CES has always been a launchpad for the next big thing in smart home tech, and CES 2026 is no exception. This week, Anker’s smart home brand, eufy, is officially pulling back the curtain on a compelling new addition designed to make outdoor security both smarter and more sustainable. Introducing the eufy Solar Wall Light Cam S4—a sleek, all-in-one device that aims to replace your standard outdoor light with a powerful, self-sufficient security sentinel.
Blending a high-resolution camera with radiant outdoor lighting and impressive solar charging, the S4 is the latest model in the growing eufyCam S4 family. It promises to deliver comprehensive monitoring without the hassle of frequent battery changes or complex wiring.
A Clear View in 4K, Day or Night
At its core, the Light Cam S4 is built to see everything. It’s equipped with a 4K (3840 x 2160 pixel) camera featuring a wide f/1.6 aperture to capture detailed footage even in lower light conditions. But it’s not just about recording video after something happens; it’s about proactive detection.
The integrated radar sensor and AI-powered analytics work in tandem to detect motion from humans, vehicles, and pets—and can intelligently distinguish between them. Homeowners can fine-tune their security by customizing detection zones, range, and schedules directly from their phone. When the system detects something amiss, you’ll get a smart alert, and the device can actively deter intruders with a flashing light and a piercing 120 dB alarm.
More Than Just a Security Camera
What sets this model apart is its dual identity. It’s a fully functional outdoor light with a built-in RGBWW LED that can produce everything from warm white light (2,700K) for ambiance to bright daylight (6,500K) for security. It also offers a spectrum of colors, with presets that seem tailored for holidays—think spooky Halloween hues or festive Christmas colors.
Powering this feature set is a clever detachable 2W solar panel. Anker claims that just three hours of sunlight can generate enough power for a full 24 hours of operation, making it incredibly efficient. For extended cloudy periods, the integrated 10,000 mAh battery acts as a robust backup, storing enough juice for up to 40 days of use. This focus on solar efficiency addresses one of the biggest pain points for wireless outdoor devices: constant charging.
On the connectivity front, the S4 includes two-way audio for communicating with visitors or deterring trespassers, and it stores footage locally on 32 GB of embedded eMMC storage. For those invested in the Apple ecosystem, the device is compatible with Apple HomeKit when paired with a eufy HomeBase, allowing for seamless integration with other smart home routines and devices.
The launch of the S4 light follows the growing presence of the eufyCam line in global markets. For instance, the eufyCam S4 with 360-degree tracking has recently become available in Europe, expanding the brand’s reach. You can read more about that rollout here.
Pricing and Availability
Anker plans to bring the eufy Solar Wall Light Cam S4 to market with an attractive price tag. It’s expected to retail for $199.99 in the United States, positioning it as a competitive option in the smart security space. The current release window is set for by the end of March 2026. While US availability is confirmed, details on a launch in other markets, such as Europe, have not yet been announced.
For those ready to upgrade their home security and lighting with a single, solar-powered device, the eufy Solar Wall Light Cam S4 is shaping up to be a compelling option from a trusted brand. It will be available for purchase at major retailers like Amazon upon release.
As smart homes continue to evolve, products like this that combine multiple functions with true energy independence point the way forward. The eufy Solar Wall Light Cam S4 isn’t just watching your home; it’s lighting the path to a more convenient and secure future.
