I'll give here my experience installing this kind of files in azbox with DCC
1-open dcc(of course)
2-menu "tools" here in left side bar choose "ipkg packages"last choice presented in screen
3-now in your right side you have a simbol like a open folder"upload packages"
4-Here you should choose the folder where you have yours ipk files and that will start installing.
5-After installing you'll see in dcc screen "Done" thats all
Note:this is what i use to do for every plugins,skins,cams etc for azbox, that's a easy way to proced, that't related to my experience and works nice.
