To view a video image, you should select either a camera on the panel (see Searching for video cameras in the Web-Client), or one of the available layouts (see Web-Client GUI).

The Web-Client supports video playback in the following video formats: MJPEG, H.264, H.265. All other formats are trans-coded to MJPEG on the Server. 

H.265 video playback is possible in the following browsers: Safari, Microsoft Edge with HEVC video extension installed, Google Chrome version 107 and higher, if:

  • hardware acceleration is enabled in the browser settings;
  • the video card has hardware support for the H.265 codec.

You can playback a video in the Web-Client with two players: JPEG and MP4. If your browser supports the MP4 format, the MP4 player is used. Otherwise, your videos will be played back with the JPEG player.

  • If your layout contains several video cameras, only the key frames may be displayed in the H.264 format video cameras, depending on the settings (see Web-Client configuration). If you select a specific camera, all frames will be displayed. In the MJPEG video format each frame is displayed.
  • Video records containing b-frames will play choppy.

The Web-Client supports displaying panoramic views for fisheye video cameras. To enable such a display, select Yes for Activate parameter in Panomorph parameters group in the video camera settings in a common Client (see Configuring fisheye cameras).

To select a displayed stream in the Web-Сlient manually (see Camera), do the following:

  1. Click the parameters of the current stream.

  2. Select a stream to be displayed:

    Menu item

    Description

    Auto (GreenStream, default)

    If a stream was selected based on the maximum bitrate, then another stream will be selected only if its bitrate is more than 5% higher than the current one (in order to eliminate frequent switching if the indicators are approximately equal) (see Camera).

    When you enlarge the surveillance window, the video stream switches to a high quality video stream

    High quality

    A high quality video stream is used in the video surveillance window (see Camera)

    Low quality

    A low-quality video stream is used in the video surveillance window (see Camera). 

A selected video stream is saved when switching between the layouts, but after the page reloads, the video stream that was specified when creating the layout will be automatically selected.

Click the button to open the window in full screen. To exit the full screen mode, click the  button again, or press the Esc key. 

To open a temporary layout from a certain camera on the layout, double right-click the camera video image. To return to the layout, double-click the video image again.

You can enable the display of captions in the video camera viewing window. To do this, click on the name of the camera and set the Show subtitles checkbox.
