Will the classroom spherical camera light up when it is on?

The light is on. There is no doubt that the camera must be on.

the light is off, it may be on or not. When the camera is not on, the light is definitely not on, and there is no doubt about this.

When the problem camera is on, the light doesn't turn on, because the light in the classroom is strong, and there is a photoelectric sensor on the camera, which senses that the light is sufficient and there is no need for auxiliary lighting, so the automatic control circuit turns off the lighting.
