Hi~ I has more than three cameras need to capture. I can capture one camera by setting static ip in both network card port/camera, but I have no idea how to capture other camera by pylon_camera. Or is there has other ros package can do this?

(update) Setting camera ID can let pyloncmaera capture specific camera, but it still can't capture multiple cameras. Both camera is capture by pyloncamera_node, but using same node name and topic name, then first camera will be shoutdown. Anybody has solution for this case?

I testing result is shown in below:

first camera

brightness is given and has value 100
