Parallel to the continuous video recording, triggered video sequences can be recorded. As described in chapter "Principles of video recording", particular video sequences are stored protected on ibaCapture Server by means of video triggers during video recording to protect the video data against being overwritten by the continuous recording.

ibaPDA therefore sends the information on the trigger events to the video server.

In order to record triggered video sequences, the video triggers need to be configured.

Select an existing data storage you want the video recording to be linked with or create a new data storage.

For this purpose, open the "Data storage" dialog by clicking on the icon in the toolbar or on the Configure - Data storage... menu.

Click on the branch "Video protection" to open the video trigger setup dialog.

The available video servers and all active cameras connected to them are displayed in the upper section in a tree structure. All further video triggers to be configured are created under the corresponding (marked) camera.

Up to 10 video triggers can be added to each camera.

Adding an image trigger

You can assign an image trigger to a camera by selecting the camera in the tree structure and pressing the "Add image trigger" button in the toolbar. Alternatively, you can use the context menu (right-click on the camera).

By setting or removing a checkmark in the corresponding checkbox, you can enable or disable every trigger for recording.

The video trigger toolbar is located in the upper section.

Add image trigger, alternatively, a image trigger can be added via the context menu. The relevant camera must be marked for this.

Removing image trigger

Copying marked image trigger to clipboard

Pasting image trigger from the clipboard

If an image trigger was marked, the name can be changed. Furthermore, it is possible to set the index in the rotary field "Index" and the maximum video sequence time. The trigger index defines the order of the triggers for one camera.

For a triggered recording, at least a start trigger has to be configured. Every trigger can have its individual conditions.

The setting of trigger conditions is widely the same as for ibaPDA data storage triggers.

In the "Start trigger" section, both a digital and analog signal can be selected as trigger signal. The following trigger conditions can be selected:

  • Rising / falling edge or log. 0 / log 1 for digital signals

  • Rising / falling edge or below / above level X for analog signals

Optionally, it is possible to define a pre-trigger time.

According to the "Start trigger" section, a trigger signal can be selected with the aforementioned trigger conditions in the "Stop trigger" section. Optionally, it is possible to define a post-trigger time.

The video sequence will start after firing of a start trigger.

The video sequence will stop when the maximum video sequence time has been reached or a stop trigger fires.

If a stop trigger was defined for stopping the recording which, however, did not occur (due to bad level or edge setting), the recording is stopped after lapse of time.

A click on the <OK> button applies the configuration of the data storage.
