Horizontal Field of View
From X10Wiki
Our Camera has a field of vision in the same sense that you and I do. The horizontal field of view refers to how far it can look left and right without physically moving, similar to the way you can scan a room with your eyes without moving your head. The field of view is 50 degrees when stationary. The camera is able to pan 180 degrees left to right. Combine everything, and the total horizontal viewing area of 230 degrees.
