[gello 0]

Hi,

 

I'm new here, is this possible, i have dahua intercom (vth1560bw and vto6210bw) now i want to integrate the ip camera from other source, if the user press the intercom button outside the live video that will calling or appear on vth1560bw (inside) monitor is the the ip camera not the camera from the vto6210bw(outside) itself? i hope you get my idea..

 

Thanks in advance,
