Eufy Video Doorbell S4: The ‘VR’ Doorbell That’s Still Subscription-Free (2026)
Anker has launched the eufy Video Doorbell S4 — a $299.99 doorbell with 3K 180-degree video, an AI tracking mode, and what eufy bills as ‘VR viewing’ — and it keeps eufy’s most important tradition: no subscription required. On sale since Oct 15, 2026 at Amazon and eufy.com — $299.99 with Chime 2. The 15% pre-order discount has ended. Here is what is genuinely new, what is marketing, and the one limitation that rules out renters entirely.
This is launch coverage, not a review — no independent reviewer has tested a retail unit yet as of 2026-09-30. Every spec below is attributed to eufy’s official product page or named press, and where sources disagree, we say so.
Key Takeaways
- Price: $299.99 with Chime 2 included. On sale since Oct 15, 2026 at Amazon and eufy.com; the 15% pre-order discount has ended.
- The ‘VR’ part is not a headset product — it is a full-screen panoramic navigation UI in the eufy app: tilt your phone to look around the 180-degree feed (an optional VR headset works too). It and the AI tracking only work fully in the eufy app.
- No subscription required — official ‘No Monthly Fee’ banner, 4 GB of built-in eMMC storage. Note: some early press incorrectly reported 64 GB; eufy’s own page says 4 GB.
- The catch: wired-only. It needs existing doorbell wiring (16-24V); no battery mode, no solar. Renters and homes without wiring are out.
- Launch frame rate is 15 fps per eufy’s own FAQ (’24 fps coming soon’), while press reports ‘up to 24 fps’ — both claims, attributed.

What eufy just announced
The Video Doorbell S4 was unveiled at Anker’s small NYC security event in late September 2026, as part of the new Edge 5.0 protection line (five devices including new cameras and a window camera). The S4 is the flagship doorbell of that line: a cylindrical unit with a 3072×3072 3K HDR square sensor, a 180-degree horizontal by 180-degree vertical field of view, and eufy’s headline feature — ‘VR Mode.’ It replaces no existing model; it is a new premium tier above the E340.
For context on the wider eufy doorbell lineup, see our Eufy vs Arlo video doorbell comparison.
What ‘VR Mode’ actually is
Eufy bills the S4 as the ‘world’s first VR doorbell’ — but that is marketing, and the press covering it has been honest about that. GSMDome frames it as ‘a way to navigate the captured panorama rather than a 360-degree recording mode.’ Here is the actual mechanic:
- When a visitor presses the button, your phone rings like an incoming video call.
- Answering opens a full-screen, borderless panoramic feed — no letterboxing, gesture controls, two-way audio.
- Move your phone around to look across the 180-degree view in real time, or wear a compatible VR headset for the full effect.
The important limitation: VR Mode and OmniTrack only work fully in the eufy app. Through Alexa, Google Assistant, or Apple HomeKit you get a fixed live view only. And if your upload speed is weak, eufy recommends 8 Mbps for 3K streaming and 12 Mbps or more for the best experience.
OmniTrack AI: auto-tracking that crops the panorama
The second headline feature is OmniTrack: on-device AI auto-tracking and auto-framing. When the doorbell detects a person, it locks on and automatically crops and zooms the panoramic frame to keep them centered — you keep the wide view for context and get a tight tracked view of what matters. Detection covers people, motion, packages, and faces, using a radar plus dual-PIR sensor combination that eufy says separates human movement from insects and rain. Custom detection zones can be set within a 120-degree field out to 8 meters.

The rest of the Edge 5.0 line
The S4 doesn’t ship alone. Re-verified Oct 19, 2026: the TrackLight Cam S1 ($299.99, shipping by Oct 25) pairs a spotlight with radar; the SoloCam E50 ($229.99, shipping by end of October) is the budget 2K option — a 2-cam kit costs $449.99 and a 4-cam + HomeBase S380 kit $999.99; the eufyCam E52 ($269.99, late October) sits in the middle. A bundle of the S4 with two SoloCam E50s and a HomeBase S380 runs $949.98. The Window Camera E10 ($79.99) lands later this year.
As with the S4, the pitch across the line is no-subscription security — see our eufy vs Arlo comparison for the subscription-free showdown.
No subscription — confirmed, with the fine print
Like the E340 before it, the S4 has no subscription plan to buy. Eufy’s product page carries an explicit ‘No Monthly Fee’ banner: all features work with the 4 GB of built-in eMMC storage. For a model-by-model breakdown, see how long Eufy local storage lasts across the range. Two pieces of honest fine print:
- 4 GB, not 64 GB. Gizmodo’s pre-launch coverage and some CES-era reporting claimed 64 GB of storage — and Gizmodo’s same article wrongly claimed solar/battery power. The official spec page says 4 GB eMMC, Notebookcheck independently reports 4 GB, and the pre-release YouTube reviewer corrected their own video to 4 GB. 4 GB is modest for a 3K doorbell (the E340 has 8 GB), so heavy-traffic doors will loop footage faster.
