I was using this ROS node https://github.com/UbiquityRobotics/raspicam_node but the latency increased with the time? Why is like that and what approach is using that node for the image compressing? Does is compress frame by frame?

Guido Ehrmann

what happens if you reduce the resolution of the recorded video. This should reduce the latency. I don't know if this would be suitable for you, but would be a good test, if the overall performance will grow.
