Archive review

You can go to an archive in several ways:

  • Click in the menu;
  • Click in the camera window;

  • open context menu on the channel image and select Open archive;

  • press TAB to open an archive of the selected channel or CTRL+TAB to open an archive for all the channels in the template.

TRASSIR can save 2 streams from the the connected devices to the archive: mainstream and substream. Thus, when you open an archive, you decide which stream you need to review.

To determine the required archive, select it from the context menu by right click on the image or the archive icon:

  • Archive on [server_name] - the archive stored on the specified channel will be opened. Mainstream or substream will be selected automatically, in accordance with the camera window view settings. This is the default mode.
  • Archive on [server_name] (prefer substream) - the substream of the archive, stored on the specified channel, will be opened. This feature lets save the traffic and reduce the CPU load on operator's workplace.
  • Archive on the device - the archive from the device's storage drive (Flash-drive or HDD\SDD disk) will be opened.

Archive controls are given below:

  • Timeline - represents video record availability in the archive. The color of the timeline lets discover the archive recording method: permanent or on detector. If on detector method is used, the density of the timeline coloring represents the presence of detected motion and its intensity. The more red coloring it has, the more motion has been detected in the picture.

    Tip

    The timeline can change its coloring only on those channels which have ActiveSearch activated.

  • Player control panel - it is a set of buttons to control archive review. The number of buttons depends on the archive view window width.

The timeline lets you:

  • Move the blue playback tag to any archive fragment by clicking on the required timeline place.
  • To move the scale back or forth hover the timeline to see the icon , left click and without releasing start moving the timeline back and forth.
  • Use the mousewheel to scale the timeline. You can also change the scale using left (to scale in) or right (to scale out) mouse buttons. To do this, hover the timeline (but not the red line!) and press the corresponding button.

  • When you move the cursor through the archive scale, you'll see the archive thumbnails which will help you to identify the start of the playback.

    If the timeline was scaled out to a great extent, you can hold the cursor over it for one second, while searching for the required fragment, and you'll see the timeline of larger scale.

  • The blue coloring of the timeline determines the permanent archive recording.

Player control panel lets you:
