Anker has announced the eufy Video Doorbell S4, a wired doorbell with a 180-by-180-degree panoramic lens, 3K recording and OmniTrack AI person tracking. Priced at $299.99 with a Chime 2 included, it is available for pre-order now with shipments expected by the end of October 2026.

Anker has announced the eufy Video Doorbell S4, a wired video doorbell built around a 180-by-180-degree panoramic lens and an AI tracking system the company says keeps visitors centred in frame automatically. Priced at $299.99 / £69.99 with a Chime 2 included, the S4 is available for pre-order now, with eufy expecting shipments by the end of October 2026.

The doorbell’s panoramic feed covers the doorstep from floor to ceiling and wall to wall, a wider view than the narrower rectangular frame of most video doorbells. Owners can pan through that view by moving a phone or VR headset, and eufy bills the S4 as the world’s first VR doorbell: each ring arrives like an incoming video call that, according to the company, opens the feed in full-screen VR mode with two-way audio.

Once someone is in view, eufy’s OmniTrack AI system locks on to that person, and auto-framing crops the panoramic image so they stay centred in a tighter shot of each event. The camera records 3K video in a square 9MP frame (3072 x 3072) at up to 24 frames per second with HDR, and offers up to 8x zoom plus dual spotlights for colour night vision.

Detection combines radar for longer-range movement with two PIR sensors closer to the door — a pairing eufy says separates people from false triggers such as insects and rain. Owners can draw custom detection zones within a 120-degree field out to eight metres, and the doorbell detects people, motion, packages and faces. The S4 runs entirely on existing 16 to 24 VAC doorbell wiring, with no battery or solar options; a 2600mAh battery serves only as backup during power cuts.

There is no cloud subscription required: clips are stored on 4GB of built-in storage, while adding a HomeBase S380 unlocks continuous 24/7 recording plus AI recognition of people, vehicles, pets and packages. The S4 works with Amazon Alexa, Apple Home and Google Home, though Apple Home requires a HomeBase S380, and all three platforms show only a fixed live view without VR mode or OmniTrack.

The developmentAnker has announced the eufy Video Doorbell S4, a panoramic-lens video doorbell with AI person tracking, opening pre-orders ahead of shipments expected by the end of October 2026.

What the S4 Changes for Doorbell Cameras

The S4 pushes a design shift in a category where most video doorbells still use a fixed, rectangular wide-angle frame. A panoramic lens combined with AI cropping could reduce the classic doorstep blind spots — packages left at the edge of frame or visitors standing close to the door — without requiring owners to manually zoom or reposition a camera.

The no-subscription stance also matters to buyers weighing long-term costs. Local storage on the device, with optional HomeBase expansion for 24/7 recording, keeps footage out of recurring cloud fees, a positioning eufy has used to compete against subscription-reliant rivals. However, the $299.99 US price places the S4 at the premium end of the doorbell market, and the wired-only design limits installation to homes with existing doorbell wiring.

eufy’s Edge 5.0 Range and HomeBase Strategy

The S4 is part of eufy’s Edge 5.0 range of five devices, built around the HomeBase S380 hub, which adds continuous recording and on-device AI recognition of people, vehicles, pets and packages. Frank Zhu, General Manager at Anker eufy, said homeowners see their property as “one cohesive space they need to protect” — the framing the company uses to sell the hub-and-accessory ecosystem rather than standalone devices.

The VR integration marks an unusual step for the category. While eufy promotes the VR calling experience, it is confined to the eufy app; third-party platforms including Alexa, Apple Home and Google Home display only a fixed live view.

Claims Awaiting Real-World Testing

Several claims rest on eufy’s own descriptions and have not been independently tested: the effectiveness of OmniTrack AI tracking in keeping people centred, the accuracy of the radar-plus-PIR system in filtering false triggers from insects and rain, and the practical usefulness of the VR video-call experience. The “world’s first VR doorbell” label is the company’s marketing claim, not an independently verified distinction.

It is also unclear how much of the 4GB built-in storage fills before older clips are overwritten, how the S4 performs in low light despite HDR and spotlight claims, and whether third-party platform integrations gain tracking or panoramic features later. eufy has not detailed regional availability beyond the quoted US and UK pricing, and the large gap between the $299.99 and £69.99 prices is unusual enough that buyers should confirm local pricing at checkout.

Pre-Orders, Shipping and Reviews to Watch

Pre-orders are open now, and eufy expects shipments by the end of October 2026. Early adopters will need existing 16-24 VAC doorbell wiring; homes without it would need an electrician or a different doorbell, since the S4 offers no battery or solar power options.

In the coming weeks and months, expect hands-on reviews testing the tracking, night vision and false-trigger filtering claims, plus clarity on regional pricing and availability of the broader Edge 5.0 range. Buyers invested in Apple Home should factor in the required HomeBase S380 purchase for compatibility.

Key Questions

How much does the eufy Video Doorbell S4 cost?

Anker has priced the S4 at $299.99 / £69.99, with a Chime 2 included in the box. Pre-orders are open now, with shipments expected by the end of October 2026.

Does the eufy S4 require a subscription?

No. Clips are stored on 4GB of built-in storage. Adding a HomeBase S380 hub unlocks continuous 24/7 recording plus AI recognition of people, vehicles, pets and packages, but there is no mandatory cloud fee.

Is the eufy S4 battery powered?

No. It draws power from existing 16 to 24 VAC doorbell wiring. A 2600mAh battery exists only as backup during power cuts, and there are no battery or solar power options.

Does the eufy S4 work with Alexa, Apple Home and Google Home?

Yes, but with limits. Apple Home requires a HomeBase S380, and all three platforms show only a fixed live view — without VR mode or OmniTrack tracking, which are exclusive to the eufy app.

What does the 360-degree AI tracking actually do?

The 180-by-180-degree panoramic lens captures the whole doorstep, and eufy’s OmniTrack AI locks on to a person and auto-crops the frame so they stay centred in a tighter shot instead of appearing as a distant figure. Real-world performance has not yet been independently tested.
