Objects cannot be detected according to their properties
unless the system has been calibrated for the current camera
position (Section 4.3 Calibration, page 21).
Object size filter
Only objects whose size (captured area) is between the
entered limits can lead to the generation of an alarm event.
A person corresponds to around 0.5 m²; a car to
around 4 m².
Objects are not filtered by size.
Object motion filter
Only objects moving at a speed between the entered limits
can lead to the generation of an alarm event.
The speed of a movement crossways to the camera can be
determined much more accurately than the speed of a
movement directly toward or away from the camera.
Objects are not filtered by speed.
Object moves crossways to camera:
speed is detected more accurately
Object moves in camera’s line of sight:
speed is detected less accurately
i
NOTE!
Select generous filter settings for object size and speed so that
all relevant movements lead to an alarm being generated.
