This video footage was captured at a private residence in August of 2016. Using an infrared trail camera, we were able to capture the door opening on it's own, but due to the delay between being triggered and actually recording, we didn't capture what actually opened the door. The house was unoccupied at the time - eliminating the possibility of human interference. All efforts were exhausted in making sure there wasn't a faulty latch or other factors that could have caused it to open naturally. Unfortunately, the camera doesn't record audio.
