I work thirds shift as a security. I was at a location in a small town for about two months. There was a main building, and small guard building outside of it where everyone had to do through to get the other building.
My nights consisted of watching the CCTV monitors, and on nights when no one else was there i would patrol the outside area and inside of the building. One night i was looking through the camera footage as it played live, and i saw an orb appear on camera outside the side of the guard building.
