False counts
|
Shadows

Shadows can generate false counts, for example, sunlight from outside, occasionally obscured by moving clouds will cause shadows to cross a counting line. Depending on the angle of an indoor light or the sun, the shadows of people walking by (but not crossing) a counting line can trigger false counts.
|
|
Incorrect camera placement. In this example, the opening and closing of the door may cause false counts.
|
How to tell if you have set the camera height correctly: The Person Size box should be no more than 1/3 the size of the screen and no less than 1/5 of the size of the screen.
|
|
Incorrect counting line placement. For example, this counting line is too close to the door.
|
In general, it is better to put the counting line further away from the door, so that people do not stop on the counting line.
