I'm working in a healthcare setting and trying to implement simulation training in our clinical areas. As such, I need a portable system that I can use in a variety of spaces to record the simulation and allow observers to watch from a separate room.

My plan is to use at least 3, potentially 5, PoE IP cameras (to eliminate the need for power points) streaming to a vMIX laptop over a network cable. I *believe* I can use multiple cameras in this way, using 100mB/sec per camera. Without any prior knowledge in this area, I hope that I'm not going to find out I'm restricted to only 1 IP camera stream because as much as the NDI cameras look easier to use, we can't afford the price tag on those.

I also need to mirror an iPad display (used as a patient monitor) which I think will run through an apple TV HDMI connecting to a laptop via a BlackMagic Ultrastudio Mini Recorder and a Thunderbolt port.
We'd leave the patient monitor stream permanently in one corner and then swap between the video feeds depending on what's happening and which cameras have views of the action.

I've seen the topic talking about laptops to stream in 720p but I'm not sure if the talk about requirements for that apply in our situation? I only need to record locally (to facilitate the debriefings) and to output to a projector in real time to allow observers to watch the team in action from a different room. Will this cut down on the CPU/GPU and other system requirements I would need or is the streaming side of the software not that intensive compared to the processing side?

Thanks for any input, Phule
