The Search in archive component also allows querying small video fragments from an object on the ATM-Intellect Pro side. To do so, proceed as follows:

  1. Perform the search by captions or by video clips as described above.
  2. The archive results are shown as a list of entries. Click the right mouse button on a field of interest in the list of results. The menu with Video query and Frame query items is displayed.
  3. If Video query item is selected, the Video query dialog box appears. You can also call this dialog box by clicking Video button in the Query group.
  4. The Date and time (1) and Camera (2) fields are filled in automatically.

  5. The Length (sec) field (3) allows specifying the received video fragment duration.

    Note.

    If the Not used value is selected in the Export to avi parameter (5), then one or more clips will be exported which contain the specified time interval relative to the date and time. In the context of a single clip, it's impossible to request only a part of it.

    If you try to set the value of the Length (sec) field to over 120, the value of 120 is offered. This is done to remind the user that such requests can export a big data file from a video archive on ATM-Intellect Pro side. If you want to turn this limitation off, click Settings in the lower-left area of the Search in archive area. In the window that opens, change the value of the Maximum length of loaded video clip, sec field.

  6. If you want to decrease network load, set the Bandwidth __ KBps field (4) to the appropriate value.

  7. The Export to avi parameter (5) allows you to select the format and codec of the requested video clip:

    1. Not used - the video clip will be exported as an archive with a set of directories and files from the VIDEO folder.

    2. Original - the video clip will be exported to an avi-file without transcoding.

    3. Xvid - the video clip will be exported to an avi-file with the Xvid codec.

    4. DivX - the video clip will be exported to an avi-file with the DivX codec.

    5. x264- the video clip will be exported to an avi-file with the x264 codec.

      Attention!

      The export to an avi-file with the specified codec is performed on the ATM-Intellect Pro side using the AviExport.run module. The AviExport.run module version used on the ATM-Intellect Pro should be no lower than 4.10.5.3776, and the required codec should be installed. Otherwise, an error Frame or video clip is not found (archive export error) will be received.

      Note

      If the ATM-Intellect Pro version is lower than 11.0.1520, then the value of the Export to avi parameter will be automatically set to Not used without the possibility of changing it.

  8. In the Start area select time to perform request: Immediately or Schedule (6).

  9. Timeout of video receiving is set in the Data receive timeout, sec field (7).

    Note

    If you request a clip that is longer than one minute, you have to increase the value of the Data receive timeout, sec. parameter. It is necessary to do it, because it takes time to export a large video clip on the ATM-Intellect Pro side. 

  10. If the Open immediately checkbox (8) is set, then after data downloaded completely they will be placed into the archive and visualized. Otherwise data will only be placed into the archive. To view such data you can use the ATM Monitoring Reports component.
  11. After all fields values are specified, press New.

  12. You will get to the Downloads tab where the task performance process is displayed. During receipt of a video fragment, the file's size, amount downloaded and transmission speed are shown. You can stop loading the video fragment at any time, by clicking the Pause button.

    Note.

    In case data have stopped coming during the download, for example if connection with the object is lost, download will be restarted after a random time interval from 1 to 60 seconds. In case of the attempt failure, attempts will be made at intervals of 1 minute. Information on the time remaining to the restart is displayed in the Comment field. Any time you can restart loading manually using the Start button. 


  13. If the Open immediately checkbox was set, after it is loaded, the video fragment will be played in the following way:
    1. on the ATM-Intellect Workstation and the Additional workplace using the Axxon Player utility, if the Not used value was selected in the Export to avi parameter.
    2. on the ATM-Intellect Workstation using the program specified in the AVI-files player parameter (see Setting up the reaction on receiving images and clips), if a value other than Not used was selected in the Export to avi parameter.
    3. on the Additional workplace using the program specified in the AVI-files player parameter (see Interface of Additional workplace configuration tool), if a value other than Not used was selected in the Export to avi parameter.

Successfully completed task is marked with green in the list. Double-click on such task to visualize received video fragment or frame. It is also possible to go to the folder with downloaded videos. For this right-click the corresponding frame and select the Show in folder item.

The Search in archive module supports broken download resume. If during the download the link with ATM-Intellect Pro was lost, after two minutes timeout the download status will be changed into Network failure and in the Commentary field the message will be displayed that no data transferring is performed in the moment. After ten seconds periodic attempts to resume data download will begin. Attempts period is one minute.  After connection with ATM-Intellect Pro is reestablished, data download will continue from the position where it stopped. Broken download resume mechanism is implemented using temporary files that are stored on the ATM-Intellect Pro  and ATM-Intellect Workstation. These files are stored for three days by default. After this time they are deleted. For example, if you create a clip download task and while loading press "Pause" and resume the download in five days, the data will be downloaded from the beginning.

Note

To change the storage period for the temporary files, it is necesary to create the StoreVideoFiles string parameter in the Windows OS registry and set the required number of days as its value (for details, see Registry keys reference guide, for more information about working with the registry, see Working with Windows OS registry). Then it is necessary to restart the Videosrv.exe module.

The old tasks can be deleted from the list with Delete button on the Downloads tab. Tasks are stored for 100 days maximum. If you want to limit the number of tasks that are shown in the Loads tab, use the Task archive size (days) parameter in the Settings window opened by Settings button in the lower left corner of the Search in archive screen (see step 5).

Attention!

If the Intellect software shuts down, all download tasks with “Downloading” status are paused. To resume download start these tasks manually.
