Not knowing much about video jamming, is it possible to block this hack by attacking the cameras?

  I read a paper on such a technique a while back. The CMOS sensors in smartphones are very sensitive to a certain band of infrared. I think it would be possible to set up a system that automatically detects smartphone location and splashes its general area with infrared. With a good controller and motor setup, you could probably have a single jammer that can alternate between multiple phones.

    And can be blocked with a small piece of infrared filter film.

      It depends on the threat model I guess. Whether or not such a system would work in a casino environment, I don't know.
