Questions if Zed 2i is Right

I have a few questions regarding the zed 2i stereo camera.

Are each of the cameras individually addressable, or is it a unified video stream? I would like to get each camera individually.

My use case is to have it on a small rc boat. I see that it has an IP66 rating. How well would that do on the water? The goal is not to submerge it, but there is a high probability of getting wet, and always a small risk of being submerged.

My vision system uses gstreamer and deepstream, and I see that there is a gstreamer plugin for the camera. How well does it work? Is it also possible to interact through v4l2?
