detector.
By default, the detection tool detector is enabled and configured for operation. Depending on the required tasks, you must select a specific type of barcode for detection.
If necessary, you can change the settings of the detection tool detector parameters given in the table:
| Parameter | Value | Description |
|---|---|---|
| Object features | ||
| Record objects tracking | Yes | The metadata of the video stream is recorded to the database by default. To disable the parameter, select the No value |
| No | ||
| Video stream | Main stream | If the camera supports multistreaming, select the stream for which detection is needed |
| Other | ||
| Enable | Yes | The |
| detector is enabled by default. To disable the |
| detector, select |
| the No value | |
| No | |
| Name | Barcode |
| detector | Enter the |
| detector name or leave the default name | ||
| Barcode type | Aztec | Select the type of barcode that will generate |
| events from the detector when detected |

This parameter reduces the load on the Server, but at the same time the detection quality decreases. We recommend enabling this parameter for "blind" (without video image display) Servers on which you want to perform detection.

The Number of frames processed per second and Decode key frames parameters are interrelated. If a local Client isn’t connected to the Server, the following rules work for remote Clients:
If a local Client is connected to the Server, the detection tool will always work according to the set period. After disconnecting the local Client, the above rules will be relevant again. |
| 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 used for decoding |

If By default, the entire frame is a detection area.If necessary, in the preview window, set:
- one or more detection areas
...
- (see Configuring a detection area),
- one or more skip areas (see Configuring a skip area).

The Barcode Detection is configured.
If necessary, you can search for a barcode in the archive. You can search by the text that was recognized during barcode detection (Search by barcode).
