About Zipstream
Axis' Zipstream Technology is a bitrate reduction technology optimized for video surveillance. Zipstream reduces the average bitrate
in the H.264 stream by removing unnecessary data, which makes it possible to stream higher resolutions, reduce storage cost
or keep recordings for a longer time.
To reduce the bitrate, Zipstream reduces the number of bits in the areas of the image that are less interesting from a video
surveillance perspective, for example the background. Image details that are important for forensic video analysis, for example faces
and license plates, are preserved with enough number of bits.
Axis' Zipstream Technology for H.264 conforms to the H.264 standard and is compatible with third-party clients and VMS solutions
that decode H.264 video.
About MJPEG settings
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. Setting the frame size to the Default setting
provides consistently good image quality at the expense of increased bandwidth and storage usage in low light. Limiting the frame
size optimizes bandwidth and storage usage, but may result in poor image quality.

About stream profiles

A stream profile is a set of predefined stream settings including resolution, compression, frame rate and overlay settings. Stream
profiles can be used:
• When setting up recording using action rules. See About events on page 41.
• When setting up continuous recording. See About continuous recording on page 47.
• In the Live View page – select the stream profile from the Stream profile drop-down list.
To create a new profile or modify an existing profile, go to Setup > Video & Audio > Stream Profiles.
To select a default stream profile for the Live View page, go to Setup > Live View Config.
