There's a security camera in the elevator in Cyberlife Tower that can be spotted by Connor, but one can also play without doing anything about it. If Connor hacks the camera before attacking the others in the elevator, he won't have to fight guards when he exits the elevator, because they didn't see him acting deviant. Hacking the camera takes the player to the camera's POV and shows its vision flickering and shutting down. Note that if Connor doesn't fight the guards in the elevator, he will be "terminated" when the doors open. This Situation is for Connor hacking the camera.
