Hello, 
  
I'm a bit new to this area of IP camera, I have 60 IP cameras Dahua IPC-hfw2300rp-z, and I managed by Smart PSS (PC based solution), but I see a lot of problems: 
-	A huge latency in the transmission of video, 
-	The pc running smart PSS (for a 32 camera view), it becomes heavy and warm (fan does not stop). 
  
I opt for a multicast solution, so I bought CA 2960 POE switchs , and 1945 router, all are set up and connected correctly, the display in internet explorer in multicast mode camera works fine, 
But I cannot add devices in smart PSS in multicast mode, 
And I still have the same latency in the video reception 
  
Is there a solution to my problem? 
  
Cordially
