Stage Lights Operating by Themselves

On Thursday November 14th at @ 8:23p, the light behind the stage curtain goes off. At the same time, the camera behind stage goes dark and continues to record briefly and then stops.
The light comes back on at @ 8:46 and the new camera starts recording again (not shown).

The light is operated by a physical switch in that area. All other cameras were checked and no one was in the building. If someone had entered through the back door, the panic light would have come on and that does not appear. The stage light was on from about 2pm and stayed on until this occurred.

The clip on the left shows the light going off and later coming on from the auditorium view (watch the “seconds” counter of the clock) and the clip on the right shows the stage camera going off at roughly the same time. As mentioned above, the stage camera starts recording a few seconds later on it’s own, but that was not included here.
