In this video I’m unboxing and fully testing the upgraded FoMaKo K20UH 4K PTZ, and I’m looking at it the way most of you actually use these cameras: for churches, conferences, education, and clean live-streaming setups where you need good image quality, reliable control, and fast setup. I walk through what’s in the box, all the connectivity (HDMI 2.0, network/PoE, and control options), and then I put it through real tests—image quality, IR remote, PTZ presets, autofocus, and a full optical vs digital zoom run so you can see what’s usable and what’s just “marketing zoom.” The big feature here is AI Auto Tracking Gen 3, and I spend time showing how it behaves in different scenarios and what you can actually tweak—tracking modes, sensitivity, subject size, framing/character position, and what it does when it loses the target. I also go deep in the menus (camera, PTZ, video format, network, firmware) and then jump into the web UI so you can control it like you would in a real install. Finally, I show NDI setup inside OBS so you can get it into your production workflow without guessing. If you’re shopping “best budget 4K PTZ,” this is the kind of walkthrough that tells you if it fits your rig before you buy it.
