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. Your smartphone will also work as it has a camera, and there is a Zoom app. But if you're using this for attending classes online, you may not need the camera at all. Other apps include DUO, Skype, Viber, Facetime (iPhone). You can even use that Phone as a webcam if you use Android. The app is called DROID CAM, and you need the DroidCam client for the PC. You can connect over WiFi or USB.
