you dont see many cams around due to the enforcement against in theatre camming.
even teleciene versions are few in number [a way of camming in your pirate loPHt]. it seems cams were a counting coup for scene credit and its now just looked at as dangerous.
actual copying of prerelease screeners is in the mire as well. screeners basically were watermarked and sent out as promotionals so a theatre location could judge if they wanted to show them or not, and as promos in store to encourage rentals.
telesync uses an audio channel, telecine is just video and uses an electronic photomultiplier array as a sensor to convert the light of each frame on acetate to a bitfield frame, its not a camera but done properly it can be high quality. its not a cam its more like scanning each frame of film. the thing is about 20 years ago there was a lot of cams and TKs and TSs, now that streaming is the thing its not very common to see these and you know they are very old compared to the usual transcoding and wrapping nowadays
