Video doorbells have not changed much in years: a small vertical rectangle of video that cuts off your visitor's head, your packages, or both. Anker's smart-home brand eufy is now betting the next leap is a completely different way of looking through your front door. It has launched the eufy Video Doorbell S4 — billed as the world's first VR doorbell — with a 180-degree panoramic camera and AI tracking that follows visitors across your doorstep. It costs $299.99 with an included chime, shipping in eufy's new Edge 5.0 security lineup.
The launch matters for more than gadget watchers. Doorbells sit at the intersection of three big smart-home trends: cameras getting smarter instead of just sharper, subscription-free local storage, and AI moving from the cloud into the device. Whether the S4's VR viewing is a genuine breakthrough or clever marketing, the direction it points in is real.
What the eufy S4 actually is
The eufy Video Doorbell S4 is the flagship of Anker's new Edge 5.0 Yard Protection System, a five-device security range that also includes the SoloCam E50, TrackLight Cam S1, eufyCam E52, and Window Camera E10. eufy first showed the S4 at CES back in January at $279.99 — the price has since crept to $299.99 with the eufy Chime 2 included.
On paper, the hardware is a serious step up from a typical doorbell camera:
- 3K HDR sensor: a square 3072 x 3072 image, roughly 9 megapixels, recording at up to 24 frames per second.
- 180-degree lens, both ways: the ultra-wide lens covers 180 degrees horizontally and vertically, which eufy says gives a floor-to-ceiling, wall-to-wall view — visitors from head to toe, packages on the ground in the same frame.
- Up to 8x zoom for getting a closer look at faces or delivery labels.
- Dual spotlights that enable color night vision and throw a warm welcome light when someone approaches.
- Radar plus dual PIR sensors for motion detection, sensing movement up to 8 meters away.
- Smart detection types: the camera can distinguish between people, general motion, packages, and recognized faces, with custom detection zones set within a 120-degree area.
- Ecosystem support: it works with Amazon Alexa, Google Home, and Apple HomeKit — though HomeKit requires the separate HomeBase S380 hub, and the headline features only work inside eufy's own app.
One review of the launch mentions a 2,600 mAh backup battery, but that detail appears in only some early coverage — treat it as unconfirmed. Shipping is listed for the end of October 2026, with pre-orders open now.
What "VR doorbell" really means
A small dose of skepticism helps here. "The world's first VR doorbell" is Anker's marketing claim, and it deserves unpacking — the S4 is not projecting holograms on your doorstep.
Here is how it actually works: when someone presses the doorbell, your phone gets a notification that looks like an incoming video call. Answer it, and you get a full-screen panoramic feed instead of a fixed video window. You then physically move your phone — tilt it up, down, or sideways — and the view pans around the 180-degree image, as if you were looking through a window rather than at a camera. A VR headset works too. Two-way audio runs at the same time, so you can talk to your visitor while scanning the surroundings.
In other words, "VR" here means a navigable wide-angle view, not immersive virtual reality. It is closer to the way you pan around a 360-degree photo on your phone than to an actual VR experience. It is still a real usability upgrade — traditional doorbells force you to look through a fixed peephole, and the panoramic view genuinely removes blind spots at the sides and at floor level where packages sit.
One correction to some early headlines: the spec is 180 degrees horizontal and vertical — half a sphere, not a full 360-degree circle. Impressive for a doorbell, but not true 360-degree imaging.
OmniTrack: the AI that keeps visitors in frame
The more consequential piece of the S4 may be the AI, not the VR. eufy's OmniTrack system locks onto a person in the frame and automatically crops the panoramic image so that person stays centered as they move — like the auto-framing on a good video-conferencing camera, applied to your front door. The camera watches the whole wide scene, but the view you actually look at follows the person who matters.
This solves a genuine pain point. Wide-angle doorbells have always had a paradox — the wider the view, the smaller any individual person appears in it. AI tracking lets the S4 have it both ways: the full panorama is recorded for context, while the view you look at follows the action. The radar-plus-PIR detection stack does the heavy lifting: radar senses movement patterns out to 8 meters, while the dual passive-infrared sensors confirm heat signatures, so the system is less likely to be fooled by swaying branches or headlights. AI tracking claims still need real-world testing — person detection that works in a demo can stumble with unusual clothing, obscured figures, or bad weather.
