Coupled with a quick-swap rechargeable battery, the S4 guarantees it stays powered in even the most extreme weather.

Advanced Intelligence and Deterrence Systems

The S4 is not just about passive monitoring; it's about active security and intelligent identification. The camera employs a Dual Detection System, leveraging both radar and Passive Infrared (PIR) technology. This highly accurate combination can reliably identify human and vehicle movement while filtering out ambient activity, drastically minimising the nuisance of false alerts that often plague simpler systems.

Security is further enhanced by powerful visual and auditory deterrence capabilities. When the system identifies an approaching intruder, the eufyCam S4 instantly activates red and blue warning lights alongside a thunderous 105dB siren. This robust, multi-sensory response delivers a powerful visual and auditory deterrent, often stopping unwanted activity before it can escalate.

Smarter Security with HomeBase AI Integration

While the camera excels at the frontier, its true intelligence is unlocked when paired with the HomeBase S380. The eufyCam S4 becomes part of an intelligent ecosystem where the camera focuses on capturing critical details, while the HomeBase, powered by advanced BionicMind™ AI, handles the heavy-lifting of processing. This is all handled locally, ensuring user data privacy and security remain paramount while facilitating advanced functions like facial recognition and precise identification of people, vehicles, and pets.

The system intelligence extends to user experience with features like Cross-cam Tracking, which automatically links related footage from multiple cameras into one continuous event timeline for seamless viewing. Furthermore, 24/7 Snapshots allows users to visually monitor their property around the clock without draining the battery with continuous recording, combining always-on awareness with the S4’s long-lasting, solar-powered performance.

Pricing and Availability

The eufyCam S4 is scheduled for retail launch on November 3rd, 2025, offering various options to suit different home sizes and security needs:

• Solo Camera: £249

• 2-Cam Kit with HomeBase S380: £549

• 4-Cam Kit with HomeBase S380: £949 (Exclusive to eufy.com/uk)
