In this video, I unbox and fully test eufy’s new S4 Max PoE NVR security system—because this is a big shift for eufy. They’ve been known for Wi‑Fi cameras, but a wired PoE NVR setup is a totally different tier for reliability, consistency, and “set it and forget it” recording. I walk through what’s in the box, how the install and setup actually goes in the real world, and what you can expect from the cameras and the NVR once everything is up and running. I also demo the stuff people really care about: night vision performance, the camera speaker, the NVR interface, and how the eufy app ties into the experience. Then I lay out my pros and cons, including a specific caution about the spotlights—because features like that can be awesome, but they can also create unintended problems depending on where you mount the cameras. If you’re deciding between a DIY PoE kit like this and a more traditional wired system, this review should help you figure out whether the S4 Max is the right move for your house.
