The VIEWER tab’s main content area features thumbnails of video extracted from all camera sources added to the case. Thumbnails are sorted chronologically by default, and by relevance when filters are applied.

You can change the size of the thumbnails using the Grid drop-down list.

The time range bar at the top of the Objects pane indicates the first and last objects in the filtered objects.

Click the selection button when hovering over object thumbnails to select one or more objects. You can then use the action buttons in the top right-hand corner (see below) to include these objects in the License Plate Recognition, Face Recognition, Proximity or Appearance Similarity filters, to add them as bookmarks to a case report or to export the face thumbnails.

Close-up Clip Display

The name of the VIDEO SYNOPSIS® appears above the close-up clip area.

The following information will appear under the close-up playback area when relevant:

  • Event Time – the date and time at which the event was first recorded in the original video.

  • End Time – the date and time when the event ended.

  • File Name – indicates the original file name for a reference even in a multi-file same-camera synopsis.

  • License Plate – if the object has a detected license plate, the license plate number will appear.

When face or plate watchlists are used, additional information regarding the watchlist will also be displayed.

Original Video Display

In the Original Video tab, you can view the playback of a clip of the original video featuring the object. When you play the original video, a bounding box will appear by default around the object in the close-up.

Note

BriefCam can detect objects whose duration in the scene is very short, less than 10 frames. However, for such objects no original video clip is generated.

At the top of the original video, you’ll see the following options (when available):
