I just noticed (didn't notice this before with my older 5216 NVR) that when in LIVE view in the NVR looking at a camera, wherever I click in the live view, a yellow dot just appears.. if I click in a different spot in the view, the yellow dot moves there.. Any idea what this is?
is it something to do with digital zoom? I.e. click where you want the center of the zoom area to be and then use your scroll wheel on your mouse to zoom in?
