I currently have 5 cams in one room in AHP N1 to N5. I believe that if you use the same house code and the cams are all in the same room that turning on any one of them will shut the others off. (Turning on N5 will shut down N1 thru N4 which ever is on and turning on N1 thru N4 will shut down N5)
The key is they need to be in the same room and the switching done from AHP software. I have not tried to use 2 remotes, one set to N1 thru N4 and the other set to N5 thru N8 but it may work? When I get time I will try it.
