2026 verdict

The Eufy Cam S4 is the stronger security camera in this Eufy pairing, built around a dual-lens auto-tracking design (355 degree pan, 70 degree tilt) that records in 4K, adds solar charging and 2K, and covers a broader alert set than the older Eufy Outdoor Cam E210. The Eufy Outdoor Cam E210 has clear appeal of its own: it is much more affordable, better rated, carries a tougher IP67 weather rating, and adds Apple HomeKit support the S4 lacks, all while doing dependable wired 24/7 recording with no fee. Both are Eufy cameras with free local storage and RTSP. Choose the Eufy Cam S4 for flagship 4K, pan-tilt auto-tracking and solar power; choose the Eufy Outdoor Cam E210 for a low-cost, wired HomeKit camera that just keeps recording.

The Eufy Cam S4. It records 4K and uses a dual-lens design that pans 355 degrees and tilts 70 degrees to auto-track people, pets and vehicles. The Eufy Outdoor Cam E210 is a fixed 1080p camera that watches a set area rather than following subjects.

Which supports Apple HomeKit?
