Nevermind, I figured it out! Just wasn't clear to me that there is a "hack point" above the door, maybe you can put a terminal there...
yeah sure, sorry ,the game has 2 part, the second part is a labo where there is traps.
i realize know that its not clear hhh, the first part you cant dash to pase tha camera,cause the guard will hear you,then you hack the camera,
the guard will open the dore and get out to check, then you hack all camera by hacking pc, after that, you take the lader, yoy try to take the key where the guardien is patroling, the key is not clear sorry,its behind the bed,after that, you can go to the lab to descovere the item that you shoud steel
