AXIS Q9216-SLV Network Camera
The device interface
Upper limit: Enter a maximum GOP length, that is, the maximum number of P-frames between two I-frames.
P-frames: Enter the desired number of P-frames. The higher the number, the less bandwidth is required. However, if there are
network congestion, there could be a noticeable deterioration in the video quality.
H.264 profile:
• Baseline: Use if the video management client doesn't support CABAC entropy coding.
• Main: Use if the video management client supports CABAC entropy coding, to achieve higher compression with
maintained video quality. It requires more processing power to decode compared to the baseline profile.
• High: Use if the video management client supports CABAC entropy coding, to achieve even higher compression than
with the main profile. It requires more processing power to decode compared to the main profile.
Bitrate control:
• Average: Select to automatically adjust the bitrate over a longer time period and provide the best possible image
quality based on the available storage.
-
-
Target bitrate: Enter desired target bitrate.
-
Retention time: Enter the number of days to keep the recordings.
-
Storage: Shows the estimated storage that can be used for the stream.
-
Maximum bitrate: Turn on to set a bitrate limit.
-
Bitrate limit: Enter a bitrate limit that is higher than the target bitrate.
• Maximum: Select to set a maximum instant bitrate of the stream based on your network bandwidth.
-
Maximum: Enter the maximum bitrate.
• Variable: Select to allow the bitrate to vary based on the level of activity in the scene. More activity requires more
bandwidth. We recommend this option for most situations.
Orientation
Rotate: Rotate the image to match your requirements.
Mirror: Turn on to mirror the image.
Audio
Include: Turn on to use audio in the video stream.
Source
: Select what audio source to use.
Stereo
: Turn on to include built-in audio as well as audio from an external microphone.
Overlays
: Click to add an overlay. Select the type of overlay from the dropdown list:
• Text: Select to show a text that is integrated in the live view image and visible in all views, recordings and snapshots.
You can enter your own text, and you can also include pre-configured modifiers to automatically show for example
time, date, frame rate.

%a shows the day of the week.
Click to calculate the target bitrate based on available storage, retention time, and bitrate limit.
: Click to add the date modifier %F to show yyyy-mm-dd.
: Click to add the time modifier %X to show hh:mm:ss (24-hour clock).
: Click to select any of the modifiers shown in the list to add them to the text box. For example,
