AXIS P1365-E Network Camera Video and Audio These Zipstream strength options are available: • Off. Zipstream disabled. • Lowest Zipstream strength. Low bandwidth reduction. No visible quality degradation in most scenes • Medium Zipstream strength. Medium bandwidth reduction. Limited visual quality degradation in not prioritized areas in some scenes • Highest Zipstream strength. High bandwidth reduction. Visible quality degradation in not prioritized areas in many scenes Lowest Zipstream strength is the default setting for the product. This configuration is very safe to use in all applications while still reducing the bit rate. For cloud-connected cameras or cameras using edge storage that need to limit the bit rate for increased storage time it is recommended to select the Highest Zipstream strength. This setting is very good to combine with motion detection triggering and variable bit rate (VBR) where the bit rate is allowed to adapt to changes in complexity in the scene. 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. The bit rate controller built into the product can be combined with Zipsteam to enforce a maximum bit rate (MBR) limit. Axis Communications recommends using VBR or MBR with a rather high bit rate limit to enable the full potential of Axis’ Zipstream Technology. MJPEG 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 give poor image quality. To prevent increased bandwidth and storage usage, the maximum frame size should be set to an optimal value. 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 Events on page 43. • When setting up continuous recording. See Continuous Recording on page 49. • In the Live View page – select the stream profile from the Stream profile drop-down list. For quick setup, use one of the predefined stream profiles. Each predefined profile has a descriptive name, indicating its purpose. If required, the predefined stream profiles can be modified and new customized stream profiles can be created. 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. Camera Settings The Video & Audio > Camera Settings page provides access to advanced image settings for the Axis product. Capture Mode Capture mode defines the maximum resolution and maximum frame rate available in the Axis product. A capture mode with a large maximum resolution has a reduced maximum frame rate and vice versa. The capture mode setting also affects the camera’s angle of view as the effective size of the image sensor differs between capture modes. 24
