Capturing 6 FullHD streams with Jetson TK1

Hi all,

I’ve asked this question in another similar thread but I think it’s better to give the question it’s own.
What I want to do is connect 6 cameras to the Jetson board and capture the signals with an application.

I’m new to all this, it’s my first board, but I’ve got some time to figure things out and I do have programming experience.

What would be the best way to connect the camera’s?
GigE Vision cameras are pretty expensive.

I was thinking of using the CSI 4x1, but I’ve learned that it’s only capable of managing 4 camera’s tops. Is this right?
The other camera’s could be connected via USB ports though.

Any other options you guys can suggest?

Thanks!
