Motion Recording vs Motion Alerts

Just installed a new Pro 2, all went well and working my way through settings. I keep going in circles with one setting though, and I wonder if there is a solution.I live in a townhome, with my front door fairly near to the public sidewalk. I don't want a motion notification every time someone walks by, only when they come to my door. However, for security reasons I would like to save video when there is motion on the public sidewalk. I do have the Protect Plan with video storage.I am able to customize my zone and totally ignore the public sidewalk, however I don't want to do that if I don't have to.
