Importing video to C-Werk

To import external video data, do as follows:

1. Create an archive. It must be equal to or larger than the total size of all files in it (see Creating archives).
2. Run IP Device Discovery Wizard (see Adding and removing IP devices):
   1. In the form for manually adding an IP device, select Grundig in the Vendor drop-down list (1).
      
   2. Select ExternalArchive from the models list (2).

   3. Select the archive file to which video recordings will be added (3).

   4. Click the button.

      Attention!

      When you add a camera:

      1. Continuous replication from the on-board  storage to the selected archive file (see Configuring data replication).
      2. The Scene Analytics object will be created (see Creating detection tools) and metadata enabled (see Setting general parameters of Tracker-based Scene Analytics detection tools). 

3. Configure Object Tracking (see Setting general parameters of Tracker-based Scene Analytics detection tools). If you want to find persons and car numbers in video footage, then create and configure the appropriate detection tools (see Configuring License plate recognition (VT), Configuring Face detection).

   Attention!

   Do not remove the Object Tracker from your system. Otherwise you cannot import videos into your system.

4. If necessary, change the mode of data replication (see Configuring data replication). If you select On Demand mode you can start the analysis of the video image manually (see Indexing video from external sources).

   Attention!

   Replication is performed only to the end of the archive. It is not possible to overwrite existing data in the archive (see Configuring data replication).

   If you ignore this rule, the videos will not be indexed.

   It's preferable to import all the videos from a folder at once, otherwise you have to manually remove metadata and records from the Archive before the next replication (see Indexing video from external sources).

5. In the Folder field, specify the storage location of the video footage that will be used as External Archive.
   

   Attention!

   The following compression algorithms are supported: MJPEG, MPEG-2, MPEG-4, MxPEG, H.264, H.265, Hik264 (x86 only) as well as uncompressed ('raw") video.

   A "raw" format is a stream of consecutive frames without time stamps.

6. Imported folders with video footage or video files must be ISO 8601 timestamped: YYYYMMDDTHHMMSS. 

   1. If the timestamp is in the folder name, all the videos starting from the specified date and time will be imported without exception. The video recordings are ordered according to the file name as follows:

      Note

      For example, if the 20220506T100000_camera1 folder contains 3 files (1.avi, 2.avi, 3.avi), they will come into the archive as follows:

      1.avi: [6 May 2022, 10:00:00; 6 May 2022, 10:00:00 + the duration of 1.avi].

      2.avi: [6 May 2022, 10:00:00 + the duration of 1.avi; 6 May 2022, 10:00:00 + the duration of 1.avi and 2.avi].

      3.avi: [6 May 2022, 10:00:00 + the duration of 1.avi and 2.avi; 6 May 2022, 10:00:00 + the duration of 1.avi and 2.avi and 3.avi].

   2. If the folder name does not have the timestamp, all the video files will be imported in accordance with their timestamps. If the file name is incorrect, the starting point of the recording on the timeline will correspond to the modification date of the file.

      Attention!

      C-Werk operation may be incorrect if video recordings in the folder overlap. No error messages are displayed in this case.

      The date in the folder name or file name (or their creation dates) may not precede the metadata storage period as defined in the system (see Configuring storage of the system log and metadata).

      If you add a Z character to the end of the timestamp, the time zones for the videos will be GMT+0, otherwise – the time zone of the Server.

      For example, 20220228T125130Z.avi. In the Archive mode, this video recording will fit into the timeline from 28 February 2022, 12:51:30 GMT+0 to February 28, 2022, 12:51:30 + recording time GMT+0.

7. By default, live video playback is disabled for the ExternalArchive model. To enable live video playback, select Yes in the Show live video field.
