Video Stream

Define the maximum video stream time per session in seconds, minutes or hours, or set it as unlimited. When the set time has expired, a new stream can be started by refreshing the page in the browser. Note that the maximum video stream time does not apply to clients connecting via multicast.

The frame rate allowed to each viewer can also be limited, to avoid bandwidth problems on the network.

Test

For a preview of the image before saving, click Test. When satisfied with the settings, click Save. Please note that the preview image will be in JPEG format, even though the settings are valid both for Motion JPEG and MPEG-4.

Please refer to the online help for more information.

Advanced - Camera Settings

This page contains settings for fine-tuning the video image. These include the color level, brightness, sharpness and exposure control.

Please see the online help for further information on these settings.

Low Light Behavior

Exposure priority defines the balance between image quality and the frame rate. Higher image quality may reduce frame rate and increase motion blur. A prioritized frame rate may instead increase the image noise. Depending on requirements, use this to give higher priority to the image quality or to the frame rate.

Advanced - MPEG-4 Settings

GOV Settings

The GOV structure describes the composition of the MPEG-4 video stream. Setting the GOV-length to a high value saves considerably on bandwidth. The Cyclic refresh parameter gives a smoother bit rate and can be useful if bandwidth is limited.

Note: Cyclic refresh should not be enabled if Event handling is enabled and the file format is set to MPEG-4 in Upload images/video (see Setup > Event configuration > Event settings).

Bit Rate Control

Limiting the maximum bit rate is a good way of controlling the bandwidth used by the MPEG-4 video stream. Leaving the Maximum bit rate as unlimited will provide consistently good image quality, but at the expense of increased bandwith usage whenever there is more activity in the image. Limiting the bit rate to a defined value will prevent excessive bandwidth usage, but images will be lost when the limit is exceeded.
