The ONVIF-Server module supports filtering of messages and events transmitted in the metadata stream according to the ONVIF standard: Topic Filter and Message Content Filter.
You can configure the correspondence of messages for Topic Filter and the Axxon PSIM events. These are the ONVIF-Server events that start with tns and tmk in the examples below on this page. Axxon PSIM will transmit only those events for which the correspondence is configured. The remaining events and messages are sent automatically according to the specification (for example, when changing the server, profile or MotionAlarm settings, etc.).
The correspondence of messages for Topic Filter and the Axxon PSIM events is configured in the following order:
- Go to the Event settings tab on the settings panel of the ONVIF-Server object.
From the drop-down list of the ONVIF-server event column, select the ONVIF-Server event (1). See the events description in the table at the bottom of the page.
Note
To add a row to the table, press the "down" button on the keyboard; to delete a row, use the Ctrl+Del keyboard shortcut.
- In the Computer, Type and Number columns specify the parameters of the object, from which the corresponding event comes (2). The Name field will be filled in automatically when you left-click it. If any column parameter is empty, it means that the message will be sent for any value of the corresponding parameter.
- From the Event drop-down list, select an event which comes from the selected object and corresponds to the specified ONVIF-Server message (3).
- If the specification requires that the event should contain certain parameters (see the table at the bottom of the page), it is necessary to specify their values or the correspondence to the Axxon PSIM event parameters in the Transfer parameters table:
- The ONVIF-event parameter name column contains the required parameters of the ONVIF-Server event (4). They are set according to the specification.
In the Event parameter name column, it is necessary to specify the parameter value or the Axxon PSIM event parameter names (5). Event parameters can be found in the Debug window, and some of them are described in the Description of events and reactions of system objects section (see Guide for creating scripts (programming) ).
- Repeat steps 2-5 for all required events.
- Click the Apply button (6).
You can check the message and event filtering in the third-party software, for example, in the ONVIF Device Manager utility.
To do this, go to the Events or Metadata page, depending on what messages you want to see, set the filtering conditions (1) that will be displayed in the list (2), and then click Apply (3). As a result, only the events that match the filter should be displayed.
Examples of filters used in the ONVIF Device Manager utility:
- Topic Filter
- tns1:VideoSurveillanceSystem//.
Events where the topic starts with tns1:VideoSurveillanceSystem/ - tns1:VideoSource/MotionDetectorTrigger
MotionDetectorTrigger events only - tns1:VideoSurveillanceSystem//.|tns1:FireAlarm/Alarm
Events where the topic starts with tns1:VideoSurveillanceSystem/, as well as FireAlarm/Alarm events - tns1:VideoSource/
All events of the video system, they contain a comment in Axxon PSIM format
- tns1:VideoSurveillanceSystem//.
- Message Content Filter
- //tt:SimpleItem[@Name="Source" and @Value="{DFC2A44E-7CE4-E711-8A5F-54E6FC817BD7}{CAM.1}"]
Events only from the source with the {DFC2A44E-7CE4-E711-8A5F-54E6FC817BD7}{CAM.1} identifier
- //tt:SimpleItem[@Name="Source" and @Value="{DFC2A44E-7CE4-E711-8A5F-54E6FC817BD7}{CAM.1}"]
Note
When the ONVIF-Server restarts, the filters are reset, and they need to be set again.
Before changing the filter in the Events section, it is necessary to click the Refresh button for the camera in ODM.
