I am expecting a baby in a few weeks time. Mom will be home for at least 3 months maternity leave after which the baby will be looked after by our helper. She has been with us for a few years now but with all the horror stories out there about monstrous nannies that neglect the child, sometimes assault or even kill the babies I think it is safer to at least invest on some indoor surveillance system. I need some suggestions on a simple and cost effective system to do indoor surveillance.
