The answer to your problem is called the Rolling Shutter Effect.
You can simply make ALLl the lights in the cabin strobe at a frequency close to the rolling shutter speed of the cameras most people have. Or at 2, 3, 4, or more times that speed.
Much like old TVs digital cameras take pictures in strips. by picking the right frequency you can cause bands of lightness and darkness in the image, ruining the photo.
You can then choose a camera which is less or not susceptible or synced with the strobe effect to mitigate its effects.
The strobe would be rapid enough to go unnoticed by the human eye and really mess with electronic cameras.
But there are cameras that some people have that may not be effected by it, but most cameras have some issues with it, so your mileage will vary
You are always doing something marginal when the boss drops by your desk.
