@sena_K,

If you are using a low resolution analog video camera, then the [Fathom S](https://www.bluerobotics.com/store/electronics/fathom-s-r1/) interface will work.

If you are using a high resolution USB or RPi video camera, then you will need the Fathom X interface and a RPi and any required support hardware.

You can use a normal ethernet cable. You do not need an interface board for a short length (\< 100m) of ethernet cable.

Actually, I’m worried about video transfer. Because we need live video to move on. Then there will be no problem?
