# OPSEC: disabling video/audio input on a mobile

**For back facing cameras**: 3 layers of non-fabric backed silver-grey duct tape. On mine this can be over the rear cover.

**For front facing cameras**: 1 or maybe 2. The main difference might just be it's easier to seal all lateral light on the smaller one.

**For the microphone**: install a voice recorder, usually when they are recording they have some indication of input volume. The mic should be a little hole down the bottom, usually on the edge of the phone, though in the olden days it could sometimes be integral with the case in the bezel. One fully sealed tiny bit of this magic silver tape and it's silenced. (sorry, what? can you hear me? Oh, i forgot about that. Good *click*).
