White round object comes under front door and flies thru living room (on video).On the morning of Saturday December 10, 2016, at 07:12 AM, my wife’s phone received an alert that the living room security camera had pick up motion. We were still in the bedroom. My wife and I are the only people living in the home, so I assume our dog must have set it off. ((dog's name deleted)) (the dog) is gated off from the living room, but I thought we might have left the gate open inadvertently.I checked the event recordings and saw a white round something come under the front door, fly in a non straight line through the living room and past the camera. I do not know what it was. The dog gate was closed, doors locked and deadbolted.I have saved the video of the event.
