Hi Thanks for the answering the question,

Yes it is easier with VSMS but VSMS only use unicast with end device and in my senerio take all those streams from VSMS servers puts alot of procces to VSMS. I need multicasting for analytics. In this deployment i use 4ru servers and only HD cameras so taking feeds directly form camera using multicasting seems the best solution. Thanks for the guide. By using wireshark i was able to get necessary URL and now able to recieve multicast feed from camera and play it back with VLC.

Thanks again for information.

Sure its not a problem,

open wireshark and log on to camera web page,
Than press the capture button at wireshark and press the view video button at the web page
Stop the capture at wireshark
On the logs look for a line with an info section starting with

"OPTIONS rtsp://XXX.XXX.XXX.XXX:554/StreamingSetting?version=1.0&sessionID=809081... RTSP/1.0"
Open VLC
Press Ctrl+n
Paste the link


And you will get your Multicast stream.

For analytics, software team wrote a code, i think its C# or maybe c, by using API they log on to the camera get a session id past it to the URL and get the multicast stream directly from camera.

One bad thing about this is number of sessions are limited to 10 even though its a multicast stream i am not able to take the 11th stream from camera.

  • Cisco Employee,

In order to get a session ID I logged into the camera (IP  and went to stream settings and looked for a session ID in the url,  in my case for this session only it was 28333424:

I am using a Mac (safari) and don't have access to IE but I got the session ID and built the URL for VLC:


Only thing I changed was the sessionID, the IP address - everything else on the camera was factory and

I am running firmware version: 2.3.0-188

I then pasted that into VLC ( I am running the Mac Version 1.1.11 The Luggage (Intel 64bit))

At this point VLC crashed.

So I enabled Channel 2 on the camera and enabled SRTP with the defaults and tried that with VLC using with this URI:


Same session ID from above (I didn't log off or close the browser on my mac to the 4500 camera)

This worked for me using Channel2 - there seems to be a bug in the mac vlc version for channel 1.

I also tried the little bit of testing from bcc above with:

but that won't give me a session ID all I got is:
