Perspective Settings
Select Overhead Camera if the camera view is pointed straight down. Select Perspective Camera if the camera is at an
angle. Set the person size box carefully; the accuracy of the person size box will directly affect the accuracy of ana-
lytics rules.
Overhead Camera
Overhead Camera’s are ideal for Video Analytics. Adjust the person size box to show the average size of a person. The
analytics engine uses the person size box when it is deciding if an object is a person or a vehicle. Car size is auto-
matically determined relative to the person size.
Perspective Camera
The person size will increase as the person approaches the camera. Move and adjust the first person size box to show
the size and location of a person farthest from the camera. Move and adjust the second person size box to show the
size and location of a person closest to the camera. The analytics engine uses the relative person size boxes when it is
deciding if an object is a person or a vehicle. Car size is automatically determined relative to the person size.
