To configure the Object tracker detection tooldetector, do the following:
- Go to the Detection ToolsDetectors tab.
Below the required camera, click Create… → Category: Trackers → Object tracker.
By default, the detection tool detector is enabled and set to detect moving objects in the frame, on the basis of which their tracks are created.
Some parameters are set for all sub-tools detectors of the Object tracker simultaneously (see Recommendations for configuring the Object tracker and its sub-detectors).
If necessary, you can change the detection tool detector parameters. The list of parameters is given in the table:
| Parameter | Value | Description | |||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Object features | |||||||||||||||||||||
| Record objects tracking | Yes | By default, metadata are is recorded into the database. To disable metadata recording, select the No value.
| |||||||||||||||||||
| No | |||||||||||||||||||||
| Video stream | Main stream | If the camera supports multistreaming, select the stream for which detection is needed. Selecting a low-quality video stream allows you to reduce the Server server load.
| |||||||||||||||||||
| Other | |||||||||||||||||||||
| Enable | Yes | By default, the parameter is enabled. To disable, select the No value | |||||||||||||||||||
| No | |||||||||||||||||||||
| Name | Object tracker | Enter the detection tool detector name or leave the default name | |||||||||||||||||||
| Decoder mode | Auto | Select a processing resource for decoding video streams. When you select a GPU, a stand-alone graphics card takes priority (when decoding with Nvidia NVDEC chips). If there is no appropriate GPU, the decoding will use the Intel Quick Sync Video technology. Otherwise, CPU resources will be are used for decoding | |||||||||||||||||||

| Type | Object tracker | Name of the detection tool detector type (non-editable field) | |||||||||||||||||||
| Neural network filter | |||||||||||||||||||||
| Enable filter | Yes | By default, the neural network filter is disabled. To enable a neural network filter to filter out parts of tracks, set the value to Yes (see Hardware requirements for neural analytics operation). For example, a neural network filter can process the results of the tracker and filter out false positives on a complex video image (foliage, glare, etc.and so on).

| No | |||||||||||||||||||||
| Moving object filter mode | CPU | Select the processor for the neural network operation (seeHardware requirements for neural analytics operation, Selecting Nvidia GPU when configuring detectors).
