AXIS Q6035 PTZ Dome Network Camera
Video and Audio
H.264
The GOV structure describes the composition of the video stream and setting the GOV-length to a higher value saves considerably on
bandwidth but may have an a dverse effect on image qua lity.
ThebitratecanbesetasVariable Bit Rate (VBR) or Constant Bit Rate (CBR). VBR adjusts the bit rate according to the image
complexity, using up more bandwidth for incre as e d activity in the image, and less for lower activity in the monitored area. 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 im age activity, but in this case c annot, the frame rate and image quality are affected negatively. To partly
compensate for this, it is possible to pri oritize either the frame rate or the image quality. Not setting a priority means the frame rate
and image quality are e qually 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 code #b in the field.
MJPEG
Sometimes the image s ize 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 im age quality at the expense of increased bandwidth and s torage usage in low light. Limiting the frame
size optimizes bandwidth and storage usage, but may give poor image quality. To prevent i ncreased bandwidth and storage usage,
the maxim um frame size should be set to an optimal value.
Stream Profiles
There are four pre-programmed stream profiles available for quick set up. The settings for these can be adjusted. New customized
profiles can also be created. Each profile has a descriptive name, indicating its purpose.
•Thestreamprofiles can be accessed from the Stream profile drop-down list in the Live View page.
• To add, copy, modify, and remove stream profi les go to Video & Audio > Stream Profiles.
• To select the default stream p rofile go to Live View Config > Stream Profile and choose the profile from the dro p-down list.

Camera Settings
The Video & Audio > Camera Settings page provides access to advanced image settings for the Axis product.
Capture mode
Capturemodedefines how ima g e data is taken from the ima ge senso r in regards to resolution and frame rate, p rioritizing either one
or the other. The capture mode is set the first time the camera is accessed. See
Configure capture m ode, on page 8
.
To change the capture mode setting, select the desired Capture Mode from the drop-down list and click OK. When the capture
mode setting is changed, most other settings, for example motion detection w indows and events, will be removed or reset. Stop all
video streams before changing the capture mode.
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.
Increasing the Sharpness can increase bandwidth usage. A sharper image might increase image noise es pecially in low light
conditions. A lower setting reduces image noise, but the whole image will appear less sharp.
