Configuring detectors and their sub-detectors

On the page:

General information

In Axxon One, you can create and configure detectors and their sub-detectors (child detectors). Sub-detectors process the data received from parent detectors.

To create and configure detectors, you must have permissions to do so (see Users).

Attention!

You can create detectors and sub-detectors for enabled and disabled cameras if camera video streams are enabled (see Configuring video stream settings).
You cannot create sub-detectors if the parent detectors don't have the settings applied (you must click the Apply button).

Several identical detectors can operate on the same camera stream:

Detectors	Number of identical detectors for one camera
Motion detector, Neural tracker, Object tracker, Neural counter	10
Water level detector, Queue detector, Visitors сounter, Mask detector VL	Unlimited

Attention!

For other detectors and their sub-detectors, you cannot create identical detectors and their sub-detectors for one camera.

Creating a detector

To create a detector, do the following:

Select the Settings tab → Detectors.
Below the required camera, click Create…. The list of available categories of detectors will be displayed (see General information about detectors and their sub-detectors).
Select a detector.

A window in which you can configure a detector opens:
Click the Apply button.

Creation of a detector is complete. The detector is displayed below the selected camera in the objects tree.

Creating a sub-detector

To create a sub-detector, do the following:

Create the required detector and specify its parameters (see General information about detectors and their sub-detectors).
Below the created detector, click Create…. The list of available sub-detectors is displayed.
Select a sub-detector. A window in which you can configure a sub-detector opens.
Click the Apply button.

Creation of a sub-detector is complete. The sub-detector is displayed below the selected camera and below the detector in the objects tree.

Removing a detector/sub-detector

To remove a detector/sub-detector, do the following:

Select the Settings tab → Detectors.
Below the required camera, select the detector/sub-detector.
Click the Remove button.
Attention!
If you created sub-detectors for the detector, they also will be removed from the existing configuration.
To save the changes, click the Apply button. To cancel the changes, click the Cancel button.

Removing a detector/sub-detector is complete. The removed detector/sub-detector won’t be displayed below the camera in the objects tree.

Bulk creation of detectors/sub-detectors of the same type for different cameras

To bulk create detectors/sub-detectors of the same type for different cameras, do the following:

Create and configure the required detectors/sub-detectors for one camera or select the existing detector/sub-detectors in the objects tree.
Click the button in the lower right corner.
Note
When you select a sub-detector, in the camera list, only those cameras that have the same parent detector will be available.
Set the checkbox next to the required cameras. To quickly select a large number of cameras, press the Shift key, select the first and the last cameras for which you want to create a detector/sub-detector. The checkbox will be set for all selected cameras when you select any of them.
Click the Apply button. The number of cameras for which the detector/sub-detector is created is indicated in brackets.

Bulk creation of detectors/sub-detectors of the same type for different cameras is complete. The detectors/sub-detectors of the selected cameras will be displayed in the objects tree.

Bulk application of settings for detectors/sub-detectors of the same type

For bulk application of settings for detectors/sub-detectors of the same type, do the following:

Change the values of the parameters in the settings of one detectors/sub-detector.
Click the button in the lower right corner.
Set the checkbox next to the required cameras with the same type of the detector/sub-detector. To quickly select a large number of cameras with the same type of the detector/sub-detector, press the Shift key, select the first and the last cameras for which you want to change settings of a detector/sub-detector. The checkbox will be set for all selected cameras with the same type of the detector/sub-detector when you select any of them.

Attention!
You cannot bulk change detection areas (see Configuring a detection area) and skip areas (see Configuring a skip area).
Click the Apply button. The number of cameras with the same type of detector/sub-detector for which the settings are applied is indicated in brackets.

Bulk application of settings for detectors/sub-detectors of the same type is complete. In the settings of the detectors/sub-detectors, the selected cameras will have the same values of the parameters.

Bulk removal of detectors/sub-detectors

To bulk remove detectors/sub-detectors, do the following:

Select the Settings tab → Detectors.
Use the Ctrl key to select the detectors/sub-detectors that you want to delete in the objects tree.
Attention!
You can select detectors of one level only. For example, if you select Motion detector, you cannot select Line crossing and vice versa.
Click the Remove button.
Click the Apply button to save the changes. Click the Cancel button to cancel the changes.

Bulk removal of detectors/sub-detectors is complete. The removed detectors/sub-detectors won’t be displayed in the objects tree.
