To confirm the problem you are having - whenever there is motion in front of your camera you see a pixelated video. This can usually be fixed by matching the frame rate and bandwidth to what you have available on your remote and local network. It looks like the camera is located at a remote warehouse, and you are monitoring it from your DSL or cable connection at your home.
I logged in to your camera and I saw that the frame rate and the bandwidth settings on the camera was too high. I adjusted the settings of your camera to match it more accurately with the network bandwidth. The frame rate was reduced from 15 to 7.5 fps. The bandwidth reduced from 1mbps to 512kbps. I have tested from my office, and the recordings now appear very clear at all time, including when there is motion.
