Frequently Asked Questions (FAQ)

Searches

I have set up Face recognition, but no results are returned.

I am not getting any results for Free text search with threshold.

  • Make sure to select the correct object type; for example, if you are searching for "person sitting and looking at their phone", ensure that the object type is set to Person.

How can I improve detection accuracy?

  • Adjust the chosen object type's confidence threshold: lowering it threshold may yield more results, but be aware that it could also increase false positives, and vice versa.

  • Draw a precise region of interest (ROI) around the area you want to search. This helps focus the query on the relevant area.

I would like to get results only when the object appears in the scene, and not when it is already present. How can I do that?

  • Use Multi-condition search with the Appearance filter. This will ensure that results are returned only when the object first appears in the scene.

I would like to search for an object not included in the predefined object types. What can I do?

  • Free text search and Free text search with threshold, you can use Full image search to look for elements in the background not covered by other object types.

Can I edit a Rule after it has been run?

  • No, once a rule has been created and run, it cannot be edited. You can clone the query to create a new one with the same settings, and then modify the cloned query as needed.

Videos & Storage

My Rule used to return results, but now I am only getting results with black thumbnails.

  • This usually indicates that the retention period for the video has expired, and the video has been deleted from the system.

An old result of my Rule no longer shows a thumbnail image.

  • This is most likely due to the storage space allocated to the video being exceeded, which causes older video segments to be deleted.

Can I change indexing parameters after adding a camera/video?

  • No, indexing parameters are set when adding a camera or video and cannot be changed later. If you need different indexing parameters, you will need to remove the camera/video and add it again with the desired settings.
