The Security Cameras
new Art gallery has circular rooms off a spiral staircase.
rooms need to be completely supervised by security cameras on the walls.
the fewer the cameras needed, the lower the cost and the easier the supervision.
gallery manager is currently looking at cameras with an angle of view of 600.
you advise her on how many cameras will be needed for each room, and how they
should be arranged?
Security company offers cameras with an angle of view of 800.
there be any advantage in using these cameras instead of the previous ones?
