[How can I tell when someone is camming over me?]

Hi everyone,

So I recently came to the understanding that there is a setting (or something) that allows you to see where other people are looking or when they are camming over you. How do I do this? I have the Firestorm viewer and would very much so like to know. :)

Also, the person who told me this said he could see who specifically was looking at him... Please explain to me how this works and how I can do this as well! 

Thank you, all!
