Can you have multiple live streams at once?

Hello, 

I'm looking into purchasing Adobe Media Server 5 and can't find any information on if you are able to have two different live streams running at the same time. In my scenrio, I need two 24/7 live streams that are capturing two different IP cameras. I read through the white paper for Adobe Media Server 5 and saw that it does support 24/7 live streaming but can't seem to find my answer. If it does support multiple streams can I get away with purchasing the standard version or is the professional version needed? 

Any help is appreciated. 

Thank you,
