Systems like Wowza

We have a epiphan Pearl-2 to capture video, screen, etc. Now, if I want all staff to be able to view the live streaming on their own desktops (about 1500 sets), Pearl-2 can’t handle that. Our local network won’t handle that much data flow either.

Suppose we have 10GB network available, it seems that we can setup a Wowza streaming engine (on-permise) and let staff connecting to it (instead of the Pearl-2 directly). All streaming data will not go through the Internet as well.

Am I correct about the above setup?

Besides Wowza, any similar products that can do the similar?

Many thanks.
