I have a one year old son and after a year of working from home I need to start going to my office from this June. We have decide to keep a nanny but the recent stories about abusive nannies have been lowering our spirits. Me and my husband have decide to keep a security cam at home so that we can monitor how the nanny is taking care of our baby, we also read a blog on it, http://www.calgaryalarm.com/blog/nanny-cam/4-benefits-of-a-nanny-cam/. We are confused whether to use normal CCTV cameras or covert cameras to secretly monitor them. Which would be a better idea? Any suggestions?
