AXIS P1346/-E/AXIS P1347/-E - Video & Audio
Overlay Settings
To place an overlay image at specific coordinates in the view
area, check Include overlay image at coordinates and enter
the X and Y coordinates. The overlay image must first be
uploaded to the network camera, see
Overlay Image,
on page
20.
Text, date and time can also be used as an overlay.
Click for information on available options.
Audio
Select the Enable Audio box option to enable audio in the
video stream.
Audio configuration settings are the same for all video
streams and configured under Video & Audio > Audio
Settings; see page 22. The current audio configuration is
displayed under Current Audio Settings.
Note:
The box option Enable Audio Support under System
Options > Security > Audio Support must also be selected to enable sound in the product. See
Audio Support,
on
page 36.

GOV Settings
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 adverse effect on image quality.
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 frame rate or image quality. 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 & Audio > Video Stream > Image. Under Overlay Settings,
check the Include text checkbox 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.
