We often receive feedback regarding an issue with Generic Events, specifically related to the Show desktop notification action, with or without the Force Acknowledgment option. In this case, people mention that thumbnails aren’t displayed in the notification panel and bookmarks – if Force Acknowledgment was enabled – are not being created after the event occurred.
Typically, this occurs when the metadata for the Generic Event was not added to the request, resulting in the unknown identification of the cameras for which the thumbnails and/or bookmarks should be generated.
To address this matter, it is recommended to include the camera IDs of the relevant cameras in the Generic Event.
How to resolve this issue?
This issue can be resolved by modifying the URL of the Generic Event as follows
For a single camera, the URL should be structured as:
In the case of multiple cameras, the URL should be structured as:
By following these steps, you can ensure that the bookmarks are created accurately and attributed to the desired cameras. If you have any further questions or concerns, please don't hesitate to reach out.
The camera IDs can be collected from the applicable Camera Settings menu, tab General.
What if you can’t add the metadata information?
Sometimes, the resource that sends the Generic Event, doesn’t provide the option to enter these URLs, but offer predefined fields to fill and don’t offer the option to add the metadata information. Typically, these devices are only able to add a Source, Caption, and Description to the Generic Event URL.
In such situation, you can use the Do HTTP(S) request action in the rules engine to work around this limitation.
You need to enable 2 rules for the event:
- Event = Generic Event > Action = Do HTTP(S) request
- Event = Generic Event > Action = Show Desktop Notification + Force Acknowledgment
In case of the Do HTTP(S) request, you use the URLs as structured and mentioned in the previous section of this support article. This will identify the desired cameras that need to be bookmarked in case of the applicable event(s).
