2026 verdict
Cellular freedom against dual-lens coverage: wherever Wi-Fi reaches, the Eufy Cam S4 is the stronger Eufy security camera, with 4K, a pan-tilt tracking lens and solar charging.
It pairs a fixed wide lens with a telephoto that pans 355 degrees and tilts 70, stores clips on 32GB built in plus a microSD card, detects people, animals and vehicles, offers RTSP and can record 24/7 when wired. The Eufy 4G Camera S230 exists for places the S4 cannot go: it connects over 4G instead of Wi-Fi, carries GPS, is sealed to IP67 and costs less, but it records 2K with a fixed view, has no solar charging and a battery rated for 3 months. Both keep footage locally with no mandatory plan and work with Google Home, Alexa and Home Assistant. Choose the Eufy Cam S4 for a home with Wi-Fi, and the Eufy 4G Camera S230 for a cabin, a farm or a site with no network.

What owners say
Eufy Cam S4 owners are most taken with the dual-camera tracking: the top lens holds the whole scene while the lower one zooms and follows movement, which many call the best in Eufy's lineup. They also praise the sharp 4K picture with solid color night vision, the solar panel that keeps batteries topped up and the local storage with no monthly fee, along with responsive Eufy support. The complaints are about the 2.4 GHz Wi-Fi, which struggles in crowded apartment networks, vehicle detection that can miss on long driveways, a heavy and slow app after recent updates, some lens condensation in the cold, and no RTSP while the camera runs on battery.
