I hope this hasn't been asked before. I looked, but didn't find it on search. I'm at the 2 mission. There's a part where I have to go out onto the balcony. I've been to the basement parking garage and interrogated the driver. I've made my way up to the office, then to the balcony. I get out there(it faces the courtyard that has a laser grid system). I'm supoossed to "shimmy" across what looks to be a rain gutter thing over to an open window. The problem is that as soonas i get a certain distance, an alarm goes off. I've searched and I don't see a camera. I don't see anybody in the yard or in another window. What am I doing wrong? I hope that explanation was clear enough.
