I will be deploying soon and I am hiring a nanny to help out my spouse with our son while I'm gone and he is at work. I just want to be able to check in on my son while I am overseas via the Internet. Just to make sure he is being well taken care of and for my husband and my own peace of mind. I was searching into different surveillance and decided to get a wireless IP security camera system. The problem now is that I understand the wireless part but don't understand how I would be able to check in on him while so far away? We do have wifi in our home. And a main part is I don't know which Wireless IP security cameras would best work for us? Please help?
