Japan has had this pretty widely available for years. And it hasn't been used for pedophilia as far as I have heard, unlike say cell phone cameras, which now all make an unmutable sound when you take a picture.
The reason? Silent cell phone cameras are great for taking upskirt pictures on crowded trains, and the internet exploded with upskirts soon after cell cameras became popular here.
Back on topic, the tracking and limits are a tool for parents, not a replacement for parenting. Why is it a tool, not a replacement? Well, if you don't look at where your kids are, this new cell doesn't do much. It's not a border enforcing shock-treatment item (yet).
