What laptop would be best for video conferencing through a wi-fi connection?

I am looking for a laptop that I can take on a deployment with me. From what I understand, there will be a hardened shelter that has a wi-fi signal available to us. I would like to get a laptop that has a (preferably) built-in video camera that enables me to connect with my wife and kids for video conferencing. I have never owned a laptop and have only ever worked with desktops so my knowledge of laptops is extremely limited. Please help me out! Thanks a million!!!
