5 Nights with Noob in Prison

You'll experience five nights playing guard at the Dangerous Criminals Prison, the place where Noob is taken into custody!
You have an ordinary phone at your disposal, on which you can view cameras, read messages and answer calls.
Be very attentive and keep your eyes open to prevent Noob from catching you. The main Monster doesn't doze off, but he's very afraid of bright flashes. Noob likes to scare the guards by calling them on the phone.
Can you make it through five nights?
