   No, special shielding kits for the studio (and film) cameras {when they
were still in use} are necessary when AM towers (5kW for sure) are in sight.
Additionally ferrite (or powered iron) cores are required on audio and video
cables go to and from the main building and the MW shack at the base of the
STL tower, if any.  Interference in audio or video equipment must be handled
on a case by case basis.  Leaving the cover off of some things can have a
regrettable effect.  For these reason I don't want an AM transmitter within
5 miles of my TV transmitter plant.  TV remotes close to AM transmitters just
don't work because you do not have shielded cameras etc, tried that once.
