Image

The default image settings can be configured under Video> Video Stream. Select the Image tab.

The following settings are available:

•Resolution. Select the default resolution.

•Select Aspect ratio correction to improve the appearance of images in the browser when the video stream has a different aspect ratio. Pixels comprising the image are rearranged so as to provide a more accurate representation of the image.

•Compression. The compression level affects the image quality, bandwidth and file size of saved images; the lower the compression, the higher the image quality with higher bandwidth requirements and larger file sizes.

•Rotate image. If required, the image can be rotated.

•Maximum frame rate. To avoid bandwidth problems, the frame rate allowed to each viewer can be Limited to a fixed amount. Alternatively, the frame rate can be set as Unlimited, which means the Axis product always delivers the highest frame rate possible under the current conditions.

•Overlay settings. See Overlay on page 21.

Click Save to apply the new settings.

H.264

H.264, also known as MPEG-4 Part 10/AVC, is a video compression standard that provides high quality video streams at low bit rates. An H.264 video stream consists of different types of frames such as I-frames and P-frames. An I-frame is a complete image whereas P-frames only contain the differences from previous frames.

The H.264 stream settings can be configured from the Video > Video Stream page. Select the H.264 tab. The settings defined in this page will apply to all H.264 streams that do not use a stream profile.

The GOV length is the number of frames between two consecutive I-frames. Increasing the GOV length may save considerably on bandwidth requirements in some cases, but may also have an adverse affect on image quality.
