i have on cmera the out put is hdmi i want to stream this to server by cat5 how can i do?

You cannot do that with this item. This does not convert hdmi video into streaming video for playing over a network. It only plays hdmi video over cat5 wiring between the 2 boxes. To do what you want you'll need to look into products that do video streaming conversion.

I am looking to hook up multiple monitors to a a single source can it be done with this item if I buy more than one. Would I require a splitter?

This is a one to one extender. If you want to go to multiple monitors you would have to have a splitter in place before going into this extender. In going from a Mac to a Projector I did have to change the dial on the side to the greatest distance and I did have to manually set the type of system it was connecting to. Also the power goes on the receiving end not the sending end. Those were a few things that got me in the setup. Now though it works great.

What is included in the package of the StarTech.com ST121SHD50?

What is the maximum distance for HDMI transmission using Cat5e cabling?
