Aqara Camera G100 vs Eufy Cam S4

The Eufy Cam S4 is the better overall camera, with 4K video, solar charging, a dual-lens 355-degree pan and 70-degree tilt auto-tracking design, and generous local storage. The Aqara Camera G100 wins decisively on price and adds native HomeKit, privacy zones and more alert types, making it the value alternative.

Capability and format separate them. The Eufy Cam S4 is a premium 4K solar pan-tilt camera that physically tracks movement and stores a lot locally, while the Aqara Camera G100 is a compact, fixed, wired 2K camera at a much lower price with native HomeKit support.

The Eufy Cam S4 can, thanks to a motorized head that pans 355 degrees and tilts 70 degrees with auto-tracking, plus a dual-lens setup. The Aqara Camera G100 is a fixed camera with a 140-degree field of view, so it watches a set area rather than actively following subjects.

The Eufy Cam S4 records in 4K, a clear step above the Aqara Camera G100's 2K. Both include color night vision and RTSP, but for maximum daytime detail and cropping room the Eufy is the sharper of the two.

Buy the Aqara Camera G100 if you want an affordable, well-rated HomeKit camera with 2K video, privacy zones and broad platform support, and you do not need pan-tilt or 4K. It is ideal for budget-focused Apple households mounting near power.

Buy the Eufy Cam S4 if you want a flagship outdoor camera with 4K video, solar charging, pan-tilt auto-tracking and plenty of subscription-free local storage. It suits buyers who want the most coverage and detail from a single unit and do not mind the higher price.
