Anker’s eufy S4 video doorbell introduces 360-degree AI tracking and panoramic video. It features 3K recording, motion detection, and VR mode, with pre-orders open now. Shipments expected by October 2026.
Anker’s new eufy S4 video doorbell features 360-degree AI tracking and panoramic video capabilities, marking a significant upgrade in home security technology. The device, announced recently, is designed to provide comprehensive coverage of the doorstep, with advanced detection and recording features that do not rely on cloud storage. This development is notable for homeowners seeking more complete and intelligent surveillance options, especially with its VR integration and AI-powered auto-framing.
The eufy S4 utilizes a 180-by-180° lens that covers the entire front area from floor to ceiling and wall to wall. Its core feature, OmniTrack AI system, locks onto detected persons and automatically crops the panoramic view to keep them centered in a tighter shot. The camera records in 3K resolution (3072 x 3072 pixels) at up to 24 frames per second, with HDR support and up to 8x zoom. It includes dual spotlights for color night vision, enhancing visibility during low-light conditions.
Detection relies on a combination of hardware: radar sensors for long-range movement detection and PIR sensors near the door to distinguish people from false triggers like insects or rain. Users can draw custom detection zones within a 120° field extending up to eight meters. The device also features a welcome light that activates as visitors approach.
The S4 is powered through existing 16 to 24 VAC wiring, omitting battery or solar options, but it includes a 2600mAh battery backup for power outages. Storage is local, with 4GB of built-in storage for clips, eliminating the need for a cloud subscription. For extended recording and AI recognition capabilities—detecting people, vehicles, pets, and packages—users can add a HomeBase S380 hub. The device supports integration with Amazon Alexa, Apple Home, and Google Home, though full VR and AI features are limited to the eufy app and HomeBase setup.
The device is priced at $299.99 / £69.99, including a Chime 2, with pre-orders now open. Eufy expects to ship the S4 by the end of October 2026.
Implications of 360-Degree AI Tracking in Home Security
The eufy S4 represents a notable advancement in home security technology by combining panoramic video with AI-powered auto-tracking. Its ability to automatically lock onto and crop around detected individuals offers homeowners a more comprehensive and precise surveillance experience, reducing blind spots common with traditional doorbells. The device’s local storage and AI recognition features also enhance privacy and security, as data does not rely solely on cloud services.
Furthermore, the integration with popular smart home platforms and optional AI hub expands its compatibility and functionality, making it suitable for a broad range of users. The device’s pricing and pre-order availability suggest that it aims to compete in the growing market of advanced home security systems, especially those emphasizing AI and user control.
This development could influence other manufacturers to adopt similar panoramic and AI-tracking features, raising the standard for smart doorbells and home surveillance devices. For consumers, it offers a more intelligent and adaptable security solution, potentially reducing false alarms and increasing the likelihood of capturing critical footage.

Background on Eufy’s Security Innovations
Since its inception, eufy, a brand under Anker, has focused on providing affordable yet feature-rich home security products. Previous models offered HD video, local storage options, and integration with major smart home ecosystems. The company has steadily increased its focus on AI and advanced detection, introducing features like person detection and activity zones in earlier devices.
The new S4 builds upon these innovations by offering a panoramic lens and 360-degree tracking, addressing limitations faced by traditional rectangular cameras. The announcement comes amid a broader industry trend toward AI-enhanced surveillance, with competitors also exploring wide-angle lenses and intelligent tracking. The S4’s emphasis on local storage and privacy aligns with growing consumer demand for data security and control.
Prior to this, eufy’s flagship models primarily relied on cloud storage subscriptions for AI features, but the S4’s local storage option and optional AI hub mark a strategic shift to more flexible and privacy-conscious solutions.

Unanswered Questions About the S4’s Capabilities and Deployment
Details remain unclear regarding the full extent of AI accuracy in real-world conditions, especially in complex environments with multiple moving objects. It is not yet confirmed how well the auto-tracking performs during high traffic periods or in adverse weather conditions. Additionally, the integration with third-party platforms like Apple Home is limited to basic live view, and the full VR mode is only available within the eufy app, raising questions about cross-platform functionality.
It is also uncertain how the device’s local storage will handle longer periods of recording without cloud backup, and whether firmware updates will enhance AI detection over time. The shipping timeline, while targeted for late October 2026, could be subject to delays, as with many tech product launches.
