34 ► eufy 4K S4 Max

The eufy 4K S4 Max is my premium, professional-level pick if you want serious coverage and 24/7 recording. You’re getting a triple-lens setup (4K wide angle plus 2K PTZ) with live cross-cam tracking, and it runs local AI with smart search—no subscription fees.

Pros

+Triple-lens coverage: 4K wide-angle plus 2K PTZ
+Live cross-cam tracking to follow movement smoothly
+8-port NVR with 4TB storage, expandable up to 16TB
+Local AI detection and tracking up to 164 ft
+No subscription fees

Cons

-High price compared to other options (around $1,600)
-More of a full system setup than a simple single-camera install
