Video

This section describes how to configure the video encoder, and is intended for product Administrators, who have unrestricted

access to all the configuration menus; and Operators, who have access to the settings for Video & Image, Live View Config,

and Event Configuration.

You can configure the video encoder by clicking Setup

in the top right-hand corner of the Live View page. Click on this

page to access the online help that explains the configuration menus.

Video Stream

The video stream settings are separated in tabs:

•Image

• H.264

•MJPEG

Image

Image Appearance

Use these settings to modify the image resolution and

compression. Setting the compression level affects the

image quality and the amount of bandwidth required,

the lower the compression, the higher the image quality

with higher bandwidth requirements. The image can also be mirrored (reversed) and rotated. See the online help files for

more information.

Video Stream

To avoid bandwidth problems on the network, the frame rate allowed to each viewer can be limited. Select the Unlimited

radio button to allow the highest available frame rate or select the Limited to... radio button and enter a value (1-30) fps in

the field.

Overlay Settings

Use these settings to include an text, date, and time as

overlay. Click for information on available options.

Preview

For a preview of the image before saving, select video

format and Open. When satisfied with the settings,

click Save.

H.264

GOV Settings

The GOV structure describes the composition of the

video stream and setting the GOV-length to a higher

value saves considerably on bandwidth.

Bit Rate Control

The bit rate type can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to image

complexity, using up more bandwidth for increased activity in the image, and less when the monitored area is quiet.
