RSI cam will most definitely NOT be available outside of North America unfortunately. Even though CIG is an international company, the merch is exclusive to USA (though you can still order, shipping cost, import tax, and additional fee will be a thing and could potentially even triple the cost). All webcams should work fine, as long as they do 30FPS at 720p, but 60FPS is recommended for accuracy. I'm currently using a Logitech C920 but I will swap it for a C922 as it doesn't do 60FPS even at 720p (like some stores advertise). What will you go for? Edit: For those that don't know what FOIP is, here's the announcement video (it's a lot better now, you can see some in recent ATVs)
