I work for an IT company but we do not really deal with camera systems. One of our clients has a camera system that uses a Hikvision iVMS-4200. When viewing the cameras and playback on a computer, it hogs all of the PC's CPU. I have seen this in the past with another client that has the same system. There was a setting that allowed you to change the decoding process from the local system to the NVR itself. I noted what I did when I discovered that, but for some reason I did not note how I did it. Can anyone help me out here? I remember it was a simple drop down box.
