   I don't know what that means.  Are you using a Web browser on a
computer, or some app on a phone, or what?  What's "the CM network of
the cameras"?

   It's not "my internet", it's your local-area network (LAN).  The
Internet is a collection of many interconnected smaller networks (like
yours).  Hence the name.  But I digress.  What does "the item CM number"

mean?

   At least one of us is confused, and only one of us knows which book
the other should be reading.  And I'm not the one with that info.
