6.What problems are you experiencing?

I am building a set up where I need to run 6 cameras simultaneously, with a minimum of frame drop. I know that I can use a multi-cam adapter for up to 4 cameras, but is it possible to run 3 cameras off 2 Raspberry Pi boards and stream them straight to the laptop. Also, the camera set up is outdoors with a maximum distance of 500m and the laptop is stationed back in the office. Is this possible?
