Our take on the eufyCam S4 + Video Doorbell E340

A two-camera bundle: the eufyCam S4 is a solar-powered outdoor camera that pairs a fixed 4K wide lens with a 2K dual-lens pan-tilt head, so one unit covers a wide view and tracks and zooms on subjects up to 164 ft away. The Video Doorbell E340 adds a 2K door view with a second downward-facing lens for packages. Neither needs a HomeBase, and both run on-device AI for human and vehicle detection. It suits homeowners who want one camera to do the job of a fixed bullet and a PTZ, plus a doorbell that watches the doorstep.

About the eufyCam S4 + Video Doorbell E340

This bundle pairs the eufyCam S4 security camera with the eufy Video Doorbell E340. The eufyCam S4 combines a bullet camera and a PTZ camera in one device. Its upper 4K bullet lens gives a fixed 130° wide view. The lower 2K dual-lens PTZ camera offers 360° tracking and zoom.

When the bullet camera detects a subject, the PTZ camera locks on, tracks and zooms in to capture details up to 164 ft away. It zooms out automatically when more subjects enter the frame. Radar and PIR sensors detect motion. Within a set zone or schedule, red and blue warning lights and a 105 dB siren activate when a threat is detected. A 5.5W solar panel with SolarPlus™ 2.0 keeps the camera charged, and 1 hour of direct sunlight a day keeps it running.

The camera works on its own with on-device AI for human, vehicle and pet detection. With a HomeBase™ S380, BionicMind™ AI can tell family from strangers. The Video Doorbell E340 has two cameras: a front-facing one for people and a downward-facing one that shows the floor in front of the door. It records in 2K and has color night vision with a clear viewing distance of up to 16 ft (5 m). It runs on a quick-release battery or in wired mode.

Questions and answers

Does the eufyCam S4 need a HomeBase?
No. It works on its own with on-device AI for human and vehicle detection. A HomeBase adds centralized storage and is optional.
How does the S4 compare with a separate bullet and PTZ camera?
It combines both in one unit: a fixed 4K wide lens plus a 2K pan-tilt head that locks on and zooms. That means one mount, one power source and one feed instead of two cameras.
How much sun does the solar panel need?
eufy says about one hour of direct sunlight a day keeps the camera running. Shaded mounts or short winter days will need more, so place the panel where it gets sun.
What does the Video Doorbell E340 add?
A 2K door view plus a second downward lens aimed at the doorstep, so you can see packages as well as visitors. It also runs without a HomeBase.
Where is footage stored?
On-device storage via a microSD card, or in a eufy HomeBase if you add one. There is no required subscription for basic local recording.
Can the S4 track more than one person?
Yes. When more subjects enter the frame it zooms out to keep them all visible, then zooms back in when the view clears.

At eufy, for $499.98, as of our latest check.
