The modern front door has a lot to juggle. Couriers drop parcels, friends arrive unannounced, kids race in and out, and somewhere in the background, there is a quiet worry about missing something important or not catching something suspicious. Many homes already have a patchwork of doorbells, lights, and locks that only half cooperate, or lean heavily on cloud subscriptions and frequent battery swaps that never quite stop being a chore.
eufy’s CES 2026 security lineup treats that threshold as a single design problem. The Video Doorbell S4, Solar Wall Light Cam S4, and Smart Lock E40 share a few big ideas: higher‑resolution cameras, AI and radar‑assisted detection, and power systems built to run for months or indefinitely, while keeping most of the intelligence and storage local instead of streaming everything to a server somewhere far away.

eufy Video Doorbell S4
The Video Doorbell S4 is the greeter. It wraps a 3K sensor into a 180‑degree horizontal and vertical field of view, which means it can see from the ceiling down to the doormat and across the entire porch in one shot. That panoramic view captures faces, packages, and anyone standing off to the side, so you are not left guessing whether a delivery was left just out of frame.
eufy’s OmniTrack technology and built‑in radar focus on people rather than every passing car or branch. As someone approaches, radar detects motion and distance, then AI locks on and adjusts the zoom so the visitor stays centered, whether it is a courier bending to drop a parcel or a neighbor walking up the path. The 3K clarity holds up to around 26 feet, with 16 GB of local storage keeping recordings on the device.
eufy Solar Wall Light Cam S4
The Solar Wall Light Cam S4 is the guardian that wraps light and vision around the entryway or side yard. It combines a 4K camera with an f/1.6 lens and a vertically adjustable mount, up to 45 degrees, so it can look down into blind spots near the wall while still watching the approach. The 4K resolution and color night vision make faces and details legible even when the only illumination is the light itself.
Power is handled by a detachable 2 W solar panel feeding a 10,000 mAh battery, which gives freedom in where you mount it. The panel can sit where the sun actually hits, while the light and camera stay where they are most useful. Multiple lighting modes let the fixture shift roles, daily illumination for paths, brighter security lighting when motion is detected, and festive RGB scenes that turn the same hardware into holiday decor.
eufy Smart Lock E40
The Smart Lock E40 is the final layer at the door, replacing keys and fingerprints with 3D face recognition. A quick glance is enough to unlock for pre‑registered users, which matters most when your hands are full of groceries or luggage, and you would rather not dig for keys or touch a screen. A built‑in 2K camera with a head‑to‑toe view records who is at the door, aligning the lock with the rest of eufy’s camera‑centric security story.
The E40 runs on a PowerDuo system, a 15,000 mAh main battery backed by an 800 mAh reserve that keeps the lock alive during swaps or unexpected drain. It is rated IP65 for weather resistance and carries ANSI/BHMA Grade 2 certification for mechanical security. On the software side, it speaks Matter, Apple Home, Amazon Alexa, Google Home, and Samsung SmartThings, sitting comfortably inside a broader smart‑home setup while doing most recognition and storage locally.
eufy at CES 2026: A Front Door That Thinks for Itself
These three products sketch out eufy’s view of the front door in 2026, not as a collection of unrelated gadgets, but as a layered system where the doorbell tracks arrivals in 3K, the wall light extends 4K color vision and ambient lighting without new wiring, and the smart lock recognizes faces and controls access while adding its own 2K camera. The common threads, higher‑resolution optics, AI and radar, generous batteries and solar, and local‑first design, make the entryway feel less like a tangle of hardware and more like a single, thoughtful interface between home and street.
