Irwin's wife is using Zoom for attending class. But suddenly, they can't get a webcam delivered. Leo says that Amazon is prioritizing important things like TP and food delivery right now, so you may have to wait. But if you have a laptop with a camera, you can still chat. Or, you can connect your DSLR to your computer with a live HDMI cable and use it as your webcam. A camcorder will work as well. But if your computer doesn't have an HDMI IN option, then you may need to get an HDMI to USB adapter.
Pete wants a camera that he can stream little league hockey games on. Leo says he'll need a camera with live HDMI out. Most video cameras will do this, and with excellent quality too. Then he'll need a laptop that is able to take HDMI in and then stream it over the internet. The camera really isn't the hard part.
