General Information about Tag&Track Pro
Tag&Track Pro is a feature for automatic tracking of moving objects using a PTZ camera based on tracking data received from static overview cameras. The system uses one or more overview cameras to detect and track objects. Based on the object's coordinates calculated by the overview camera, the system determines the target and automatically directs the PTZ camera for detailed tracking. The PTZ camera is positioned so that the tracked object is always centered in the frame.
This feature requires the combined use of at least one overview camera and one PTZ camera. An unlimited number of overview cameras can be connected to a single PTZ cameraTag&Track functionality depends on the PTZ mode that is specified in the settings.

If automatic mode is selected, the PTZ camera will track all active objects. In this case the PTZ camera switches focus between each object with the specified dwell time.

If the PTZ camera is in manual mode, the user controls it with on screen or with a joystick / CCTV keyboard. If the user does not operate the PTZ camera (The PTZ Control Panel hidden), then the Automatic mode is used.

System configuration for Tag&Track
To use Tag&Track Pro, do the following:
- Arrange cameras so that their fields of view are directed downwards onto the surface (floor, ground) on which objects are moving. This ensures stable and accurate tracking.
- Direct the overview and PTZ cameras that you use in the same direction and position them close to each other. If you position the cameras too far apart from each other, it can lead to different interpretations of the scene and failures in the algorithm operation.
- For all objects from the overview camera, the corresponding pan coordinates (rotation of the camera left and right without change in its position) must be in the range from 0° to 180° or from -180° to 0°.
- For each of these cameras, configure the detector: Object tracker, Neural tracker, Human tracker VL, or Motion detector. You cannot use other detectors. The operation of this feature requires metadata (see Metadata database).
Note title Attention! For Tag&Track Pro to work on the basis of the Motion detector, in the Object tracking parameter of the detector, select the Yes value (see Configuring the Motion detector).
Enable Object tracking in the surveillance window of each selected camera on the layout.
- Connect overview cameras to the PTZ camera and configure calibration (see PTZ).
- Select the control mode of the PTZ camera in the Priority parameter and, if necessary, set the duration of the camera focus on one object in the Switch Frequency parameter (see PTZ).
Using Tag&Track Pro
You can use Tag&Track Pro depending on the control mode of the PTZ camera that you select in the Priority parameter (see PTZ).
Joint operation of Tag&Track Lite and Tag&Track Pro
In some situations, Tag&Track Pro and Tag&Track Lite (see Tag&Track Lite) can run simultaneously.
For example:
You set Tag&Track Pro to Manual mode or User priority mode in the Priority parameter (see PTZ);
You select an object for Tag&Track Lite in the field of view of a camera that is added as an overview camera for Tag&Track Pro (see PTZ).
In this case, both Tag&Track Pro and Tag&Track Lite are enabled, and the following occurs simultaneously:
PTZ camera tracks an object;
the system calculates the camera in the field of view of which the selected object can appear
