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.
