I think Salesa's camera affords protection against all the powers but VERY SPECIFICALLY wards off the Eye. So other things like Annabelle and the Corruption monster Salesa mentioned can still benefit from their patrons but Jon is cut off from his.

ohhhh yeah that would make sense, especially considering that I’m pretty sure the camera was described as being broken back in the ep where Salesa first got it which is, now that im thinking about it, pretty clear symbolism for vision not working. Thanks!!
