The Search in archive component also allows querying small video fragments from an object. 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 and Camera fields are automatically filled.

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

   The video fragment is exported at ATM-Intellect Pro using the Axxon_player.exe utility, which is part of base Intellect installation. This utility does not support the function of frame by frame export. This means that the whole clip or set of clips corresponding to the selected date and time will be exported, depending on the value of the Length (sec) parameter. In the context of a single clip, it's impossible to request only part of it.

   
   

6. To reduce use of network bandwidth the Bandwidth list is used.
7. In the Start area select time to perform request: Immediately or Schedule.
8. Timeout of video receiving is set in the Data receive timeout, sec field.
9. If the Open immediately checkbox 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.
10. If the value in the Length (sec) is more than 120 you will be proposed to use 120 value. This is done so that the user could consciously create queries in the result of which a large data file will be exported from the video archive on the ATM-Intellect Pro. To remove that restriction click Settings in the bottom left part of the Search in archive window and in the appeared dialog box specify the Maximum length of loaded video clip, sec value. After all fields values are specified, press New.
    
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.
    

    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 Restart button.

    
    

13. You can stop loading the video fragment at any time, by clicking the Pause button.
14. If the Open immediately checkbox is set, after it is loaded, the video fragment will be played in the Axxon Player.
    

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. To change temporary files storage time set the required value in days in the StoreVideoFiles parameter of DWORD type in the HKLM\SOFTWARE\BITSoft\VHOST\VHostService registry branch for 32-bit OS (HKLM\SOFTWARE\Wow6432Node\BITSoft\VHOST\VHostService for 64-bit OS). When the parameter is changed restart the Videosrv.exe.

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 p. 10).
