## Verdict

The eufy Security eufyCam S4 is a cutting-edge outdoor security camera system that shines with superb 4K video quality, versatile triple-lens PTZ capabilities, and no subscription fees. However, the recent app reliability issues and finicky solar charging can dampen the overall experience unless you’re willing to tweak settings and accept some software hiccups. If you want robust, subscription-free security with advanced tracking and solid hardware, this is a strong contender—but if smooth app performance and flawless automation scheduling are deal-breakers, considering a wired alternative might be wise.

You might also want to look into wired floodlight cameras if you want that extra brightness and an always-on power source for guaranteed uptime.

**Top pro:** Offers excellent video quality with clear, sharp 4K UHD footage and advanced autofocus/image stabilization.
**Top con:** Recent app updates have noticeably slowed app performance, making live feeds, event loading, and navigation frustratingly sluggish.
