All electronic devices effect beacons. The proximity to your beacon seems to be the real issue. That is why the one foot rule in proximity to your beacon has been brought up. Seems that the range interference is minimized by that distance. Which if you are wearing the cam on your head should be more than enough. Everyone needs to make their own decision, but I am still rocking a helmet cam. Chesty mounts are probably not a good idea of course. I also need to make sure I turn my DSLR off when I am not using it, since it rides on my chest.
