If it has an HDMI output without too much junk on it yes. Sometimes the HDMI output will have the same interface that’s on the screen, sometimes it will be clean, and sometimes it shows the interface but you can shut it off so it doesn’t matter. You can usually crop out the interface in OBS but you’ll lose some resolution doing that. You should be able to plug it into a monitor or TV and check fairly easily.

Hmm I need to do some research. I’m not really sure what these are for or what they do, but I’ll look into it, thanks.

Sorry, probably should have explained. If you have a camera that has an HDMI or other video output they basically convert it to a USB camera.

I’ll look into this as well. Seems like people have had focus issues though, based on reviews I saw.

Most of the models they put out don’t have autofocus at all, you have to physically turn it to focus. Depending on exactly how your setup works that may or may not be viable - overhead cam like for playing magic probably doesn’t move much, but for video conferences where you shift in your chair it might be weird if the room is a bit darker.

If you already have a camera with HDMI output sitting around a capture card can be a great way to get really good image quality for not much money. If 720p is enough I’ve actually had really good success with these incredibly cheap ones: https://youtu.be/daS5RHVAl2U - I’ve even seen them at places like Walmart and Target under the Vivitar brand so they’re readily available.

If you don’t look around locally for used Sony cameras. Because 1080p is only 2 mega pixels and many of the nicer old Sony cameras have clean HDMI output you can get kind of amazing image quality for very cheap. Some newer model mirrorless cameras got updates to run as a webcam directly off the USB port but they’re likely out of your budget and some require software. (Edit: make sure you check if the model you’re looking at has clean HDMI out - some do, some don’t, and some do with some tweaking. This site has a decent bit probably incomplete list: http://wasge.es/clean_output/ )

If you want a more traditional webcam and need autofocus something like the Logitech c920 family is probably your best bet but the constant revisions may have added a software install. Most cameras are including software since realistically they’re all basically the same and most of the “features” are added in the software.

If you don’t need autofocus, there are a number of companies taking Sony “security camera” sensors and slapping them in boxes with screw mount lenses. ELP and Mokose are examples but there are others. With enough light these generally look pretty dang good. If you pick one up and decide later to upgrade, it can probably live mounted up high just for playing magic, especially since there are a few 4k ones that will probably let you read the tiniest of text on the cards.
