eufy 4K NVR S4 Max（無硬碟）

The PTZ camera's 8x auto-zoom actually locks onto motion and follows it smoothly—I've caught clear faces from across the yard. Local AI means it filters out leaves and shadows, so I only get real alerts. Setup was straightforward and the 360° coverage leaves zero blind spots.

Set this up at my shop and the 122° wide lens covers the whole lot while the lower camera handles the tight zoom. The auto-tracking actually keeps up when someone walks the perimeter, which I didn't expect at this price. Footage is crisp enough to read a license plate at the gate.

Watching the PTZ lens auto-zoom 8x onto a delivery truck while the wide-angle camera still covered my whole driveway sold me on the triple-lens design. Both feeds stay sharp at 4K and 2K, and I haven't missed a single motion event yet.
