Table 5. Advanced Options - Object line crossing duration
Option Description
Default
Setting
Object line
crossing duration
(seconds, 1 to 10)
Defines the object length in the time dimension: the time it
takes for an object to cross the line.
• Increase this number if one person is counted as two
back-to-back people.
• Decrease this number if two back-to-back people are
counted as one person.
1.00
Multiple object
support in length
(consecutive)
Used in cases where more than one person can be crossing the
line, that is, people following each other in tandem, with little
gap in between individuals. This feature prevents the video
engine from counting a group as one person.
If the option is off (unselected), then a group of people will be
counted as one person.
Also, if the option is off (unselected), the value in the
Max
Object Length Ratio
option becomes irrelevant.
On
Min object length
ratio
The ratio of time (with respect to
Object line crossing
duration
) that is required to detect an object. For example,
assuming 10 FPS analysis rate, enough motion must be
detected in at least 2 consecutive frames in order to count a
person (as well as in at least 4 pixels width).
• Increase this number if one person walking at regular speed
is counted as two people.
• Decrease this number if people are walking very quickly and
no one is counted.
0.50
Max object length
ratio
The ratio of time (with respect to Object line crossing
duration
) that is required to consider that a new object is
coming behind without any gap.
Example: If people are walking with strollers/shopping carts,
try a ratio of 2.5 so that the stroller/cart is not counted as
another person.
• Increase this number if one person is counted as two
back-to-back people.
• Decrease this number if two back-to-back people are
counted as one person.
