For the precise tracking of moving objectsthe object under observation, you must calibrate PTZ cameras by mapping at least six PTZ positions to points in the field of view of each panoramic camera.
The more positions you map, the more precisely the PTZ camera is able to follow moving objects. It is recommended to map eight or more points.
...
should calibrate the telemetry device by matching at least four telemetry device positions with the frame points of each overview camera.

The recommended number of points that should be set is 4-10. If you add more points, the algorithm will be configured more accurately. However, this will increase the chance of introducing a wrongly set point into the calibration algorithm, which can lead to an overall deterioration of the operation quality. The points set in the calibration setting should not be on the same line for both the overview and the PTZ camera. It is recommended to set the points for both cameras so that they evenly cover the entire frame. The calibration points should be set on the same surface (floor, ground). It is not recommended to set the points on different surfaces (for example, when some points are on the ground, and other points are on a tree, etc.). |
To calibrate the telemetry device, do the following:
- Select the overview camera from the list (see Linking panoramic cameras to a PTZ camera).
- Focus the PTZ camera on any point.

Calibration of the telemetry device is complete.
It is recommended to After setup is complete, we recommend that you perform a calibration check after calibration is complete. To do this, do the following:
- Click the
button to the right of the preview for that PTZ window of the overview camera. Click on different points in the
camera's field of viewimage of the overview camera. If the PTZ camera is positioned correctly,
