When playing alerts I am getting rectangles on the motion that I do not want. If I look at the camera trigger settings the Highlight option is set to "Do not highlight motion". How do I shut off these motion rectangles. I have not seen any place other than the trigger settings that relates to this.

I think you have already turned them off correctly in BI5. Could they from the camera itself ? Have a look at the video directly from the camera in a browser.

During playback, right click on the video -> Overlays -> Add motion overlays -> Uncheck
