My concerns with a webcam is that it allows the parent to see things in isolation and out of context and does not truly reflect the whole day.

Besides that the parent is supposed to be working and doing anything that promotes them not giving their best at work means they run the risk of being fired and not needing care.

Another issue for me is equity - not everyone is an executive sitting in an office with free use of computer - many are in the factories, hospital wards and grocery store and not able to use the service anyways.

I dont' like that it takes away from the child because the parent that was "spying" on their child is bound to try and use that information to make conversation with the child that night or to drill them on why they weren't part of the fort making group or why.... and the child can't remember the details of the day and spoils any fun they had.
