3.1.1 Camera Parameters
To use the VCA zones and rules correctly, the camera needs to be calibrated. This is done
through the camera parameters. The proper positioning of the camera makes sure the
recognition of the object (size, speed) is more accurate
1. Height (meters): how height is the installed camera positioned
2. Tilt Angle (degrees): this angle normally varies between -45° and +45°
3. Vertical FOV (Field of View) (degrees): defines the width angle of the camera lens.
Usual lenses have around 45-50°; a Tele lens has a smaller width, and Wide Angle
lenses can have more.
If you know the absolute numbers of the parameters, you can enter the information manually.
If you do not know the parameters, you can click on the screen with the video on the right side
and follow the onscreen instructions to change the height and tilt angle of the camera:
 Measure or estimate the height of the camera above the ground
