General
Resolution
: Select the image resolution suitable for the surveillance scene. A higher resolution increases bandwidth and storage.
Frame rate
: To avoid bandwidth problems on the network or reduce storage size, you can limit the frame rate to a fixed amount.
If you leave the frame rate at zero, the frame rate is kept at the highest possible rate under the current conditions. A higher
frame rate requires more bandwidth and storage capacity.
Compression
: Use the slider to adjust the image compression. High compression results in a lower bitrate and lower image quality.
Low compression improves the image quality, but uses more bandwidth and storage when you record.
Signed video
: Turn on to add the signed video feature to the video. Signed video protects the video from tampering by
adding cryptographic signatures to the video.
H.26x encoding
Zipstream
: A bitrate reduction technology, optimized for video surveillance, that reduces the average bitrate in an H.264 or H.265
stream in real time. Axis Zipstream applies a high bitrate in scenes where there are multiple regions of interest, for example in
scenes with moving objects. When the scene is more static, Zipstream applies a lower bitrate, and thereby reduces the required
storage. To learn more, see
Reducing the bit rate with Axis Zipstream
Select the desired level of bitrate reduction:
•
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.
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.
