you have to collect 3 fuses, then use them at the fuse box in the room next to the security office. Then, you can unlock the door using the computer int the office.
I can't seem to unlock any tapes, even using methods from other commenters. the one tape I can get is the one you get from collecting the tapes on the cameras, but it also won't play when I try to watch it. anyone else?
Edit: I should clarify: when I try to play the tape I have, the video is frozen on whatever frame of the into was last played.