- Thumbnail cloud storage. The page’s fine print notes that push-notification thumbnail previews require temporary cloud storage of those thumbnails. Video itself stays local.
Eufy’s UK/IE regional pages additionally claim SD expansion up to 1 TB — but the US product page says nothing about expansion, so we are treating that as unconfirmed. If you want expandable storage today, that is what the no-subscription roundup is for.
For the wider picture, see whether eufy cameras need a subscription.
The wired-only catch
This is the S4’s biggest structural limitation, and eufy’s own FAQ states it plainly: ‘This wired-only model does not support daily battery-powered use or solar power.’ It needs existing doorbell wiring (16-24V AC); the 2,600 mAh battery exists purely as outage backup. That makes the S4 a non-starter for renters and for any home without doorbell wiring — which is most of our audience. If that is you, the battery models in our no-wiring doorbell guide are the realistic pick.
How it compares at launch
Putting the S4 next to the no-subscription alternatives we already track (prices verified 2026-09-30):
| eufy S4 (new) | eufy E340 | Reolink Battery (2nd Gen) | Tapo D260 (new) | |
|---|---|---|---|---|
| Approx. price | $299.99 | $149.99 | $149.99 | $219.99 |
| Resolution | 3K (3072×3072) | 2K | 2K (2048×2048) | 4K |
| Power | Wired only | Battery or wired | Battery or wired | Battery or wired |
| Local storage | 4 GB built-in | 8 GB built-in | microSD to 512 GB | microSD to 512 GB |
| Subscription | None required | None exists | None required | None required |
| Standout | VR Mode + OmniTrack AI | Dual camera (visitor + package) | 512 GB microSD ceiling | 4K at $219.99 |
The honest read: the S4 buys you 3K resolution, the widest true field of view here, and two genuinely new interaction ideas — at double the price of the E340, with half the storage and no battery option. The Tapo D260, launched the same week at $219.99 with 4K and microSD, is the awkward comparison eufy would rather you not make.
Who it is for — and who should skip it
Buy it if…
- You have existing doorbell wiring and want the widest, sharpest no-subscription view available.
- The VR-style panoramic navigation appeals to you — it is the only doorbell doing this.
- You are bought into eufy already (HomeBase S380 adds continuous recording and wider AI recognition).
Skip it if…
- You are a renter or have no doorbell wiring — it is wired-only, full stop.
- You want maximum local storage — 4 GB is the smallest onboard storage in this comparison.
- You are price-sensitive — the E340 gives you no-subscription eufy for half the money.
Our research method
No retail-unit review of the S4 exists yet — we did not test it and will not pretend we did. This article is built from eufy’s official product page and FAQ (checked 2026-09-30), launch coverage from Notebookcheck, Tech Digest, gizmochina, GSMDome, channelnews, hi-tech.ua, homekitnews, and the AppleInsider podcast (all late September 2026), plus one independent pre-release YouTube deep-dive whose creator corrected their own storage figure to the official 4 GB. Where press and eufy’s own page disagree (frame rate, storage), we attribute both. Prices and pre-order terms were re-verified 2026-09-30.
Frequently asked questions
Does the eufy Video Doorbell S4 need a subscription?
No. Eufy’s product page carries an explicit ‘No Monthly Fee’ banner — all features work with the 4 GB of built-in eMMC storage, and eufy sells no subscription plan for it. If you’re also considering Ring, see what a Ring doorbell can and can’t do without a subscription — its best features sit behind a plan.
When does the eufy S4 ship?
It’s shipping now — on sale since Oct 15, 2026 at Amazon and eufy.com; retail fulfillment ramped through late October.
Is the eufy S4 battery-powered?
No — it is wired-only and needs existing doorbell wiring (16-24V AC). The small 2,600 mAh battery is outage backup only. This makes it unsuitable for renters and homes without wiring.
Do I need a VR headset for VR Mode?
No. VR Mode is primarily a phone experience — tilt your phone to look around the 180-degree panoramic feed in the eufy app. A compatible VR headset is optional, not required. Note that VR Mode only works in the eufy app, not through Alexa, Google, or HomeKit.
How much storage does the eufy S4 have?
4 GB of built-in eMMC storage, per eufy’s official spec page. Some early press reported 64 GB — that was wrong (the same articles wrongly claimed solar/battery power). At 3K resolution, 4 GB will loop faster than the 8 GB in the E340.
