Im thinking about building a ROV that is controlled through a cat5 cable.
The ROV will be sending video signals through the cable, while the computer is going to send signals that activate motors.
I know there are ip-cameras that sends video through ethernet cables
and I know that a cat5 cable consists of 4 twisted pairs.
So does an ip-camera send signals through 1, 2, 3 or 4 twisted pairs?
That means that controller signals can go through the other pairs.
And how would I code computer inputs into signals and then let the ROV decode them into motor activations? Guidance and links are appreciated
