Latency with Ethernet connection Studio Camera 4kg2 to ATEM

Hello, my tests are not conclusive: with a Studio Camera 4k G2, in Live Streaming mode to the ATEM TVX HD8 ISO, after opening an Ethernet channel and connecting the camera and the mixer in RJ45, and entering the "identification key", I receive the signal from the camera but the latency is almost a second!! Did I miss something? How can we not have such latency?
I tried to modify the different encoding qualities but nothing helps.
Thanks
