The Security Cameras

 The Problem: 

A new Art gallery has circular rooms off a spiral staircase.

The rooms need to be completely supervised by security cameras on the walls.

Obviously, the fewer the cameras needed, the lower the cost and the easier the supervision.

 The gallery manager is currently looking at cameras with an angle of view of 600


Can you advise her on how many cameras will be needed for each room, and how they should be arranged?

Another Security company offers cameras with an angle of view of 800.

Will there be any advantage in using these cameras instead of the previous ones?
