The 2F Surveillance Room Report is a memo found in the Water Prison that Henry Townshend can collect; it serves as a clue on how to solve a specific puzzle. It is found on the desk in the second floor surveillance room.
To keep a close eye on the kids, it's important to keep the cells well lit.
The lights on the 3rd floor were originally bought as searchlights.
As a precaution against a blackout, they were set up to run on a private
generator. There's a hydroelectric generator in the basement. To light up
the 1st and 2nd floors, use the corpse disposal chutes.
Since each floor of this building can be rotated, you can light up any of the
cells by matching up the holes. Repeating this periodically is an
effective way to keep the kids fearful and well-behaved.
Chief, if you turn the handle in the middle of this room, you can easily
rotate the cells. You can't rotate the 1st floor, so align the 2nd and 3rd floors
with the 1st floor cell that has the blood-stained bed.
By the way, if you use the peephole in this room, it's easy to make sure you're
doing it right. Give it a try. Also, please don't forget to open the
sluice gate on the roof.
Much appreciated, Chief!
I want to go home.
