Note
H.264 is a licensed technology. The Axis product includes one H.264 viewing client license. To install additional unlicensed
copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.
H.264 can, without compromising image quality, reduce the size of a digital video file by more than 80% compared to the Motion
JPEG format and by as much as 50% compared to older MPEG formats. This means that less network bandwidth and storage space
are required for a video file. Or seen another way, higher video quality can be achieved for a given bitrate.
H.265 or MPEG-H Part 2/HEVC
H.265 can, without compromising image quality, reduce the size of a digital video file by more than 25% compared to H.264.
Note
• H.265 is licensed technology. The Axis product includes one H.265 viewing client license. Installing additional unlicensed
copies of the client is prohibited. To purchase additional licenses, contact your Axis reseller.
• Most web browsers don't support H.265 decoding and because of this the camera doesn't support it in its web interface.
Instead you can use a video management system or application supporting H.265 decoding.
How do Image, Stream, and Stream profile settings relate to each other?
The Image tab contains camera settings that affect all video streams from the product. If you change something in this tab, it
immediately affects all video streams and recordings.
The Stream tab contains settings for video streams. You get these settings if you request a video stream from the product and don't
specify for example resolution, or frame rate. When you change the settings in the Stream tab, it doesn't affect ongoing streams, but
it will take effect when you start a new stream.
The Stream profiles settings override the settings from the Stream tab. If you request a stream with a specific stream profile, the
stream contains the settings of that profile. If you request a stream without specifying a stream profile, or request a stream profile
that doesn't exist in the product, the stream contains the settings from the Stream tab.
Bitrate control
Bitrate control helps you to manage the bandwidth consumption of your video stream.
Variable bitrate (VBR)
Variable bitrate allows the bandwidth consumption to vary depending on the level of activity in the scene. The more activity,
the more bandwidth you need. With variable bitrate you are guaranteed constant image quality, but you need to make sure
you have storage margins.
Maximum bitrate (MBR)
Maximum bitrate lets you set a target bitrate to handle bitrate limitations in your system. You might see a decline in image quality or
frame rate as the instantaneous bitrate is kept below the specified target bitrate. You can choose to prioritize either image quality
