Normally the system will delete the oldest video and metadata to make place for new video. When deleted this video is lost. To prevent this in case something happens, the video (and metadata) can be tagged so it will not be deleted.

Video tagging can be done in three methods. The first method is using the macro action “Tag video Start” & “Tag video stop”. This allows for automatic tagging when an event occurs or manually when assigned to a layout button. The second method is using the API function “/wiki/spaces/KB/pages/948045061” with the actions server.tagVideoStart and server.tagVideoStop. Using the API function allows for retrospectively video tagging up to 24 hours using the pretime parameter. The third method is using the Timeline panel. This allows an operator to retrospectively video tag any recorded data manually.

While the systems becomes full with tagged video several “storage full” SystemEvents will be fired so the client can be notified of this. Events will be fired on 30, 60, 90 and 100 percent of locked storage space.

Tagged video always need to be manually released using the Sense Client or the API function /wiki/spaces/KB/pages/950993085.

Method 1: Macro action

To create a video tag using the macro engine, create either a Server or a Viewer macro with a signal of your choice. Finally, create as the macro action:

Viewer macro:

Server macro:

Method 2: Execute action

How to use the API function for video tagging can be found in the API documentation

Method 3: Timeline (2.5.12+)

In 2.5.12, it’s possible to tag video using the Timeline panel. The advantage of using the timeline is that previously recorded data can still be tagged. This is contrary of method 1 & 2, which will tag live video.

To create a video tag with the timeline, open a layout containing a video playback panel and the timeline. Select the range which you would like to tag in the time ribbon, and click the “Video Tag” button to open the ‘Add Video Tag’-dialog.

The dialog contains the following information:

Start
