I've been pretty unhappy with the long USB cables and the plumbing required to wire up a camera for a conference room, or at a home office. There also doesn't seem to be a wide selection available for Wireless Webcams for macOS. Also webcams are much more expensive than their IP Camera counterparts, which are essentially commodity products at this point.
So I built LemurCam (website: lemur.cam) over the weekend. It works great! Minimal latency and you can use any off the shelf camera with it. I'm rocking it with a TP-Link Tapo that I got for like 20 euros. I've had to build some open source tech to make this possible, which is also linked in the repository README file. Overall, this is working well for me and has eliminated the need for USB wiring.
I hope it works for you too! It's free so please give it a go and let me know how your experience goes!
