How do I add more IP cameras to my Flux XVR?

Firstly verify the specification of your XVR and confirm the device actually supports more IP channels.  Most XVR's have a maximum capability when it comes to how many IP channels they support. 

If your XVR support more IP channels than you have used but you do not have the option to add more you may have to change some of your analog channels over to IP.  To do this go to the "Settings" -> Select Camera -> Select Camera signal and change the channels over from Analog to IP.
