This isn't specifically a Crestron question, but the Cameras will be Crestron controlled so I figure it's fair game :)
I've got 3 Axis Q6035 HD IP PTZ cameras that I will be installing in a classroom/lab. There will be around 30 PCs around the lab that need to be able to receive the IP video feed from a user selectable camera. Due to limitations in the Axis camera, only 20 viewers per camera are allowed, so I was going to set the cameras to broadcast using Multicast, that way there's no theoretical limit to the number of viewers.
The issue I'm running in to is that I can't get Windows 7 machines to view the multicast feed! Hooking up an XP machine to the network works perfectly. I've tried 3 Windows 7 machines to far and all have the same issue. Using Wireshark, I have been able to confirm that the Windows 7 machines see the multicast traffic. Viewing is all done via the Axis camera's web interface which is running an ActiveX control called Axis Media Control, which has some options about network configuration and such. Again, works fine on XP, not so much with Win7
Same issue regardless of the state of the firewall.
I've got a ticket open with Axis tech support and they say that things work with their Windows 7 machines.
The only thing that I'm doing at my office that will be different than in the field is the switch - I've just got a non-managed Netgear GS108 in my lab, while there will be a 'real' switch in the classroom that supports IGMP snooping and other multicast friendly stuff. I can't see how that would matter, though, since I can see the multicast traffic on the target machines with Wireshark.
Any suggestions of areas to look into?
Thanks,
Andrew
