• Enter the Camera Height.
If the camera height is known, then it can be entered. If the height in not known then it is recommended
to obtain an accurate reading otherwise estimate it based on known object heights in the scene.
Note
: A correct camera height measurement is required for accurate video analytics
• Enter the Cameras Tilt Angle.
If the tilt angle of the camera is known, then it can be entered. If the tilt angle is not known then
estimate it and use the mimics as a guide to confirm and change as required.
• Verify and change as required.
The objective is to ensure the mimics match people or other known objects in the scene, both the
height and angle of the mimic should represent the objects in the scene and adjustment of the height,
tilt and vertical field-of-view may be required to achieve this.
