How do I turn On/Off motion function on a specific camera(s), set the motion grid and sensitivity on my Paramont DVR/NVR?

Go to Settings, click on Camera, click on Motion on the left. You can toggle motionOn and Off for specific cameras from within this screen, draw a motion grid over the live image for what you would like motion captured in your shot (area with green grid indicates motion activated area) and set the sensitivity you see fit for that Field of View.
