Moral of the story: Don't buy Hikvision webcams if you're a Linux user. They work just fine on Windows and Mac systems. I really can't believe a webcam can freeze the entire system including in-browser applications. Hikvision states that their webcams are compatible with Linux but, I'll be the judge of that.
