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.
• 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 19.
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 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.
The bit rate can be set as Variable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image
complexity, using up more bandwidth for increased activity in the image, and less for lower image activity. CBR allows you to set a
fixed Target bit rate that consumes a predictable amount of bandwidth. As the bit rate would usually need to increase for increased
image activity, but in this case cannot, frame rate and image quality are affected negatively. To partly compensate for this, it is
possible to prioritize either frame rate or image quality. Not setting a priority means that frame rate and image quality are equally
affected. You must save your settings before they can take effect.
The current bit rate can be set to appear as text overlay. To do this, select the Include text check box option under Overlay
Settings and enter the modifier #b in the field.

Stream Profiles

A stream profile is a set of predefined stream settings including resolution, compression, frame rate and overlay settings. Stream
profiles can be used:
• When setting up recording using action rules. See Events, on page 30.
• When setting up continuous recording. See Continuous Recording, on page 33.
• In the Live View page – select the stream profile from the Stream profile drop-down list.
For quick setup, use one of the predefined stream profiles. Each predefined profile has a descriptive name, indicating its purpose. If
required, the predefined stream profiles can be modified and new customized stream profiles can be created.
To create a new profile or modify an existing profile, go to Setup > Video > Stream Profiles.
To select a default stream profile for the Live View page, go to Setup > Live View Config.
