Video Settings

This section describes how to configure the video encoder, and is intended for product Administrators, who have unrestricted
access to all the Setup tools; and Operators, who have access to the settings for Video, Live View Config, and Events.
You can configure the video encoder by clicking Setup in the
top right-hand corner of the Live View page. Click
this page to access the online help that explains the setup
tools.

Video Stream

The video stream settings are separated into 3 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 and the higher the bandwidth
requirements. Enable aspect ratio correction to improve the image appearance when video from an analog camera is
displayed on a digital screen (for example a computer monitor). The image can also be mirrored (reversed). 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 a text, date and time as
overlay. Click for information on available options.
Preview
For a preview of the image before saving, select a video
format and click Open... When satisfied with the
settings, click Save.
H.264
GOV Settings
The GOV structure describes the composition of the
H.264 video stream which consists of 2 image forms,
I-images and P-images. An I-image is a complete
image, whereas a P-image is only the differences in the image as compared with the previous image. The GOV length
determines how many P-images are sent before the next complete I-image is sent. Setting the GOV-length to a higher value
saves considerably on bandwidth but if there is congestion on the network, there may be noticeable decay in the video quality.
Setting the GOV-length to a lower value increases the video quality, in this case.
GOV length should not be higher than the set frame rate when using a pre-trigger buffer see Pre-trigger and post-trigger
buffers, on page 17.
