Do you want to connect to your camera directly bypassing BI? You should be able to to that on your network. If you have BI you can use UI3 which is a web application to view your cameras.
I was trying to connect my cameras to my Vera network. I installed the blue iris Vera plugin but I was having trouble connecting due to a password requirement. So wanted to be able to modify the URL to include Auth credentials.
You can eliminate the need for login/password based on IP address. I assume your Vera device is local. Bring up Blue Iris, select the Settings, select Web server tab, select the Advanced... button. Under limit access by IP address, enter in a ^ then the IP address, for example:
^192.168.1.130
This will allow the computer at 192.168.1.130 to access a specific camera without using a login/password..., for example, if your Blue Iris computer is at 192.168.1.20 and short camera name is FrontDoor:
