UPDATE: Camera stalling now works a better explination, close the right door whenever freddy laughs (meaning he goes to the door) then when he laughs again that means that he's gone and you can open the door. close the door if someone is at the door and if you hear foxy running close the left door (you have enough time to move over and close just remember where the lever is) bewere of bonnie in the left door because he can sometimes just like be invisible and not show even when you flash the light an kill you stay on cam 4b to check if freddy is there incase you lose track of the laughs
camera stalling is when you look at an animatronic through the camera, making it so they cant move. this only works on some animatronics though and you have to look at them in a certain amount of time. freddy being every 3 seconds. if you don't look at freddy in the right corner camera every 3 seconds then he will jumpscare you.
