| Anker is releasing a new video doorbell, the Eufy Video Doorbell S4. |
LAS VEGAS — Amid the flashing lights and futuristic promises of CES 2026, one of the most practical — and potentially transformative — reveals comes from a familiar name in the power and smart home space: Anker. Following a quiet preview at IFA 2025, the company is officially pulling back the curtain on the Eufy Video Doorbell S4, a device that aims to reinvent how we monitor our front doors.
In a market that has felt increasingly quiet, with iterative updates and similar designs, the S4 represents a notable step forward, primarily through its ambitious claim of a true 360-degree field of view.
Price, Availability, and What It Replaces
The Eufy Video Doorbell S4 is expected to hit the market in the first quarter of 2026, carrying a recommended retail price of $279.99. Anker has not yet provided a specific launch date, but CES attendees are getting their first live look at the finished product.
The new model effectively succeeds the popular Eufy Video Doorbell Dual, which launched roughly four years ago with a unique two-camera system. That design used one camera for head-on views and a second to look down at packages. The S4, however, aims to consolidate that functionality into a single, sophisticated lens.
One Lens to See It All: The 360-Degree Promise
The headline feature is what Anker is calling a 360-degree field of view, achieved through a lens with 180-degree horizontal and 180-degree vertical viewing angles. This "all-seeing" perspective is designed to cover the area directly in front of your door and the ground below it simultaneously—perfect for spotting delivered packages or seeing who’s standing at your step without blind spots.
This intelligent viewing is powered by AI Tracking 2.0. The system doesn’t just capture a wide area; it can identify a subject like a person’s face, automatically zoom in, and track their movement, ensuring they stay in frame and in focus.
For those ready to upgrade their home security, the Eufy Video Doorbell S4 is now available for pre-order on Amazon.
Crisp Imaging and Reliable Power
Video quality remains a crucial battleground, and the S4 enters the fray with an integrated 3K camera. Anker promises crystal-clear images even in low-light night conditions, thanks to a sensor suite combining dual PIR (Passive Infrared) for heat detection, radar for precise motion sensing, and AI-powered image processing algorithms.
Standard two-way audio with noise cancellation is included, allowing for clear conversations with visitors or delivery personnel.
Flexibility is another key focus. The doorbell is designed to accommodate nearly any home setup with triple power options: it can be hardwired to existing doorbell wiring for constant power, run on its integrated rechargeable battery, or be connected to an optional solar panel for a maintenance-free experience.
A Fresh Breath for the Smart Home
The smart doorbell segment has been due for a spark of innovation. By consolidating a dual-camera setup into a single, more intelligent 360-degree unit, Anker’s Eufy Video Doorbell S4 isn’t just an upgrade—it’s a rethinking of what a video doorbell should do. If it delivers on its CES promises, it could very well set a new standard for convenience and coverage, making our doorsteps smarter and more secure than ever before.
