The first light anomaly. In this video a round light object appears in frame 5 in the upper right corner of the frame at the door and stays for a second and then disappears. There were no investigators around this camera at the time of the anomaly so it couldn't have been a reflection of any kind.

This a 45 second video. What is happening here is that in frame 2 the back banister leading up to the rear doorway into the house begins to inexplicably light up. It varies from light to dark for about 40 seconds. The only light on the back of the house was the outside light on the house which is illuminating the door. There are 2 investigators in the house at the time. One is lying on the couch in frame 7 and the other investigator is sitting in a chair to the left of the camera in frame 7. The other investigators had gone to get coffee and were no where near the house at the time. There are nothing but woods behind the house and no roads go behind the house.
