How to you set range for 4 cameras? – TapCMS1.01 Review

I have tried setting the range for my four cameras to the maximum for event motion detection but even when I saved there is no change. My cameras are not recording any events on one of my cameras and barely captures motion on the others. I can’t find any instructions on how to reset motion detection for this app. Please help!
