Our take on the eufyCam S4 2-Cam Kit + Video Doorbell E340

A two-camera bundle built around the eufyCam S4, a triple-lens camera that pairs a fixed 4K wide bullet view with a 2K dual-lens PTZ head that pans 360° and tracks subjects up to 164 ft away. The kit adds the Video Doorbell E340 for the front door. The S4 runs on its own with on-device AI for human and vehicle detection and a 5.5W solar panel that keeps it charged from about an hour of direct sun a day, so no HomeBase is required. It suits homeowners who want one camera to cover a wide yard and zoom in on movement without running two separate units.

About the eufyCam S4 2-Cam Kit + Video Doorbell E340

This kit includes two eufyCam S4 cameras and the eufy Video Doorbell E340. Each eufyCam S4 combines a fixed bullet lens and a PTZ camera in one device. The 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, capturing detail up to 164 ft away. If more subjects enter the frame, it zooms out to keep them all in view. A 5.5W solar panel with SolarPlus™ 2.0 keeps the camera charged, and it needs 1 hour of direct sunlight a day. Radar and PIR sensors detect motion. In a set zone or schedule, red and blue warning lights and a 105 dB siren activate.

The Video Doorbell E340 has two cameras. The front-facing camera focuses on people, and the downward-facing camera shows the floor in front of the door. It records in 2K and has a color night vision system with a clear viewing distance of up to 16 ft (5 m). It runs on a quick-release battery or in wired mode, where the wired power source tops up the battery.
