Anker’s latest innovation in home security, the eufy Video Doorbell S4, is poised to redefine the way homeowners interact with visitors at their doorstep. Moving beyond the conventional rectangular field of view, the S4 boasts a groundbreaking 180-by-180-degree panoramic lens, offering an unprecedented floor-to-ceiling and wall-to-wall perspective. This expansive coverage aims to eliminate blind spots and provide a comprehensive view of the entire doorstep area, a significant upgrade from the narrower frames typical of most video doorbells currently on the market.
The revolutionary panoramic feed is further enhanced by an intuitive control system. Users can pan across the expansive visual landscape by simply moving their smartphone or, for an even more immersive experience, a VR headset. This integration transforms the doorbell notification into an interactive event. When a visitor rings the doorbell, it initiates an incoming video call, automatically opening the panoramic feed in full-screen VR mode. This feature, which eufy proudly bills as a world-first for a doorbell, includes robust two-way audio, allowing for seamless communication with guests regardless of their location on the property.
The technological prowess of the eufy Video Doorbell S4 extends beyond its immersive viewing capabilities. At its core lies the sophisticated OmniTrack AI system, designed to intelligently track and focus on individuals once they enter the camera’s field of view. This advanced AI automatically frames and crops the panoramic image, ensuring the detected person remains centered in a tighter, more detailed shot for each event. This auto-framing feature is crucial in maintaining clarity and identifying individuals, preventing them from becoming distant, indistinct figures within the wider panorama.
The camera itself is engineered for superior image quality, capturing video in a sharp 3K resolution. It records in a square 9MP frame (3072 x 3072 pixels) at a fluid up to 24 frames per second, incorporating High Dynamic Range (HDR) technology for enhanced detail in both bright and shadowed areas. For closer inspection, the S4 offers up to 8x zoom, allowing users to scrutinize details from a distance. Furthermore, its dual spotlights provide powerful color night vision, ensuring clear visibility and identification of visitors even in complete darkness, a critical feature for round-the-clock security.
Beyond its visual capabilities, the S4 employs a multi-layered detection system to ensure accurate alerts. It leverages radar technology for long-range movement detection, complementing the two integrated PIR (Passive Infrared) sensors positioned closer to the door. This combined approach, according to eufy, is designed to intelligently differentiate between genuine human presence and false triggers such as insects or adverse weather conditions like rain. This advanced detection system feeds into customizable detection zones, allowing users to draw specific areas within the doorbell’s 120-degree field of view, extending up to eight meters. The system is capable of identifying people, general motion, packages, and even faces, further enhancing the utility and intelligence of the device. As a welcoming gesture, a subtle welcome light illuminates as visitors approach, adding a touch of hospitality to the security features.
A significant practical advantage of the eufy Video Doorbell S4 is its power source. It exclusively utilizes existing 16 to 24 VAC doorbell wiring for its power needs, eliminating the reliance on batteries or solar panels. This direct wired power ensures consistent operation without the concern of battery depletion or the limitations of solar charging, especially during periods of low sunlight. While it does not feature a battery for primary power, it does include a 2600mAh battery that serves as a crucial backup during temporary power outages, ensuring continuous functionality even when the mains power is interrupted.
In terms of data storage, eufy is continuing its commitment to user privacy and cost-effectiveness by foregoing mandatory cloud subscriptions. The S4 comes equipped with 4GB of built-in local storage, sufficient for storing event-triggered clips. For users requiring more robust storage solutions, Anker offers the HomeBase S380. This optional hub significantly expands the doorbell’s capabilities, unlocking continuous 24/7 recording and enabling advanced AI recognition features for people, vehicles, pets, and packages. The HomeBase S380 is positioned as the central control unit for eufy’s Edge 5.0 range, which comprises up to five connected devices. Frank Zhu, General Manager at Anker eufy, highlighted the company’s vision, stating that homeowners increasingly view their property as "one cohesive space they need to protect," underscoring the importance of integrated and comprehensive security solutions.
Platform compatibility is another key aspect of the S4’s integration into the smart home ecosystem. Beyond the dedicated eufy app, the doorbell works seamlessly with major smart home platforms including Amazon Alexa, Apple Home, and Google Home. However, it’s important to note that full functionality, particularly the VR mode and OmniTrack AI features, is exclusive to the eufy app. Integration with Apple Home, for instance, necessitates the presence of the HomeBase S380. While the third-party platforms provide access to a fixed live view, they do not replicate the immersive VR experience or the intelligent tracking capabilities.
Anker has set the retail price for the eufy Video Doorbell S4 at $299.99 in the United States and £69.99 in the United Kingdom, with a Chime 2 unit included in the package. Pre-orders are currently open, and eufy anticipates that shipments will commence by the end of October 2026, indicating a strategic product launch and manufacturing timeline.
