VIISANP4H 2-in-1 4K 13MP Document Camera & Webcam with HDMI/USB Dual Mode, A3-Size Capture, Built-in Microphone, 30X Digital Zoom for Teachers, Distance Teaching & Learning, Web Conferencing

Good camera sensor. Some flaws with Mac system. Does not have Wi-Fi and battery.

This is as versatile as I had hoped. Well, for the most part. The base is weighted, so it won't tilt over accidentally - this is both good and bad. Good if you don't want to travel with it. I'm a bit sorry I didn't get the other version that is lighter for travel.The image quality is decent. I like that the height is adjustable with a pretty good range, and I really like having control buttons on the device for getting the image orientation correct, and even manual brightness adjustment and a freeze frame button.The digital zoom is functional, but does get noisy at higher settings.Once disappointment is that it outputs either through USB or HDMI, not both at the same time. Not a huge deal, I mean I haven't even figured a use case for both at the same time. But I do like that there is the option of either.The built in light for the document camera is meh. It is adjustable in steps. But not color adjustable to match ambient white balance as far as I can tell. And like all "on camera" lights, it is prone to making glare on shiny surfaces.Overall, this is very useful.

True 4k video. Very sharp
