In this particular book, that angle is more of a minor plot thread. Those politicians who don't buy into using the necklace 'body cam' version of this tiny camera to become transparent (to become 'clear') to their 'constituents' begin to become ostracized or, worse, blackmailed and then jailed (e.g. ostracized). The plot does revolve around people judging the central character's every action in real-time through these tiny cameras.

'1984' is more along the lines of not being able to hide with the 'TV' that watches you while you watch it.
