Whoever implemented the surveillance of children should burn in hell. Since that probably doesn't exist the next prison with strong similarities should be chosen. You teach them that this kind of 24/7 surveillance is normal and I think they have enough problems with peer pressure through social media. You also teach a zero trust behavior. That can be good in a context and it can be really bad if it becomes learned cynicism.
I could understand it until age 10 perhaps but at some point you want your kids to be independent. If they aren't bots by that age.