Price, packaging, and the subscription question
The S4 sells for $299.99 standalone with the eufy Chime 2 in the box; a bigger bundle with two SoloCam E50 cameras and a HomeBase S380 hub costs $949.98. The S4 works with the HomeBase S380 for local storage — and that is where eufy's pitch gets interesting.
Anker's smart-home chief Frank Zhu says the whole Edge 5.0 range connects to the HomeBase for local storage with no monthly subscription. That is a direct shot at the industry standard: Ring's video history and many of Google Nest's smarter features sit behind monthly plans, and those plans often cost more than the hardware over a few years.
There is a tradeoff worth noting. The advanced features — VR viewing and OmniTrack — only work in eufy's own app, so the device nudges you deeper into eufy's ecosystem. HomeKit users will also need the separate HomeBase S380 gateway. It is the familiar lock-in calculation: you save on subscriptions, but you buy into one company's platform.
How it compares to Ring and Nest
Strictly on verified launch details, the S4's headline differentiators are the panoramic 180-degree sensor, the navigable VR-style viewing mode, and AI auto-framing — none of which Ring or Nest currently offer in a doorbell. The advantage is also structural: no subscription for local storage means a $299.99 one-time purchase can undercut the incumbents' total cost of ownership within a couple of years.
What the S4 has not yet proven is reliability and software polish. Ring and Nest benefit from years of refinement, enormous installed bases, and deeply tested alert logic. A first-generation feature set often needs a firmware update or two before it performs the way launch coverage suggests.
Where smart doorbells are actually heading
Zoom out, and the S4 looks less like a novelty and more like a preview. Three shifts are converging on the humble doorbell, and the S4 embodies all of them.
First, AI is replacing resolution as the arms race. For a decade, every camera generation promised more megapixels. The S4's 9-megapixel sensor is good, but the story eufy is really selling is what the AI does with the pixels: track people, ignore cars, recognize faces, spot packages. The camera is becoming a sensor for software, not the product itself. That mirrors the wider consumer-AI trend — intelligence is moving into ambient, always-on gadgets, as Amazon's Bee wearable devices also show.
Second, the subscription model is under pressure. eufy's no-monthly-fee pitch resonates because consumers are waking up to the real cost of subscription hardware. A doorbell that costs $300 once is increasingly attractive next to one that costs $100 plus a monthly fee forever. Expect the incumbents to defend subscriptions with exclusive AI features, while challengers like eufy use "no subscription" as their main battering ram.
Third, privacy and local processing are becoming features. Processing video locally on a HomeBase hub instead of streaming everything to a cloud server is a genuine privacy advantage — your footage never leaves the house unless you choose. But AI face recognition at your front door is powerful technology in a very sensitive place, and it raises questions no marketing sheet answers: who trains on this data, how long is it kept, and what happens if the hub is stolen? Local storage helps, but the rules around facial recognition at home are still being written.
The smart-home landscape is shifting fast — Apple's latest smart-home event signaled that even the biggest platforms are taking the connected home more seriously than ever. The doorbell is becoming a flagship device in that battle, not an afterthought.
The verdict: gimmick or glimpse of the future?
The "world's first VR doorbell" label is marketing, and should be read as such. But strip away the hype and the S4 is still one of the more interesting doorbell launches in years: a genuinely wide panoramic sensor, AI tracking that solves the wide-angle paradox, radar-assisted motion detection, color night vision, and no monthly fee attached.
The open questions are the ones no launch coverage can answer yet: how well does OmniTrack perform in rain, at night, or with a crowd at the door? Does the VR-style viewing stay fun after the novelty wears off? And will the subscription-free promise hold as the AI features get more expensive to maintain? Those answers will come from independent reviews after shipping begins.
If you are in the market for a doorbell right now, the S4 is worth a look — especially if subscription fatigue has you shopping for alternatives to Ring and Nest. Just go in with clear eyes: you are buying into eufy's ecosystem, and the "VR" is a clever viewing mode, not a revolution. The revolution is quieter and more interesting: AI that watches your doorstep and only bothers you when something actually matters.
