It's simple really if you have enough sneak(or the obfuscate skill above lvl 2).
You sneak in, plant the cameras, no one sees you.
Walk to her computer, use the net command and password (cleopatra if Im not mistaken). Use the command for starting/detecting the cameras and Voila, done and done.
By the way, make sure NO ONE sees you when your sneaking out, the quest will fail that way and you will NOT be notified of that until you speak with the chick in the warrens...
Good luck
