Where are they aimed??
What is to prevent unscrupulous store owners and/or software authors from analyzing camera data gleaned from cameras aimed (for instance) at men's and ladies room doors. They can then determine if a particular shopper is spending too much time in the john and target them for laxatives, diuretics, toilet paper, etc How about cameras aimed at the sanitary napkin aisle, or the condom shelves? That might make a few shoppers a bit queasy!!
What we need is a clever hardware engineer to come up with a camera-jamming device, just like the one that now can be used to remotely change a TV channel, turn down the audio, or turn it off!
