Video
• Baseline. The Baseline prole is recommended for clients that don’t support CABAC entropy coding.
• Main. The Main prole provides higher compression with maintained video quality compared to the Baseline prole but
requires more processing power to decode.
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. When the activity in
the scene increases, the bit rate would usually increase as well. If there is a surplus in bandwidth, this may not be an issue and
selecting Variable bit rate (VBR) will be sufcient. But if bandwidth is limited, it is recommended to control the bit rate by selecting
Constant bit rate (CBR). When the activity in the scene increases, VBR adjusts the bit rate according to the complexity, using up
more bandwidth for increased activity in the scene, and less for lower scene activity. CBR allows you to set a target bit rate that
limits the bandwidth consumption.
The CBR target bitrate works like the ceilingof a tent. It limits thebit rate, while maintaining some exibility. The bit rate maybounce
up and down within the set target but when it nears the set target value, the limitation kicks in. However, because CBR will always
prioritize a continuous video stream, it allows temporary overshoots from the target bit rate. Because setting a target value prevents
the bit rate from increasing, frame rate and image quality are affected negatively. To partly compensate for this, select which variable
shall be prioritized, frame rate or image quality. Not setting a priority means that frame rate and image quality are equally affected.
The current bit rate can be set to appear as text overlay. Under Overlay Settings, select Include text and enter the modier
#b in the eld.
To apply the settings, click Save.
MJPEG
Sometimes the image size is large due to low light or complex scenery. Adjusting the maximum frame size helps to control the
bandwidth and storage used by the Motion JPEG video stream in these situations. Setting the frame size to the Default setting
provides consistently good image quality at the expense of increased bandwidth and storage usage in low light. Limiting the frame
size optimizes bandwidth and storage usage, but may give poor image quality. To prevent increased bandwidth and storage usage,
the maximum frame size should be set to an optimal value.
Stream Proles
A stream prole is a set of predened stream settings including resolution, compression, frame rate and overlay settings. Stream
proles can be used:
• When setting up recording using action rules. See Events on page 34.
• When setting up continuous recording. See Continuous Recording onpage 39.
• In the Live View page – select the stream prole from the Stream prole drop-down list.
For quick setup, use one of the predened stream proles. Each predened prole has a descriptive name, indicating its purpose. If
required, the predened stream proles can be modied and new customized stream proles can be created.
To create a new prole or modify an existing prole, go to Setup > Video > Stream Proles.
To select a default stream prole for the Live View page, go to Setup > Live View Cong.
Camera Settings
The Video > Camera Settings page provides access to advanced image settings for the Axis product.
Image Appearance
Increasing the Color level increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a
black and white image.
The image Brightness can be adjusted in the range 0–100, where a higher value produces a brighter image.
