Even when the lights go off in a cinema hall, you can still be seen on camera—most theatres use infrared (IR) night-vision cameras.
IR light is invisible to the human eye, but cameras capture it clearly.
In complete darkness, the camera switches to night mode and records everything in black and white.
So no matter how dark it gets, the camera sees everything inside the theatre. 🎥
