Select the bitrate reduction Strength:
• Off: No bitrate reduction.
• Low: No visible quality degradation in most scenes. This is the default option and it can be used in all
types of scenes to reduce the bitrate.
• Medium: Visible effects in some scenes through less noise and a slightly lower level of detail in
regions of lower interest, for example, where there’s no movement.
• High: Visible effects in some scenes through less noise and a lower level of detail in regions of lower
interest, for example, where there’s no movement. We recommend this level for cloud-connected
devices and devices that use local storage.
• Higher: Visible effects in some scenes through less noise and a lower level of detail in regions of lower
interest, for example, where there’s no movement.
• Extreme: Visible effects in most scenes. The bitrate is optimized for smallest possible storage.
Optimize for storage: Turn on to minimize the bitrate while maintaining quality. The optimization does not
apply to the stream shown in the web client. This can only be used if your VMS supports B-frames. Turning on
Optimize for storage also turns on Dynamic GOP.
Dynamic FPS (frames per second): Turn on to allow the bandwidth to vary based on the level of activity in the
scene. More activity requires more bandwidth.
Lower limit: Enter a value to adjust the frame rate between minimal fps and the stream default fps based on
scene motion. We recommend you to use lower limit in scenes with very little motion, where the fps could
drop to 1 or lower.
Dynamic GOP (Group of Pictures): Turn on to dynamically adjust the interval between I-frames based on the
level of activity in the scene.
Upper limit: Enter a maximum GOP length, that is, the maximum number of P-frames between two I-frames.
An I-frame is a self-contained image frame that is independent of other frames.
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.
– Click to calculate the target bitrate based on available storage, retention time, and bitrate
limit.
– 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.
