I know you probably aren't interested in taking suggestions, but here is an idea:
Phantom Animatronics: They either A.randomly show up on the cameras and force the player to change to another or pull it down, B.appear in either door blindspot, and if the player sees them in the light, quickly turn off the door light, or C.appear directly in the office, making the player have to pull up the camera to avoid them.
If the player fails to do any of these, they will jumpscare the player and temporarily make the cameras unusable.
