These 'anti-cheat' softwares don't actually prevent cheating. One of my teachers tried to use one called MyPerfectice (thankfully we persuaded her to switch). I think most of these are built without any understanding of the constraints set up by the browser. I don't know about the others but MyPerfectice gives you 4 or 5 window going out of focus events before making your attempt invalid. The funny thing is that they allow students to upload files from their system and allow focus to be lost during that. So if you click the upload button, it opens the OS file selection window and you are then free from all the checks they set up. Open a new window and cheat as much as you like.

I'm wondering if it's possible to just do a custom build of Firefox/Chrome that does not trigger these out of focus events.

Coming to the video streams, just record a 1-2 minute video of yourself staring into your screen from your webcam and loop it through OBS. No one will notice anything. For MyPerfectice, it is even easier, they have their camera controls exposed as unobfuscated global objects. So you can essentially do something like `camera.stop()` and the webcam light turns off.
