We have a stereo problem for which we’d like to use widely separated cameras (50-100 meters between cameras) running simultaneously, plugged into a laptop in some way. We chose gig-e cameras with POE injectors to allow for relatively high bandwidth over large distances; the cameras are each running at nearly the 1G limit and thus we got a dual ethernet-usbc adapter thinking this would allow the cameras to run full tilt while the usb-c would handle the >1G speed into laptop. However upon making this connection we find that we get a ‘not reachable’ status from one camera when trying both cameras at once on different subnets.
This also happens when we set the cameras on the same subnet:
.
This setup works in windows but I would rather not have to deal with porting everything else over to windows. Each camera appears to operate correctly on its own (these are Basler Ace two a2A4200 12gmBAS cameras, and Basler supplies a ‘pylon’ interface which is shown in the 2nd figure above).
We have tried running one camera into the onboard ethernet of the laptop and another into the usb-c adapter and also find only one working camera.
With both cameras into the ethernet-usb adapter the output of lsusb and ifconfig -a are shown here:
