Multi Port
All browsers currently have a limitation where there can only be 6 connections to a server. This can be gotten around by using multi port, or by adjusting the Firefox about:config setting.
Apache Settings for Multi Port
This is the optimal approach as it will work on any browser. If you are in a commercial setting, or have other users besides yourself, it is almost required to setup Multi Port through Apache. If on the other hand you are on your own, you may consider simply using Firefox. Multi port, does just what it says: It will redirect multiple server connections through different ports, which is a workaround for the browser security limitation.
Here are some quick configs for 50 cameras. Note: The below config has been confirmed to work with only HTTP. Https may need additional configuration. If you get an error about missing > bracket, make it so all these _default_:#### are on one line. Then it will work. It's not easy to read it in that format, so it has been justified for easier viewing here.

Firefox About:Config
In firefox you can make a change to the configuration to get cameras to display. First go to about:config . And search for, then adjust Network.http.max-persistent-connections-per-server. The max persistent connections per server must be > 6 in order to see > 6 camera streams. It can be set to any number, so perhaps you might set it to 100 or 150.
