When i leave for long periods at work. I have to step away from my computer. And to be honest I don't trust anybody in my office. Is there an app for like that iphone that I can use to connect to my laptop at work to monitor the isight and listen into the mic without the green light going off? I would love to know if such an app exists or if theres a possible way to do this w/o people know my laptop is in surveillance mode. I know theres a security screen saver, but i'm looking for something more.
