I built this macOS app that allows you to use any off the shelf wifi camera as your webcam with Zoom, Microsoft Teams, etc. It has lower latency than OBS, VLC etc based on my testing, its Swift-Native and pretty lightweight.

It was built mainly for my own team so they don't have to run long wires of USB cameras or pay a lot of money for a "wireless webcam". I hope you find it useful!
