Missing
Object Size Error
Range
Sets the minimum and maximum variation to the person size set in the Perspective Settings.
Light Change
Threshold
Allows light changes to occur within the image without triggering any false objects to appear within the image.
For example lights turning on or off.
Max Analyze FPS
Adjusts the maximum number of frames per second that will be used for analysis. If this value is increased,
more CPU load will be required for the analytics engine.
If objects are moving very quickly through the image in a narrow field of view then this value can be increased
to detect objects more accurately. If objects are moving very slowly through the image in a wide angle view
then this value can be decreased to reduce CPU load.
Two Pass Object
Count
Allows more comparison with past frames to provide a more in-depth analysis using logical deductions in views
with perspective.
Strict size esti-
mation
Puts more emphasis on the size of an object and less emphasis on its behaviour to determine if it is a valid per-
son or vehicle.
Count by Trace
Objects must be travelling through the image and move valid distance
Objects must be travelling through the image at a valid speed
Average size of the object must be consistent as it moves through the image
