What the differences mean
Power at the mount
The Eufy Cam S4 has a battery, solar charging and wired power. Continuous history is listed only when it is wired. Battery life itself is not documented. The Eufy Outdoor Cam E210 is wired only, with no battery and no solar. A spot with no outlet can take the S4. A spot with a socket can take either, and only the wired state unlocks 24/7 history on the S4.
One lens or a tracking head
The Eufy Cam S4 combines a 130 degree wide view with a 46 degree telephoto, and it pans 355 degrees and tilts 70. It is 4K with color night vision and a light. The Eufy Outdoor Cam E210 is fixed, 1080p, 108 degrees horizontal, with color night vision and a spotlight. Following someone down a drive is the S4. A steady view of a gate is the E210.
Weather rating
The Eufy Outdoor Cam E210 is IP67. The Eufy Cam S4 is IP65. Both are outdoor cameras. The E210 is the one rated for harsher water and dust. That is the main spec the simpler camera wins, along with price, not the picture.
What is stored on the camera
The Eufy Cam S4 has 32 GB built in, a microSD slot and RTSP. The Eufy Outdoor Cam E210 has 8 GB built in, a microSD slot, RTSP and 24/7 history as a standard feature, not only when wired. Cloud on both is a subscription. Privacy zones are listed on the S4. They are not documented on the E210.

What owners say
Owners of both like Eufy storage that does not start with a monthly fee, then they describe different cameras. Eufy Cam S4 owners single out the wide lens staying put while a second lens zooms and follows, plus solar that keeps the battery topped up, and they complain about 2.4 GHz dropouts in busy Wi-Fi, a heavy app, and vehicle detection that misses a long driveway. Eufy Outdoor Cam E210 owners praise an easy magnetic mount, local 24/7 recording and detection that tells people from animals, and they complain about a dim spotlight, 1080p as the ceiling, and a lag before a clip will play.
