Television producer, Stella Hall was in bed in Tempe, Arizona when she was alerted that her domestic camera began recorded at 1am due to the movement being detected.
The clip shows the front door to the apartment with windows surrounding the door and light shining into the residence.
The camera detected movement and captured a mysterious shadow floating in front of the door but there is clearly no figure that could have cast said shadow.
People have been labelling the incident as an act of the paranormal as there is no clear explanation as to what the shadow might have been.
Stella said: “I was pretty creeped out.
“I wasn’t sure if it was a person or not, so I made sure that the house was secure and locked all the doors, just in case.
“I do believe in the paranormal but I try not to jump to the conclusion that there’s paranormal activity whenever strange occurrences happen.
“Then I watched the video a bunch of times to try figuring out what caused the shadow.
“That usually works, but sometimes there are situations that can’t really be explained, such as in this video.”
