Player for H.264 Live Video

This page shows the H.264 live video stream in the browser. You can access this page either in guest mode or in administrator mode.

To see the H.264 video stream, you need an installed plugin, such as the "Apple QuickTime Plugin" or the "VLC Plugin" for the browser you are using.

Frame Rate

This parameter allows setting the desired frame rate. Please note that the frame rate depends to a large degree on the bandwidth of the transmission path, the selected resolution and the configuration of the H.264 video codec.

For more details, open the H.264 RTP Server Settings dialog.

Function Selection

Display Mode

Depending on the camera model, you can use this option to display different views of corrected (i.e. undistorted) images. The Full Image display mode shows the image without further processing All other modes show an image that has been pre-processed in the camera. This means that you can use zooming and virtual PTZ (vPTZ).

Caution

Pre-processing of images results in reduced frame rates of the H.264 video stream.

Presets for Image Quality and Resolution

This section allows using different presets for image resolution and image quality.

In scenes that show a lot of movement, the CPU load increases due to H.264 encoding. Note that you should reduce either the frame rate or the image quality in such a scene.

  • The presets with the (fast) addition are optimized for stable frame rates. As the load increases, the system automatically reduces the image quality in order to maintain the desired frame rate.

  • The presets with the (quality) addition are optimized for image quality. If the CPU load reaches 100%, the system automatically reduces the frame rate while maintaining image quality.

The following table shows an overview of the available presets.

Camera

On system with dual image sensors, this parameter selects the image sensor that is to be used for H.264 encoding.

Enable Audio

Use this parameter to include audio in the H.264 video stream. Note that this option is only available if a corresponding audio input has been configured and activated in the Microphone and Speaker dialog.

Rotation

Use this parameter to rotate the image by 180 degrees. Note that rotating the image will reduce the frame rate, especially when encoding images with higher resolutions.

Enable RTP Server

This parameter controls operating mode of the RTP server. There are three types of operating modes:

Operating Mode

Description

Off

The RTP server with H.264 video encoding is not running.

On

The RTP server with H.264 video encoding is running permanently. Video encoding is permanently active in this mode and can be used at any time without delay.

Auto

The RTP server is running permanently, but H.264 video encoding is only activated if needed. The server automatically switches between regular operation and H.264 encoding when clients are requesting and.264 video stream.

Activate Multicast

Use this parameter to switch between RTP Unicast and RTP Multicast. Multicast mode is only available if the RTP server is running permanently. More configuration options for the Multicast mode are available in the H.264 RTP Server Settings dialog.

Exposure Control

Select an area that will be used for exposure control:

  • Visible Image Area: The correct exposure will be determined on the basis of the visible image section.

  • Full Image: In this setting, the entire area of the image sensor will be used for exposure control. However, you can also use exposure windows for exposure control:

    • Predefined exposure windows

    • Custom exposure windows

For additional information on this topic, see the Exposure Settings help page.

Brightness

Use this parameter if you would like to brighten up the entire image area (see Exposure Settings).

Backlight Correction

This parameter (similar to Brightness) also is used to control image brightness. However, it only affects the darker portions of an image (see Exposure Settings).

Color Saturation

Use this parameter to influence the color saturation of the image. The higher the saturation, the more intense are the colors. The value -10 produces a gray-scale image (see Color Settings).

Microphone Sensitivity

This parameter sets the sensitivity of the camera microphone.
