Anker has announced the wired Eufy Video Doorbell S4, which combines a 180-by-180-degree panoramic lens with AI person tracking and 3K recording. It has 4GB of built-in clip storage, with continuous recording and additional recognition features available through a HomeBase S380. Pre-orders are open, and Eufy expects shipments by the end of October 2026.
Anker has opened pre-orders for the Eufy Video Doorbell S4, a wired smart doorbell with a 180-by-180-degree panoramic view, AI-powered subject tracking and 3K video recording. The company says the camera can follow a person across its wide image and reframe them in a closer shot; shipments are expected by the end of October 2026.
The S4’s lens is designed to show the doorstep from floor to ceiling and wall to wall. Owners can pan around the panoramic feed by moving a phone or VR headset. Eufy describes the product as a VR doorbell: a ring opens the feed in a full-screen VR mode, with two-way audio. These VR functions are presented as part of the Eufy app experience, not as features available through third-party smart-home platforms.
Eufy’s OmniTrack AI is designed to lock onto a person in view, while automatic framing crops the wider image to keep that subject centred. The camera records a square 9-megapixel, 3072-by-3072 image at up to 24 frames per second, with HDR and up to 8x zoom. Dual spotlights support colour night vision. These are manufacturer-stated specifications; independent testing results are not included in the announcement material.
For detection, the device combines radar and two PIR sensors, which Eufy says help distinguish people from triggers such as rain and insects. Owners can set detection zones within a 120-degree field, at distances of up to eight metres. The doorbell is listed as detecting people, general motion, packages and faces, and includes a welcome light that activates as visitors approach.
How the S4 Changes Doorstep Monitoring
The S4’s main selling point is the combination of a very wide image and automatic tracking. A conventional fixed frame can leave visitors near the edge or show too much surrounding space; Eufy says the S4 can let owners inspect the panorama manually and then keep a tracked person centred. That may make it easier to see activity across a porch, though the practical benefit will depend on installation position, lighting and how reliably tracking works in everyday conditions.
Its power and storage choices also shape who the product suits. The S4 requires existing wired doorbell power, so it is not a direct fit for homes without compatible wiring. It records clips to 4GB of built-in storage without a cloud subscription, while a separate HomeBase S380 adds continuous recording and more recognition categories. Buyers therefore need to distinguish the doorbell’s included features from functions that depend on buying the hub.
The listed prices are unusual: Anker’s supplied material gives $299.99 and £69.99, with a Chime 2 included. The large difference between those regional prices makes it worth checking the local listing and final price before ordering. The announcement does not explain the pricing discrepancy.

Wired Power, Storage and Smart-Home Support
The S4 is a wired-only doorbell, designed to run from existing 16-to-24-volt AC doorbell wiring. It has a 2,600mAh battery described as backup power during outages, but Anker is not offering the model as a battery- or solar-powered device. Installation suitability will depend on a home’s existing wiring and setup.
Basic clip storage is provided by 4GB of onboard memory, and Eufy says a cloud subscription is not required for that storage. Adding the HomeBase S380 enables continuous 24/7 recording and AI recognition for people, vehicles, pets and packages. The S380 is also described as the hub at the centre of Eufy’s five-device Edge 5.0 range, although the supplied material does not detail the other devices.
The doorbell also supports Amazon Alexa, Apple Home and Google Home. Apple Home integration requires a HomeBase S380. Eufy says these platforms provide a fixed live view, rather than the app’s VR mode or OmniTrack tracking, so compatibility does not mean every headline feature works outside the Eufy app.
““the world’s first VR doorbell””
— Anker Eufy, in its product description
Performance and Pricing Still Need Clarity
The announcement describes the S4’s tracking, detection and night-vision capabilities, but the supplied material does not include independent tests showing how accurately they work, how often false alerts occur, or how the system performs in different weather and lighting. It also does not specify how long clips remain in the built-in storage before older footage is overwritten, or provide details on video encryption and retention controls.
The listed US and UK prices differ sharply, and no explanation is provided. The source material also does not give a specific calendar date for shipping beyond the end-of-October 2026 estimate, or say whether delivery timing will vary by country. Buyers should verify current price, availability, wiring requirements and included features with Eufy or the retailer before placing an order.
Pre-Orders and October Shipments
Pre-orders are open, and Eufy expects to begin shipping the S4 by the end of October 2026. The next useful details for buyers will be region-specific availability, final local pricing and confirmation of delivery schedules. Reviews and hands-on testing may also clarify how the panoramic view and AI tracking perform outside the company’s product claims.
Key Questions
What is the Eufy Video Doorbell S4?
It is a wired video doorbell from Anker’s Eufy brand, with a 180-by-180-degree panoramic lens, AI person tracking and square 3K recording. It also supports two-way audio and app-based VR viewing.
Does the S4 need a subscription?
Eufy says clips can be stored on the doorbell’s 4GB of built-in storage without a cloud subscription. Continuous 24/7 recording and expanded AI recognition require a separate HomeBase S380, according to the supplied product information.
Does the S4 work with Apple Home, Alexa and Google Home?
Eufy lists support for Amazon Alexa, Apple Home and Google Home. Apple Home requires the HomeBase S380, and the third-party platforms show a fixed live view rather than the Eufy app’s VR mode or OmniTrack tracking.
When will the Eufy S4 ship, and how much does it cost?
Pre-orders are open, with shipments expected by the end of October 2026. The supplied material lists $299.99 and £69.99, including a Chime 2, but does not explain the difference between those regional prices. Check the current local listing before ordering.
