eufy Video Doorbell S4 Review: Whole-Porch View, No Fees

As an Amazon Associate I earn from qualifying purchases. Disclosure

Overview

Most video doorbells still frame a narrow rectangle of the porch, so a box left on the mat or a visitor standing off to one side can slip out of the picture. The eufy Video Doorbell S4 answers that with a single fisheye lens covering 180 degrees side to side and top to bottom, then uses AI tracking eufy calls OmniTrack to crop in on whoever walks up. It comes with eufy’s Chime 2, saves clips on the doorbell itself with no monthly fee, and sells on Amazon in the US and Canada.

eufy’s previous doorbell, the E340, needed a second, downward-facing camera to watch packages; the S4 covers the doorstep and the visitor with one lens and one image. It went on sale in the US in October 2026. As of October 2026, the only full independent review we found is Gear Diary’s, from a little under two weeks on its own front door with a sample eufy supplied, paired with a eufy HomeBase 3 (the HomeBase S380). This review leans on that test, launch coverage and eufy’s own specs, and credits each finding to whoever made it.

Key Specifications

eufy Video Doorbell S4 Picture and 180-Degree View

That lens is the S4’s main selling point: one picture shows the doormat, the visitor and both edges of the porch at once. Gear Diary, which swapped its own E340 for the S4, preferred that single image to the E340’s two camera panes, called the picture “extremely clear” and had no trouble picking out faces and packages anywhere in the frame.

The 9 MP sensor records a square 3072 × 3072 image, which leaves pixels to spare when the doorbell zooms in; eufy rates its zoom at up to 8×. One spec differs from the launch coverage, which quotes 24 fps: eufy’s own US page says the S4 records at 15 fps for now, with “24 fps coming soon”.

The fisheye picture can also be explored. In eufy’s VR mode you look around the panoramic image by moving your phone or a VR headset, and a ring arrives like an incoming video call that opens straight into that view with two-way audio. TechRadar called VR the “arguably unnecessary headline feature” and judged the rest of the feature list strong enough to justify the price; a regular fisheye view is there if you never use VR.

After dark, the S4 switches to color night vision, and a built-in light glows as someone approaches. Gear Diary scheduled that light for nighttime, and points out that it does double duty: it puts real light on whoever is at the door, for the camera and for a guest walking up. We found no measured night-image test yet.

OmniTrack, Alerts and Package Detection

A fisheye picture this wide would leave a visitor small in the frame, and OmniTrack is eufy’s fix: it crops the panoramic image around a detected person and keeps them in the middle of the shot as they move. In Gear Diary’s use, visitors stayed inside that crop from the end of the path right down to crouching at the mat with a box.

To cut false alerts, the S4 pairs radar, which picks up motion farther out, with dual PIR sensors that sort out human movement closer to the door. Two app settings then decide what earns a notification: a distance limit, so passers-by out on the sidewalk don’t count, and alert areas brushed straight onto the round fisheye picture rather than boxed off. Gear Diary found the pair gave it finer control than it had on earlier doorbells. Those custom zones can cover a 120-degree field out to 8 m (about 26 ft).

Package alerts cover both delivery and pickup; Gear Diary found the pickup alert the more useful of the two, since it tells you a box has just left the porch. A HomeBase S380, sold separately, adds round-the-clock recording and AI that tells people, vehicles, pets and packages apart.

Wired Power, Setup and Smart Home Support

Gear Diary had the S4 replacing its E340 in under 30 minutes, reusing the two low-voltage wires already in the wall, and found the app setup even easier than the hardware. The S4 is wired only: it runs from a 16-24V AC doorbell circuit, and its 2,600 mAh battery is there to keep it working through a power cut, not for daily use.

Clips save to 4 GB of built-in storage with no subscription; for continuous recording, eufy points to a microSD card (not included) or a HomeBase S380. For 3K streaming, eufy recommends at least 8 Mbps of upload speed.

The S4 works with Alexa, Google Assistant and Apple HomeKit, the last only through a HomeBase S380. Outside the eufy app, though, it shows a fixed view: eufy’s US page says video is limited to 1536p in those platforms, and VR mode and OmniTrack aren’t supported there.

How Does It Stack Up Against the Competition?

Here is how the S4 lines up against Ring’s and Google’s wired flagships, on the makers’ own specs.

eufy Video Doorbell S4: Worth It for Whole-Porch Coverage With No Monthly Fee

The S4 earns its place if you want to see everything in front of your door, packages included, in one picture, with clips saved on the doorbell rather than in a paid cloud plan. As of October 2026 it costs more on Amazon than every rival in this table, and the missing monthly fee is where that gap closes. Ring keeps 180-day video history behind its Ring Protect plan. Google’s cheapest paid plan for the Nest Doorbell is $10 a month or $100 a year (October 2026), which overtakes the gap between the S4 and the Nest in a little over a year, even on the annual plan. If you already run eufy cameras or a HomeBase, the S4 sits in the same app as the rest.

Look elsewhere if your door has no doorbell wiring: eufy’s older dual-camera E340, which eufy still sells, can run on its battery or on wires and stores more on board. A Google Home household may prefer the Nest Doorbell, built around Google’s own app and Gemini features, and the Ring Wired Doorbell 4K Pro offers up to 10× Enhanced Zoom, against the S4’s 8×, if you’re happy to pay for Ring Protect. If you mainly watch your door through Alexa, Google Home or Apple Home, the S4’s tracking and VR view stay in eufy’s app, so its biggest advantages won’t show up there.
