AXIS M7001 - Video Settings

Bit Rate Control

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 bandwidth for increased 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 image activity, but in this case cannot, the frame rate and image quality are affected

negatively. To partly compensate for this, it is possible to prioritize either the frame rate or the image quality whenever the bit

rate needs to be increased. Not setting a priority means the frame rate and image quality are equally affected.

Note:

To determine a reasonable bit rate, go to Setup > Video > Video Stream > Image, check the Include text checkbox

under Overlay Settings and enter the code #b in the field. The current bit rate will display as a text overlay on the Live

View page.

To preview the image stream while configuring the GOV settings and Bit rate control, select Open... under Preview.

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. Defining the frame size as Unlimited

provides consistently good image quality at the expense of increased bandwidth and storage usage during 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 Profiles

There are 4 pre-programmed stream profiles available for quick set-up. Their settings can be adjusted and/or new customized

profiles can be created. Each profile has a descriptive name, describing its usage and/or purpose. The profiles can be accessed

from the Live View page.

Go to Setup > Video > Stream Profiles to set up and configure stream profiles.

• To create a new stream profile, click Add to bring up the Stream Profile Settings panel:

1. Enter a unique name and a description for your profile.

2. Select a Video encoding (H.264 or MJPEG) from the drop-down list.

3. Modify the video stream settings under the Image and H.264 or MJPEG tabs. See Video Stream, on page 11.

4. Click OK to save the profile.

• To copy an existing stream profile, select the profile and click Copy. Enter a new profile name and modify the settings in

the Stream Profile Settings panel.

• To modify an existing stream profile, select the profile and click Modify to open the Stream Profile Settings panel. Change

the settings as above. For pre-programmed profiles, the original settings can always be restored by clicking the Restore

button.

• To remove a stream profile, select the profile and click Remove. Pre-programmed profiles cannot be removed.

Camera Settings

This page provides access to the advanced image settings for the AXIS M7001.

Image Appearance

Color level - Select an appropriate level by entering a value in the range 0-100. Lower values mean less color saturation,

while the value 100 gives maximum color saturation.

Brightness - The image brightness can be adjusted in the range 0-100, where a higher value produces a brighter image.

Contrast - Adjust the image's contrast by raising or lowering the value in this field.

Rotate image - The image can be rotated to the correct orientation. Select the appropriate value from the drop-down

list.
