If you are given a laptop with a camera on it by anyone it is possible for them to watch you. Like the Mommy cams etc. My webcam lens is as big as a pea and a little piece of tape will stop anyone seeing through it. Of course I bought my own laptop and didn't rely on others to get me one so I am not worried about anyone accessing it. There has to be software installed and you have to open up a firewall port and get a Dynamic Domain Name System subscription for a user-friendly IP address to access any webcam.
I guess a hacker could do it w/o me knowing it but why would they? LOL
