Wanted to share the fix if your Web server is showing a black / blank stream when 5 or more cameras are activated. Because I never reset and had auto updates disabled i added a 5th camera and it just kept showing up black in my web server.... version 5.0.0.X

Opened settings, clicked check for update, let it run and now all my cameras work in the web server. Current version as of now is 5.0.9.2 and works great.
