To request a playback, follow the steps below.
When switching from the Video tab to another one before the playback is loaded, the system notifies you by means of a pop-up message as soon as it is loaded.
The requested playback is displayed in the right part of the window. To watch it, click on the play icon or move the slider on the timeline.
The timeline can be completely white or grey, or it can consist of white and grey segments. White means that no data is available for the time period, and grey means that a playback is available from at least one of the selected cameras.
When watching playbacks, the following functions are available:
Icon | Function |
Play video. | |
Pause video. | |
/ | Enable or disable high video quality. The availability of high quality and its features depends on the device type and its configuration. In the case of some device types, high quality can be available for live streams but unavailable for playbacks. If the device doesn’t support quality change, this icon is not clickable (). |
Switch to full screen. You can open all playbacks at once, or each one separately. To do this, click on this icon in the lower-right corner of the tab or playback section, respectively. The icon is shown in the section when you point to it. | |
Exit the full-screen mode. You can use the Esc key instead. | |
/ | Switch the sound on or off. The icon is displayed when you point to a section of an individual playback. You can play the sound from only one playback at a time. If a playback is open in full screen mode, you can play the audio of only this playback. If the icon is displayed after you start playing the playback, its sound is unavailable. |
Show/Hide a section with a map which shows the unit moving along its track at the time the video was recorded. Hover over the unit icon or a track point to see the information from the message received at that location. | |
Open the list of the configured unit cameras. If you want to hide the playback of a certain camera, cancel its selection. Select the camera again to make its playback appear on the screen. |
You can save the required playback excerpt as a file which is later available on the Files tab, in messages, and in reports. There are two ways to do this:
The video quality of the saved excerpt depends on the device quality settings.
To save a playback excerpt in the first way, request a playback using the instructions above and follow these steps:
To save a playback excerpt in the second way, follow these steps:
Select the Save requested file to Files in the Action section.
Specify the duration before and after the event in seconds. The minimum allowed value is 1, and the maximum value is 30. The duration of the file you want to save is equal to the sum of the specified values.
Click Request.
The requested excerpt is saved only if the playback for the specified period is available on at least one of the selected cameras.
If the excerpt you are saving contains intervals with no data from all the cameras, the number and duration of the saved files is equal to the number and duration of intervals with available data.
In addition to the manual saving, you can configure the automatic saving of files in Wialon. To do this, create a notification with the Save a video as a file action.
