I have installed web cam/ survailance systems for business customers so that they can check on employees at work over the internet, it is called VPN tunneling. I have also seen the same application for daycares whereby parents can check on their children over the internet simply by logging into their respective accounts, and clicking the check on my child icons. Pretty cool, but really expensive as one would have to purchace the equipment, then the static IP address on a wide area network (WAN), from a service provider, then pay someone to set up a vpn, and the software to run the operation, but it is cool once you have it in place.
