I received an alert that there was a human at the door. I watched the video and no one was there. There is a car driving by (too far away to set the camera off). I’m at work, so I asked my wife what the loud popping sound was. She didn’t hear it and she’s on the couch 3 feet from the doorbell. She said she just looked at the doorbell camera live and got the same popping noise. It’s never happened before. #aifail
