Hi...we happened to have C2 Pro in our site and we immediately tested with wifi environment. It goes good at all with highest resolution, fps, cbr. Then we limited the network bandwidth of camera, we observered that the camera view was significantly delayed or blocked, which was not the condition of the bottom 25% of the live view heavily distorted. Thus it is odd that we guess it might be relevent to your wifi network environment. How about decreasing resolution / fps for the one with wifi? Does it work for that?
