Today the UPS truck pulled up in front of my house, the man got out and delivered a pkg next door. but the ring only recorded the man getting back inside his truck and driving off. why didnt it pick up the motion of pulling up in front of my house ? . it always records cars driving past my house, or people walking past the house . but today it did not record the UPS man until he was leaving, there was plenty of motion when he out and right in front of my front yard/door/doorbell.
